Shark Point

Shark Point dive site is a true gem of the Andaman Sea. Named for the frequent sightings of leopard sharks in the area, locals know it as Hin Mu Sang. Located just 27 km from Phuket, it’s situated near the Anemone Reef and King Cruiser wreck and is made up of three main pinnacles.

This site boasts the most diverse range of fish and corals among all Phuket and Phi Phi Islands dive sites. Each pinnacle is spaced 15-20 meters apart and is adorned with stunning purple and pink soft corals, as well as beds of table coral, staghorn coral, coral head, and huge sea fans. With an average depth of 15 meters and a maximum of 30 meters, there’s plenty to explore.

Divers typically start at one pinnacle and finish at the next, depending on the currents. With such a wealth of marine life, it’s almost impossible to cover all three pinnacles in just one dive. If you’re looking for an unforgettable underwater adventure, Shark Point is not to be missed.

Marine Life

 

Welcome to Shark Point, where divers can satisfy their craving for adventure and discover some of the most incredible marine life in the area. While the name of the site may suggest that spotting leopard sharks is the main attraction, there is so much more to experience.

Swimming among the stunning sea fans and coral, divers may be surprised to find seahorses and ornate ghost pipefish. But that’s not all, as the site is also home to a variety of fascinating marine creatures such as scorpionfish, lionfish, pufferfish, and blue-ringed angelfish. For those who enjoy the smaller creatures of the ocean, don’t forget to keep an eye out for colorful nudibranchs, dancing shrimp, and boxfish hiding among the rocks and corals.

King Cruiser Wreck

The King Cruiser Wreck: An Advanced Diver’s Delight

The King Cruiser Wreck is a fascinating dive site with an interesting history. Originally a car ferry, the boat sank in 1997 while carrying only foot passengers. Thankfully, there was no loss of life, as the boat sank slowly and several dive boats were around the area to help. The wreck now sits upright on its twin hulls, forming an artificial reef that attracts an abundance of marine life.

At 85 meters long, the wreck is not small, earning it the nickname “Thaitanic.” It’s worth diving more than once, as it’s impossible to see everything in just one dive. The maximum depth is over 30 meters, making it suitable only for advanced certified divers. The top of the wreck is at around 16 meters depth and is marked by a buoy. Divers should use the line attached near the front of the boat to descend and ascend safely.

While the car deck area was accessible in the first few years after the sinking, it has since collapsed, and penetration of the wreck is now prohibited.

Marine Life

The area surrounding the King Cruiser wreck is teeming with marine life, making it a must-see for any diver. Schools of snappers, barracuda, fusiliers, rabbitfish, and goatfish are so abundant that they’ve become a bigger attraction than the wreck itself! With good visibility, the spectacle is simply breathtaking.
As you venture closer to the wreck, you may encounter bamboo or leopard sharks and even the occasional turtle. The wreck also serves as a landmark for nudibranchs, so keep your eyes peeled for these colorful creatures during your dive.

However, it’s crucial for divers to exercise caution and avoid touching anything or putting their hands on the wreck. The King Cruiser has become an artificial reef full of thriving marine life, and it’s important to preserve and protect its delicate ecosystem.

Overall, the King Cruiser Wreck is a unique dive site that offers a glimpse into the past while providing a home for a thriving community of marine life. It’s a must-visit destination for advanced divers looking for a new challenge.

Koh Doc Mai: A diver's paradise...

Despite its name, Koh Doc Mai, or Flower Island, has no flowers to speak of, but that doesn’t make it any less of a wonder to explore. This stunning limestone island stretches vertically down to 30 meters, creating an impressive wall that attracts divers from all over. While the west side boasts a shallow reef teeming with hard coral and marine life, it’s the east wall that truly captivates.

The wall is riddled with cracks, crevices, and caverns, offering endless opportunities to discover hidden treasures. One of the most popular spots is a large cave and a small cave, both found on the east side of the island. While the small cave is narrow and long, it’s worth exploring only for certified cavern divers.

Unfortunately, Koh Doc Mai is uninhabitable and inaccessible, so landing on the island is impossible. But that doesn’t diminish the beauty of its underwater world. This is a diver’s paradise, with plenty of marine life. So, if you’re looking for an unforgettable diving experience, add Koh Doc Mai to your list!

Marine Life

A good variety of small creatures makes this site a favorite for scuba diving activities. Tiger-tale seahorse, ornate ghost pipefish, and anglerfish are among the species frequently found along the wall. Dive slowly and check crevices in the wall or the sea fans, and you may spot them when they move.

The walls are also a paradise for macro photographers, as colorful nudibranchs, flatworms, tiny white eyes morays, and groups of 10 or more dancing shrimp are guaranteed to make an appearance. Do examine cracks and small crevices for giant morays, and enjoy the schools of yellow line snapper, trevally, and fusiliers that usually swim along the wall.

For those interested in bigger fish, look at the blue for great barracuda, and leopard sharks may also catch a few winks at the bottom of the wall.

Bungalow Bay

Bungalow Bay is a sheltered, curved bay offering excellent diving on both sides, making it a versatile dive site for recreational divers and training dives alike. With relatively shallow areas, gentle reef slopes, and plenty of marine life, it is an enjoyable site for divers of different experience levels.

The northern side of the bay features a gently sloping reef covered with staghorn corals and scattered rock outcrops. The reef ranges from around 5 to 22 metres deep, gradually giving way to a sandy bottom. This area offers a relaxed profile with plenty of opportunities to explore the coral formations and search for smaller reef creatures.

On the southern side, extensive fields of staghorn and pore corals cover the reef. Several large granite boulders rise along the edge of the island, creating additional habitats for fish and other marine life. The combination of coral gardens, rocky formations, and sandy areas makes Bungalow Bay an interesting site to explore at different depths.

Marine Life

Bungalow Bay is home to a wide variety of Andaman Sea reef fish, including parrotfish, snappers, groupers, angelfish, butterflyfish, and colourful basslets. In the shallower sections, keep an eye out for shrimpfish, which can occasionally be seen swimming together in small groups.

Patient divers may also discover some of the bay’s more unusual residents, including leaf scorpionfish, razor fish, and ghost pipefish, often well camouflaged among the corals and reef structures.

Siam Bay becomes particularly interesting after sunset. During night dives, the reef comes alive with an impressive variety of small creatures, making it a rewarding site for macro photographers. Look closely around the coral heads, crevices, and feather stars for tiny crabs, shrimps, and other nocturnal marine life that can be difficult to spot during the day.

For divers who enjoy searching for small and unusual creatures, a night dive at Siam Bay can reveal a completely different side of the reef.

Koh Racha Yai Wrecks

Racha Yai Island’s boat wrecks in bays 1 and 2 are a popular attraction for divers of all levels.
Here are some more details about each wreck:

Old Sail Boat Wreck
The Old Sailboat Wreck, located in the northern part of Bay 1, is a fantastic spot for observing marine life. Despite being in bad condition, it attracts large schools of snappers and glass fish and is home to giant moray eels and great barracudas. Ornate ghost pipefish and Jenkins rays have also been spotted around the wreck. Keep an eye out for shrimp and other creatures hiding in the nooks and crannies.

Harruby Wreck
The Harruby Liveaboard is situated between Bays 1 and 2 and is accessible for all levels of certified divers. The wreck is in excellent condition and is the best site for wreck penetration in the area. Schools of batfish and barracuda are frequently seen, and scorpionfish and bannerfish also call the wreck home. Keep an eye out for ornate ghost pipefish and nudibranch, and don’t miss the snake eels that can be spotted in the sand near the wreck.

Old Fishing Boat
The old Thai wooden fishing boat is located further east of Harruby and is rapidly deteriorating. Despite this, it is still an interesting site to explore. The wreck is deeper, with the top at about 24 metres, and contains a lot of common reef fish. It has an eerie feel and makes for great underwater photography opportunities, but it is not safe to penetrate due to its poor condition.

Marla’s Mystery
Marla’s Mystery is a barge wreck that was purposely sunk about 150 metres east of the center of Bays 1 and 2. It is lying at about 34 metres and is not often dived, making it a difficult site to locate. This site is for experienced divers only, and prior notification should be given if you wish to dive this wreck.

Racha Yai Bay 1-2
(a.k.a. Staghorn reef)

Bay 1–2, also known as Staghorn Reef, offers two distinct areas of reef with different depths and underwater landscapes. The site is suitable for a range of divers, from those exploring the shallower coral gardens to experienced divers looking for deeper reef and wreck diving.

Bay 1 has a small, easily overlooked beach and a gently sloping reef extending along the bay. Scattered pore coral heads cover much of the area, with patches of staghorn coral adding variety to the reef. The reef begins at around 5 metres and gradually descends to approximately 20 metres, where it meets the sandy bottom. The relatively shallow profile makes Bay 1 a relaxed area for exploring coral and marine life.

Bay 2 is home to the largest beach and gives the site its nickname, Staghorn Reef. The reef is characterised by abundant coral heads and extensive branching staghorn corals. Starting at around 12 metres, the reef slopes gradually down to approximately 30 metres, offering deeper sections for experienced divers to explore.

Marine Life

The reef is home to a variety of colourful Andaman Sea reef fish, including parrotfish, snappers, groupers, angelfish, butterflyfish and basslets. Look closely around the reef and you may spot trumpetfish swimming alongside groupers, creating interesting encounters for underwater photographers.

For advanced divers, the deeper section offers the opportunity to explore a wreck at around 25 metres. The wreck provides shelter for larger marine life, including giant moray eels and batfish, and adds another dimension to the dive.

With shallow coral gardens, deeper reef and a wreck to explore, Bay 1–2 offers plenty of variety and can be enjoyed by divers with different experience levels.

Racha Yai Bay 2-3
(a.k.a. Lucy’s reef)

Bay 3, also known as Lucy’s Reef, offers a very different underwater landscape from the neighbouring bays. The reef is characterised by a mixture of rocky areas and scattered pore corals, with a distinctive rocky ridge marking the southern end of the reef.

As you explore the site, the transition from hard coral and rocky seabed to a predominantly sandy bottom is an easy way to recognise that you have entered Bay 3. Beyond a few patches of pore coral and scattered coral heads in the shallower areas, much of the bay is covered by sand, creating a different habitat and making the site particularly interesting for divers who enjoy searching for smaller marine life.

Marine Life

As with the other dive sites around the island, parrotfish, snappers, groupers, angelfish, butterflyfish, and basslets are commonly seen around Lucy’s Reef. Cornetfish are also regularly spotted cruising above the reef and sandy areas.

The sandy bottom and coral crevices provide shelter for a variety of smaller creatures. Boxfish and bluespotted boxfish are common in this area, while patient divers may find boxer shrimp and dancing shrimp hiding deep inside cracks, crevices, and pore corals.

Look closely among the coral and rubble, and you may also discover ghost pipefish, expertly camouflaged among the fronds and often easy to overlook.

Lucy’s Reef is a rewarding site for divers who enjoy taking their time and looking beyond the larger reef fish to discover the fascinating macro life of the Andaman Sea.

Racha Yai Bay 4–5
(Waterfall Wall)

Bay 4–5, also known as Waterfall Wall, brings divers back to a more developed hard-coral reef after the predominantly sandy landscape of Bay 3. The reef has a steeper slope and supports a greater variety of coral formations, making it a colourful and interesting site to explore.

Waterfall Wall can be thought of as a smaller version of Staghorn Reef, with extensive branching corals complemented by a wider variety of hard corals and sea anemones. The combination of coral-covered slopes, sandy patches, and reef structures creates plenty of places to explore and search for marine life.

Divers should take particular care with the current at Waterfall Wall. The current can be complex and may suddenly change direction around the middle section of the reef. As conditions can vary during the dive, this site is best explored with appropriate guidance and good awareness of the current.

Marine Life

The reef is home to many familiar Andaman Sea reef fish, including parrotfish, snappers, groupers, angelfish, and butterflyfish.

The sandy bottom can reveal some more unusual encounters. Lucky divers may spot a thornback boxfish or the remarkable seamoth, both of which are masters of camouflage and easy to overlook.

Away from the reef, look into the blue for large schools of yellowtail barracuda. Bigeye trevally can also gather in impressive schools close to the reef, creating spectacular encounters as they move through the water.

In the shallower sections near the reef, divers may occasionally encounter reef sharks cruising along the coral slope.

With its diverse hard corals, schooling pelagic fish, and changing currents, Waterfall Wall offers a dynamic dive with plenty to discover.

The dive sites offer a variety of underwater landscapes, including rock formations, coral gardens, and deep drop-offs. With its pristine waters and rich marine life, Racha Noi is the perfect location for all levels of divers.

For those seeking a thrilling adventure, the southern tip of Racha Noi is a great spot to encounter giant manta rays. However, due to the depth and strong currents, this area is only recommended for experienced divers.

One of the most exciting aspects of Racha Noi is the outstanding visibility, which can reach up to 30 meters. This makes it a perfect destination for underwater photography and videography enthusiasts.

Home Run

Home Run Reef is a long, sloping hard-coral reef and an excellent site for divers who enjoy drift diving. Much of the reef is covered with staghorn, branching and pore corals, with scattered rocks adding variety to the underwater landscape.

The steepest section of the reef lies at around 12 to 15 metres, before continuing down through depths of approximately 15 to 25 metres and eventually giving way to a gently sloping sandy bottom.

Because of the prevailing current, a one-way drift dive is usually the most practical and enjoyable way to explore Home Run Reef. Rather than swimming against the current, divers can relax and let the water carry them along the reef while taking in the coral formations and marine life.

Marine Life

The reef is home to a variety of colourful reef fish, including parrotfish, butterflyfish, and basslets. Look carefully among the coral branches and rocky formations for some of the site’s more unusual residents.

Cometfish can sometimes be found sheltering in cavities or tucked between the branches of staghorn coral. Trumpetfish and cornetfish are also frequently seen close to the reef, where their slender bodies and camouflage allow them to blend almost perfectly with the coral.

Great barracuda are another regular sighting at Home Run Reef and may be seen cruising along the reef or passing through the blue.

For keen-eyed divers, there is plenty to discover closer to the bottom. Check beneath rocks and around small crevices for reef octopuses and sea snakes, which can be surprisingly well camouflaged.

With its sloping coral reef, flowing current, and abundant marine life, Home Run Reef is a particularly rewarding site for drift-diving enthusiasts.

South Tip

South Tip lies at the southernmost point of Racha Noi Island and is one of the area’s more challenging and rewarding dive sites. The site is relatively small and is dominated by impressive granite boulders, with the reef dropping dramatically into deeper water.

The northern section of the site sits at around 15 to 18 metres, while the seabed descends to more than 60 metres towards the south. On the western side, the granite slope is relatively gentle, while the eastern side is steeper and more exposed.

Hard and soft corals grow across the rocky formations, including fire corals and sea fans, adding colour and texture to the dramatic underwater landscape.

South Tip is not suitable for beginners or intermediate divers. Currents here can be strong, complex and sometimes extreme, with conditions changing quickly around the tip of the island.

Because of these challenging conditions, South Tip cannot always be included in the regular daily dive schedule. When conditions are suitable, however, experienced divers can enjoy an exhilarating dive in one of Racha Noi’s most exposed and spectacular locations.

Marine Life

The main attraction at South Tip is undoubtedly the possibility of encountering manta rays. These graceful giants are regularly seen in the area, with encounters particularly common between February and April.

The rocky reef also attracts large schools and individual surgeonfish, unicornfish, triggerfish and damselfish, while great barracuda are another regular sighting.

Leopard sharks are occasionally seen in the area, although encounters are less common.

With its dramatic granite formations, deep blue water, powerful currents, and regular manta ray encounters, South Tip is a dive for experienced divers looking for adventure and big-animal encounters.

Banana Bay

Banana Bay, on the eastern side of Racha Noi Island, is thought to take its name from the abundance of banana trees growing along the shore. Above and below the water, it is a relaxed and scenic dive site, with a gently sloping reef that offers plenty to explore.

The dive begins in a shallow, flat area between approximately 3 and 10 metres, making it particularly accessible for newer divers and an enjoyable place to explore at a leisurely pace. From there, the hard-coral reef gradually slopes down to around 25 to 30 metres.

Much of the reef is covered by extensive staghorn coral, interspersed with patches of fine, white sand. The contrast between the branching coral and sandy areas creates an attractive underwater landscape and provides shelter for a wide variety of marine life.

Marine Life

The staghorn coral is home to colourful fusiliers, triggerfish, butterflyfish, and basslets, which can often be seen moving above the reef.

The shallow sections are particularly interesting for spotting larger reef creatures. Keep an eye around the coral and rocks for giant moray eels, reef octopuses, black-and-white snappers, lionfish, and scorpionfish. Sea snakes may also be encountered as they move across the reef and sandy bottom.

For macro enthusiasts, the staghorn gardens are well worth exploring carefully. Nudibranchs can often be found crawling across the coral, offering plenty of opportunities for close-up photography.

And don’t forget to look away from the reef and into the blue water. Banana Bay is also a place where lucky divers may encounter manta rays passing through the area—an unforgettable sight when these graceful giants appear above the reef.

With its shallow coral gardens, gentle slopes, and varied marine life, Banana Bay is an easy-going dive site with the potential for some very special encounters.

Marina Rock

Marina Rock, on the western side of Racha Noi Island, is a dramatic granite dive site where large rock formations are covered in a rich variety of corals. Leather corals, sea fans, sea whips, fire corals, and hard corals such as pore corals create a colourful underwater landscape across the reef.

The dive can begin over the sandy bottom at around 18 metres, or closer to the southern side of the bay, where enormous granite boulders rise from the seabed and slope down to approximately 35 to 40 metres.

One of the highlights of Marina Rock is its network of swim-throughs. These passages wind between and through the granite formations, offering an exciting way to explore the reef while revealing different angles of the underwater landscape.

Marine Life

The coral-covered rocks attract a wide variety of reef fish, including parrotfish, snappers, angelfish, butterflyfish, and schools of neon fusiliers.

The sandy bottom is also worth exploring. Look for bluespotted stingrays resting on the sand and pairs of scissortail gobies hovering just above their burrows.

Take your time around the granite formations and inspect the corals and crevices for smaller creatures. Nudibranchs and pipefish can sometimes be found hiding among the reef, rewarding divers who slow down and look closely.

In the deeper blue water beyond the reef, there is always the possibility of a memorable encounter with a manta ray.

With its towering granite boulders, colourful corals, swim-throughs, and varied marine life, Marina Rock is a fascinating site for divers who enjoy exploring underwater topography as much as looking for marine life.

Racha Noi Bay

Located on the southeastern side of Racha Noi Island, Racha Noi Bay is easily recognised by the small islet just offshore. At low tide, a narrow sand ridge connecting the islet to the main island becomes visible, giving the bay its distinctive appearance.

The shallow coral gardens at the northern and southern ends of the bay are particularly well suited to snorkelling and relaxed shallow-water exploration. As the reef descends, the coral gradually gives way to a sandy bottom at around 12 metres.

Deeper sections reveal a completely different underwater landscape. Below approximately 30 metres, rocky formations are covered with impressive sea fans and sea whips, creating a dramatic backdrop and providing shelter for a variety of marine life.

Marine Life

Racha Noi Bay is known for its diverse marine life, with plenty to discover from the shallow coral gardens to the deeper rocky areas. Alongside the usual reef fish, divers may encounter scorpionfish, garden eels, eagle rays, and milkfish.

The sandy bottom is particularly rewarding for divers who enjoy searching for well-camouflaged creatures. Look carefully for cuttlefish, flounders, and pipefish, which can be remarkably difficult to spot against the seabed.

When conditions are calm, it is also worth looking away from the reef and into the deep blue water. Lucky divers may encounter larger pelagic species such as leopard sharks, manta rays, and, occasionally, whale sharks passing through the area.

With its shallow coral gardens, sandy slopes, dramatic deep-water formations, and diverse marine life, Racha Noi Bay offers a fascinating range of underwater environments in a single dive site.

My diving cruise with The Smiling Seahorse was absolutely fantastic from start to finish. Everything was extremely well organized and seamless, making the entire vacation completely stress-free and enjoyable. The crew was exceptional — professional, friendly, attentive, and always making sure everyone felt comfortable and safe. The food was amazing throughout the trip, with great variety and quality at every meal. The boat itself is excellent: very comfortable, well maintained, and thoughtfully designed for divers. The cabins are spacious and comfortable, and the common areas are very well organized, giving everyone plenty of space to relax between dives. What truly made the experience unforgettable was the incredible selection of dive spots. Every dive offered something special, with beautiful marine life, stunning coral reefs, and perfectly planned itineraries. Overall, this was a full enjoyment vacation and one of the best liveaboard experiences I’ve had. I highly recommend The Smiling Seahorse to anyone looking for a perfectly organized diving adventure with a fantastic crew and unforgettable diving.

Another vote for the Smiling Seahorse - it's a very good boat. Purpose built for serious diving, the thought and care put into it by its owner and crew really shows. Everything you need is available, easy to access, well maintained and functional, without anything extraneous or funky. There is a devotion to diving, to underwater photography, to the marine life, to the history and natural history of the Similan Islands and Burma, to the guest experience and developing our skills. Our group did the week-long South to North Andaman Sea trip in January 2026, and each day was better than the one before. The diving is exceptional, with healthy corals and masses and masses of fish, even before we got to the climax of Richelieu Rock. They include an black water dive on each trip, a truly unique opportunity. We received tremendous support from the dive guides and the crew alike, who gracefully and respectfully accommodated everyone's needs. Even the little things - one of the deck crew noticed that the little strap connecting the dust cap to my regulator was close to breaking off and offered to repair it. He did a beautiful job and I'll be reminded of his generosity and kindness each time I dive that reg. Our guide, James, has years of experience, like many masters, conveyed his knowledge with simplicity and clarity (and humor - whew!). I became a better diver following his example. I keep remembering the happy anticipation of standing at the stern, all kitted up, waiting for the captain's signal to jump. Next trip - Burma. The cabins are simple and comfortable, although you may want to bring a pad if you're not a fan of firm beds. A/C and hot water in each cabin - all good. Everyone in our group, from the experts with many thousands of dives to the recently certified, to a couple of non-diving spouses, loved the Smiling Seahorse!

We had an amazing time on the Smiling Seahorse liveaboard in Thailand. Everything was well organized, relaxed, and very professional. Our dive guide Julien was fantastic. He showed us beautiful dive sites and even pointed out tiny nudibranchs we would never have seen ourselves. His eye for detail made every dive special. The food was excellent, and the crew was incredibly friendly and helpful, especially when assisting with dive gear. Overall, a wonderful experience – It was our 2nd trip and we will definitely come again!

An Unforgettable Week Underwater! I just wrapped up a phenomenal week-long liveaboard trip in the Similan Islands with The Smiling Seahorse team, and I cannot recommend them enough. The dives were absolutely gorgeous, but what really set the experience apart was Julian’s amazing spotting skills—he has an incredible eye and made sure we didn't miss a thing. The entire crew was attentive, professional, and always right there to assist with all of our needs, making the whole week completely seamless. On top of the world-class diving, the food was fantastic. Everything was incredibly tasty, and they offered a great variety of dishes that really hit the spot after a long day in the water. Five stars across the board—if you're looking for a top-tier liveaboard operation, this is the team to go with!

I went for a 9 day dive safari in Myanmar, the mergui archipelago, with the smiling seahorse. One of the unique experiences I had. My first (and second and third) Blackwater dive, dives I will never forget. The staff are wonderful, the dive guides are amazing, they actually care and put in a lot of extra effort and the ship crew were helpful and nice. I dove with Julian, the dive master, who I would dive with anywhere anytime, and we enjoyed the presence of camille, the owner, who lit up the place with her positive energies. I've been on fancier boats, but I enjoyed this one much better.

Safe, clean, friendly staff always willing to help, easy on and off the boat, good dive sites. Guides are awesome. The dive crew very accommodating. Nice camera room. Keep the same tank entire trip. Some sites we went in small groups in a dingy. The return the dingy would slowly pull you back. Thankful we did nit have to struggle getting back in the dingy Some times we would just float back to the boat. We were divided into groups so everyone wasn’t getting ready at the same time. Plenty of food and snacks. Only complaint is the chairs and beds are hard as cement. Compared to the good stuff that was nothing. I would for sure go again.

I just returned from a week-long liveaboard with the club, and the experience was simply outstanding. The entire team demonstrated high professionalism throughout, with in-depth safety briefings and modern, well-maintained equipment. A special thanks to our amazing dive guides: James, Velika, Katie, and Mint. Each of them brought great energy and uncompromising expertise. Thanks to them, we felt in safe hands during every dive, and they knew exactly how to lead us to the most beautiful spots in the pristine sites we visited. The boat was very comfortable, and the excellent food between dives rounded out the experience perfectly. This is without a doubt a top-tier diving club, and I highly recommend it to anyone looking for a week of peace and world-class diving!"

An outstanding liveaboard experience from start to finish. The hospitality on The Smiling Seahorse is truly exceptional — warm, attentive, and genuine, making you feel welcome and taken care of at every moment. The dive sites were beautiful and well chosen, offering a great variety and excellent conditions. Each dive felt thoughtfully planned to maximize both safety and enjoyment. What really sets this liveaboard apart is the extraordinary professionalism of the crew and dive instructors. Their experience, calm approach, and attention to detail were evident throughout the trip. Briefings were clear and thorough, underwater guidance was excellent, and safety was always the top priority — without ever taking away from the fun. Highly recommended for anyone looking for high-quality diving combined with top-level service and professionalism. I would gladly dive with them again.

Best scuba diving Safari in Thailand These guys are incredible! 7 days of diving from the south to the north of the Andaman Sea. The staff are incredibly helpful and the food and atmosphere was great. Special thanks to Velika, our guide, that showed us many sea creatures from the micro (picachu) to the large (white tip shark). It was an adventure! Highly recommended.

Wonderful experience with the Smiling Seahorse After 9 wonderful days of a diving safari in Myanmar on the Smiling Seahorse liveaboard, I have to say that it’s been a long time since I’ve come across people who are so professional at what they do. The dive guide team is top notch! The crew that takes care of the boat and the diving equipment is extremely professional, always thinking about every single detail and showing endless care for the guests. The boat feels very homely and warm, and it’s especially well suited for underwater photographers. Simply pure pleasure incredible diving, warmth, and love for the guests both above and below the water. Oren Kidron

Amazing company to go diving with. They picked us up at Koh Phayam even though they are based in Ranong, and helped us organize our transport onwards from Ranong after the trip. James organizes everything with a steady hand and a twinkle in the eye. You will not be bored during briefings on the smiling sea horse. Our guide, Veli Ka, was just amazing as well. So full of knowledge and safe and fun to dive with. All the crew were really nice - seems like a great work environment. The boat itself was really comfortable with a big lounge, sun deck, AC rooms with private bathrooms. Not crowded at all. The food was mouth watering as well. 5 stars!

So, get ready to strap on your scuba gear and dive into the adventure of a lifetime.

Shark Point

Shark Point dive site is a true gem of the Andaman Sea. Named for the frequent sightings of Leopard Sharks in the area, locals know it as Hin Mu Sang. Located just 27 km from Phuket, it’s situated near the Anemone Reef and King Cruiser wreck, and is made up of three main pinnacles.

This site boasts the most diverse range of fish and corals among all Phuket and Phi Phi Islands dive sites. Each pinnacle is spaced 15-20 meters apart, and is adorned with stunning purple and pink soft corals, as well as beds of table coral, staghorn coral, coral head, and huge sea fans. With an average depth of 15 meters and a maximum of 30 meters, there’s plenty to explore.

Anemone Reef

Beneath the surface of the Andaman Sea lies a mesmerizing underwater wonderland at Anemone Reef. Submerged beneath the waves, this pinnacle rises to 5 meters , earning its Thai name “Hin Jom”. Densely adorned with sea anemones, the pinnacle offers an awe-inspiring vista of the sea’s own living carpet.

With a north-south orientation and a sloped channel on the southern part, Anemone Reef boasts a depth range of 5 to 30 meters. As a result of the multitude, quality, and variety of marine life that resides amidst the beautiful coral and sea fans that adorn the pinnacle, Anemone Reef is the favoured site for both divers and photographers alike.

Marine Life  

Anemone Reef’s marine life is a true feast for divers and photographers alike. Anemonefish and clownfish are abundant and add a splash of color to the already vibrant environment. The pinnacle is also home to big schools of snapper that cloud the area, creating an impressive spectacle. Along with these, you may spot yellowtail barracuda, groupers, oriental sweetlips, juvenile harlequin sweetlips, scorpionfish, and soldierfish that dance among the corals and crevices. Leopard Sharks, which may have escaped from the nearby famous dive sites, can also make a surprise appearance.
For those who love small critters, Anemone Reef has its share of exciting finds. Keep an eye out for tiger-tail seahorses and ornate ghost pipefish that can be found in the shallow areas near the mooring line. Nudibranchs and even anglerfish have also been known to make an appearance in this stunning dive site.

King Cruiser Wreck

The King Cruiser Wreck: An Advanced Diver’s Delight

The King Cruiser Wreck is a fascinating dive site with an interesting history. Originally a car ferry, the boat sank in 1997 while carrying only foot passengers. Thankfully, there was no loss of life, as the boat sank slowly and several dive boats were around the area to help. The wreck now sits upright on its twin hulls, forming an artificial reef that attracts an abundance of marine life.
At 85 meters long, the wreck is not small, earning it the nickname “Thaitanic.” It’s worth diving more than once, as it’s impossible to see everything in just one dive. The maximum depth is over 30 meters, making it suitable only for advanced certified divers. The top of the wreck is at around 16 meters depth and is marked by a buoy. Divers should use the line attached near the front of the boat to descend and ascend safely.
While the car deck area was accessible in the first few years after the sinking, it has since collapsed, and penetration of the wreck is now prohibited.

Marine life  

The area surrounding the King Cruiser wreck is teeming with marine life, making it a must-see for any diver. Schools of snappers, barracuda, fusiliers, rabbitfish and goatfish are so abundant that they’ve become a bigger attraction than the wreck itself! With good visibility, the spectacle is simply breathtaking.
As you venture closer to the wreck, you may encounter bamboo or leopard sharks, and even the occasional turtle. The wreck also serves as a landmark for nudibranchs, so keep your eyes peeled for these colourful creatures during your dive.
However, it’s crucial for divers to exercise caution and avoid touching anything or putting their hands on the wreck. The King Cruiser have become an artificial reef full of thriving marine life, and it’s important to preserve and protect its delicate ecosystem.
Overall, the King Cruiser Wreck is a unique dive site that offers a glimpse into the past while providing a home for a thriving community of marine life. It’s a must-visit destination for advanced divers looking for a new challenge.

Koh Dok Mai, a diver's paradise...

Despite its name, Koh Doc Mai or Flower Island has no flowers to speak of, but that doesn’t make it any less of a wonder to explore. This stunning limestone island stretches vertically down to 30 meters, creating an impressive wall that attracts divers from all over. While the west side boasts a shallow reef teeming with hard coral and marine life, it’s the east wall that truly captivates.
The wall is riddled with cracks, crevices, and caverns, offering endless opportunities to discover hidden treasures. One of the most popular spots is a large cave and a small cave, both found on the east side of the island. While the small cave is narrow and long, it’s worth exploring only for certified cavern divers.
Unfortunately, Koh Doc Mai is uninhabitable and inaccessible, so landing on the island is impossible. But that doesn’t diminish the beauty of its underwater world. This is a diver’s paradise, with plenty of marine life. So, if you’re looking for an unforgettable diving experience, add Koh Doc Mai to your list!

Marine life  

A good variety of small creatures make this site a favourite for scuba diving activities. Tiger-tale seahorse, ornate ghost pipefish and anglerfish are among the species frequently found along the wall dive slowly and check crevices in the wall or the sea fans, and you may spot them when they move.
The walls are also a paradise for macro photographers, as colourful nudibranchs, flatworms, tiny white eyes morays and group of 10 or more dancing shrimp are guaranteed to make an appearance. Do examine cracks and small crevices for giant morays, and enjoy the schools of yellow line snapper, trevally and fusiliers that usually swim along the wall.
For those interested in bigger fish, look at the blue for great barracuda and leopard shark may also catch a few winks at the bottom of the wall.

Homerun Reef is a popular last dive of the day, as it offers a stunning dive along the north side of Racha Yai Island, leading back towards Chalong Bay. The site is suitable for all levels of divers, including beginners, but can be challenging at times due to the strong currents heading north.

Named after the banana trees that line the bay, it boasts powdery white sands, turquoise waters, and lush greenery that make it a true tropical paradise.

South Tip

Located on the southernmost tip of Racha Noi, South Tip is renowned for being the best site in the Phuket day trip area to witness the majestic Manta rays. It is also the site we choose to dive on the last day of our dive cruises when we go from Similan to Phuket.
South Tip is quite a small site dominated by large granite boulders that start at around 14 metres and go beyond 40 metres. This site is prone to strong currents, and there is no protection from the island, which means waves can be an issue when the sea is not at its calmest. If the sea is a bit wavy,  it may be best to relocate it to the nearby Racha Noi Bay.

Due to the difficulty of the dive and strong currents, this site is recommended for experienced and advanced divers only. But the rewards are worth it, especially during the winter months, when Manta rays sightings are most common.

The rocky reef is covered with soft corals, sea whips, and an array of marine life, including unicorn fish, surgeon fish, and the occasional school of Chevron Barracuda.

Racha Noi Bay

Racha Noi Bay is a picturesque and stunning dive site located on the southeastern side of Racha Noi island. Although it is farther from Phuket, it is worth the extra boat ride for the beautiful scenery and crystal-clear waters.
This dive site is ideal for novice divers as it has a large soft sand plateau and a gradual slope that leads to a maximum depth of 35 meters. Additionally, there is a small rocky island to the south that makes for an interesting attraction during the dive.
​
Advanced divers can explore the rocky reef that runs along the eastern side of the bay, but be cautious of strong currents that can pull you southward. Some of the best drift dives in the area can be found here.

Racha Noi Bay is also an excellent location for spotting pelagic species, including the ever-popular manta rays. Though it is not as well-known as the nearby South Tip dive site, it is the closest location to it, making it an ideal spot for novice divers while their more experienced counterparts explore South Tip.
​
Overall, Racha Noi Bay is a must-visit dive site for any diving enthusiast seeking an unforgettable underwater experience in the clear waters surrounding Phuket.

Marita's Rock and Marina Bay

Marita’s Rock and Marina Bay are two stunning dive sites located close to each other, making it possible to explore both in one dive. The dive sites are adorned with soft corals and Gorgonian Sea Fans that provide a vibrant and colorful underwater scenery, with visibility ranging from 10-30+ meters. The impressive boulder formations found here create opportunities for swim-throughs, canyons, and small caverns to explore.

While the current inside Marina Bay is typically mild, it can be very strong outside the bay, especially at Marita’s Rock. As such, Marita’s Rock is recommended for experienced divers only, due to its strong currents. Racha Noi is the last dive site before the Andaman Sea, which means that the dive sites around the island start to get deep. This makes for some great opportunities to spot large pelagic fish such as Tuna, Barracuda, and Trevallies.

Manta Rays are frequently spotted at both dive sites, along with occasional sightings of Whale Sharks, Blacktip and Whitetip Reef Sharks. Keep your eyes open and be prepared for an incredible underwater adventure
