Last trip of the season in surin and similan islands

Season Finale aboard MV Smiling Seahorse: ​
​Best of Similan & Surin – April 30 to May 7, 2025

Our final voyage of the season began with sunshine and calm seas as we welcomed our lovely guests from France, Austria and Koh Tao aboard the MV Smiling Seahorse. Departing from Phuket’s Marine Charter Pier, our 8-day journey would take us through the heart of Thailand’s most iconic dive destinations--Similan and Surin National Parks.
​

These two marine parks are crown jewels of the Andaman Sea. The Similan Islands, renowned for their dramatic granite boulders, swim-throughs, and endless schools of fusiliers, offer breathtaking topography and pelagic action. Further north, Surin National Park is home to colorful coral gardens, rare macro life, and the legendary Richelieu Rock—one of the best dive sites in Southeast Asia.

Day 1: Similan Beginnings

We began with a check dive at Shark Fin Reef, where thousands of juvenile scissortail and yellowback fusiliers blanketed the water column in glimmering silver. Wrasses and rabbitfish busied themselves around the rocks, while starry dragonets tiptoed across sandy patches. Giant and bluefin trevallies flashed by, and a hawksbill turtle glided over the reef. Batfish and a great barracuda patrolled the boulders below.
At Boulder City, the massive sea fans created a forest beneath the sea. Squat shrimps and Durban dancing shrimps swayed with the current, while giant groupers hid in the crevices. Fusiliers flowed like rivers, and we were treated to a turtle sighting once more.
Statue Bay and Hideaway revealed the wreck and stunning hard coral formations shaped like layered flowers. Schools of yellowback fusiliers swirled around us, and we found a tiny juvenile sweetlips bobbing near the coral—an adorable reminder of reef life’s fragility. A giant moray peeked from his lair while an octopus changed color before our eyes.
We ended the day with a peaceful night dive at West of Eden, where the coral glowed under our lights and crustaceans crept out into the night.

​Day 2: Pinnacles and Swim-Throughs

At West of Eden again in the morning light, a hawksbill turtle passed by gently as  a pipehorse and multibar pipefish darted through soft corals. Blue dragons and oriental sweetlips brightened the boulders below, and a curious sea snake slithered through the reef.
Elephant Head Rock gave us both drama and beauty—giant sea fans waved beside the towering swim-throughs. Blacktip sharks cruised the deep, while batfish posed at safety stop depth. Schools of snappers, scissortail fusiliers, and trevallies zipped by. A pregnant pufferfish hovered in the current, accompanied by her always-alert boxfish companions.
The night dive at Donald Duck Bay was full of life: spiny lobsters, scallops pulsing open and shut, and a nail sea star caught mid-feeding.

​Day 3: Heading North

At North Point, we swam among oriental and harlequin sweetlips, longnose emperors, and more fusiliers than we could count. Giant seafans fanned gently in the current. Then at Three Trees, garden eels wavered in the sand while blue-spotted stingrays zipped by. Barrel sponges lined the seafloor, home to gobies and blennies, while yellowband fusiliers clouded the reef above.
En route to Koh Bon, we were met by a pod of dolphins—an incredible mid-ocean surprise.
At Koh Bon Ridge and Bay, we spotted a baby blacktip shark, potato groupers resting on the reef, and schools of longnose emperors hunting alongside giant sweetlips, redtooth triggerfish, coral groupers, and flocks of masked rabbitfish.
That night, the blackwater dive offered up the strange and wonderful: a blue-ring octopus, baby jacks hiding in salp chains, squid, and translucent larval crabs drifting in the dark.

​Day 4: Barracudas and Batfish

Koh Bon Pinnacle did not disappoint. Massive schools of fusiliers swirled around us as a great barracuda sat motionless at a cleaning station. Oriental sweetlips mingled with batfish and cleaner shrimps in every nook and cranny. A solitary eagle ray glided silently past us, giving the entire scene a dreamlike touch.
At Koh Tachai, the reef exploded with color. Blacktip sharks circled the pinnacle. Schools of barracuda glimmered beneath the sun’s rays. Bigeye jacks formed a living tornado, while lobsters filled every rocky crevice. Between enormous orange seafans and pink coral towers, we admired juvenile angelfish, bicolor cleaner wrasses, yellowtail wrasses, and tiny jewel fairy basslets fluttering among the purple soft corals. The third pinnacle glowed during our final dive, with batfish forming a stately procession across the reef top.

​Day 5: Surin's Soft Side

We reached Rainbow Rock/Yellow Rock and found the colors mesmerizing: soft coral in every hue—yellow, pink, blue, and violet. A resting Jenkins ray sat camouflaged on the sand, and bluefin trevallies darted past schools of silver sweetlips. Hawksbill turtles grazed on sponge, while pipefish and nudibranchs (including a striking purple one) crept along the coral wall.
At Torinla Pinnacle, we found two elegant black ornate ghost pipefish dancing among the gorgonians. A baby white-tip reef shark rested beneath a ledge, and a giant pufferfish lazily floated by with its ever-present remora. Among the coral, a tiny Thecacera—or pikachu nudibranch—entertained macro photographers.

Days 6 & 7: Richelieu Rock Grande Finale

We saved the best for last. Richelieu Rock, a dive site that truly never ceases to amaze, gave us everything. Visibility was perfect. Glassfish, juvenile fusiliers, and baitballs were being chased in every direction by emperors, trevallies, rainbow runners, and snappers. It was chaos in the best possible way. Chevron and yellowtail barracudas swept in and out, and trumpetfish hunted vertically alongside scorpionfish hiding in coral heads.

​In between the drama, macro life was thriving: the smallest harlequin shrimp we’ve ever seen balanced on a sea star, tiger tail seahorses swayed with the current, and ghost pipefish hovered delicately in their shadows. Moray eels—fimbriated, honeycomb, and giant—peered out from coral alcoves. We found butterflyfish, damsels guarding eggs, and even an elusive mimic blenny poking from the rubble.
These last dives were the perfect conclusion to our season—a celebration of life, color, and the unmatched magic of the Andaman Sea.
As we returned to Ranong, the sun dipped behind the mangroves and the MV Smiling Seahorse entered her summer rest. But in our minds, the ocean is still alive with swirling fish, curious sharks, and coral gardens dancing in the current.
Until next season, happy bubbles from all of us aboard!​

North and South Andaman Adventure in Thailand trip report

Thailand's Andaman Sea: North and South – April 21–28, 2025

Exploring Thailand’s Underwater National Treasures
As the sun rose over Ranong, we welcomed an enthusiastic group of divers from the USA, France, Brasil, and Switzerland aboard the MV Smiling Seahorse. Our journey would take us through some of Thailand’s most iconic national parks—from Surin and Similan to Lanta and Tarutao—each with its own unique seascape and underwater wonders. Spirits were high as we set a course for the famed Surin Islands to begin our underwater adventure. All pictures on this blogpost were taken by our distinguished guests.

Day 1: Surin National Park – A Colorful Beginnin

We started gently at Koh Chi with a smooth check dive. A green turtle greeted us calmly near the surface, while beneath us a flurry of life unfolded. Schools of fusiliers flashed by in silver and gold, flanked by lionfish lurking near coral outcrops. A flabellina nudibranch caught our eye, soon followed by a brilliant Thecacera, better known as the pikachu nudibranch. Moray eels slithered through the cracks, and a stonefish lay well camouflaged in the sand.

​At Richelieu Rock, the action exploded in all directions. Rainbow runners swept past in schools, chased by jackfish and trevallies. A longface emperor patrolled the reef edge while a ghost pipefish hovered in the current. We marveled at a delicate tiger tail seahorse wrapped around a whip coral and delighted in sightings of harlequin shrimp, white-eyed and giant morays, and a baby mimic octopus dancing across the sand.
Anemone crabs, mackerel, tuna, and hairy shrimp all made appearances, with dogtooth tuna cruising in the distance and clouds of barracudas circling overhead.

Our night dive on Richelieu Rock revealed the reef's secret nocturnal side. Among the crustaceans were banded coral shrimps, squat lobsters, transparent cleaner shrimps, and an energetic boxer shrimp. Decorator spider crabs crept slowly across the corals, while a bold red crab was caught pulling a soft coral free—redecorating the reef, it seemed, in its own way. A trumpetfish patrolled the shallows as scorpionfish hunted under the beams of our torches.

​Day 2: Similan National Park – Granite Giants and Pelagic Glory

At Koh Tachai Pinnacle, the visibility stretched on forever, revealing a stunning cast of marine life. Giant groupers peered out from overhangs, and bluefin trevallies streaked past in hot pursuit of silvery baitballs. Blacktip sharks cruised the periphery, while massive schools of yellowback and blueback fusiliers lit up the water. We also admired pickhandle barracudas, giant snappers, and dogtooth tuna patrolling in the blue, and couldn’t miss the clown triggerfish darting between boulders. Lobsters peeked from crevices and surgeonfish grazed along the reef walls.
At Koh Bon, we were lucky enough to spot a whitetip reef shark gliding gracefully across the reef, followed by a school of batfish shadowing us from a respectful distance. Giant trevallies patrolled the deeper sections while groups of parrotfish crunched away at the reef. In the coral gardens, butterflyfish, wrasses, and Moorish idols added dazzling detail to the scene.
​
Our blackwater dive that night was a dreamlike journey into the abyss. We were met by strange and mesmerizing creatures: larval flounders fluttering in the current, translucent baby squids, flying gurnards spreading their wing-like fins, and a baby sea elephant drifting gently by. Even a juvenile mantis shrimp made a curious appearance.

​Day 3: Similan National Park – Rays, Reefs, and Swim-Throughs

Three Trees delivered calm water and stunning white sand patches covered in garden eels. A porcupine stingray and blue-spotted ray swept by, while above us schools of fusiliers and snappers moved in synchronized waves. Curious trumpetfish hovered and gobies danced along the sandy slopes.
Elephant Head Rock was majestic as always. We drifted through its cavernous swim-throughs, surrounded by walls adorned with giant sea fans and hunting giant moray eels. A white-tip shark slipped by, and above us an eagle ray soared across the sunbeams. We caught sight of a mature yellow boxfish before it tucked into a crevice, while blue-lined groupers and bannerfish hovered near the edges of the boulders.
At West of Eden, a vibrant coral garden greeted us, bursting with color and activity. Fusiliers, parrotfish, groupers, and an array of surgeonfish filled the reef. A hawksbill turtle paddled calmly overhead, and a bold eagle ray buzzed us in the blue. Chromodoris nudibranchs and flabellinas dotted the walls, while a large tuna charged past at the end of the dive.

We spent the entire day diving the twin giants of the South: Hin Daeng and Hin Muang. The reef was electric—ghost pipefish floated in the current, while juvenile clown triggerfish and sweetlips played along the reef. Schools of  rainbow runners swept by like silver bullets.
​
​We spotted several Wahoos, giant trevallies and bluefin trevallies on the hunt, and even found a massive clown frogfish and hairy shrimps expertly camouflaged on the wall as well as a mantis shrimp carrying its eggs!

The sunset dive was full of movement and macro life. Helmet crabs and decorator crabs scuttled across the reef while zebra moray eels and common morays hunted along the slopes. Nudibranchs—chromodoris fidelis, annulata, risbecia, and geminus—dotted the rocks like confetti, with bornella anguilla curling through the soft corals.

​Day 5: Koh Tarutao National Park – Reef Riches and Tropical Surprises

​At 8 Mile, action unfolded fast. Jackfish surged through schools of damsels, while great barracudas enjoyed a spa treatment at a midwater cleaning station. Stonefish crouched on coral heads, hiding in plain sight, while sweetlips and snappers pulsed in the current. Surgeonfish and groupers mingled along the reef, flanked by bannerfish and goatfish.

At Steps, we enjoyed sightings of coral catsharks, triggerfish, angelfish, and a group of blackspot wrasses working over the coral. At Stonehenge, a devil scorpionfish waited in ambush, while a pair of cuttlefish hovered over the sand. We saw blue dragons clinging to overhangs, as well as a mix of tomato, saddleback, and false clown anemonefish.

At Koh Taru, baby yellow fusiliers filled the reef, flashing like lightning. A baby yellow boxfish stole hearts with its wobbling swim, while a large star puffer looked on with sleepy eyes. Indian Ocean walkman scorpionfish and banded pipefish made rare appearances to round off the day.

Day 6: A Final Sweep Through the South Andaman

Back at Hin Daeng, batfish and fusiliers welcomed us again, with chromodoris nudibranchs adding pops of color. Hin Muang gave us a fantastic encounter with a clown frogfish, alongside a powerful school of wahoo and a mix of giant and bigeye trevallies.
​

At Koh Haa’s Cathedral, the ethereal beams of sunlight filtering through the swim-through lit up clouds of glassfish, flabellinas, and chromodoris albopunctata. In the Chimney, we added wrasses, gobies, damselfish, and a handful of skunk anemonefish to our growing species list.

At Shark Point, our last dive brought us past massive barrel sponges teeming with life. Schools of fusiliers, chromodoris annulata, and a sly scorpionfish shared the reef with sand-colored flounders and the ever-graceful bannerfish. A pair of butterflyfish saw us off as we began our slow ascent.
​As we returned to Phuket, the boat was buzzing with stories, laughter, and glowing memories. From turtles and seahorses to blackwater aliens and reef giants, this trip through Thailand’s best dive sites had truly lived up to its name.
Koh Bida Nok delivered a dramatic last day. A blacktip reef shark cruised by as a yellowtail seahorse clung to coral nearby. A banded sea snake slipped between rocks while cuttlefish hovered in the blue.

For this Whale Shark Expedition, we were thrilled to welcome aboard the M/V Smiling Seahorse a diverse group of divers from Romania, France, the USA, and Australia. Adding to the excitement, we were joined by Josh Johnson, a marine biologist specializing in whale shark conservation. Based in Koh Tao, Josh is a graduate of the University of Plymouth’s BSc Ocean Science and Marine Conservation program.

Josh shared fascinating insights into whale shark biology, ecology, and conservation:
“Although they are the largest fish in the world, they remain one of the least studied sharks globally, especially in Thai waters. With so much still to learn about them, it is crucial to explore new methods for monitoring their migration patterns and feeding hotspots. This allows us to implement the best conservation strategies to protect these gentle giants.”

Setting sail from Phuket on March 23rd, we first explored Koh Lanta National Park and Koh Tarutao National Park for three days before heading north to discover the wonders of the Similan and Surin National Parks. Each of these marine sanctuaries is a jewel of the Andaman Sea, boasting a unique blend of stunning underwater landscapes, thriving marine life, and vibrant coral ecosystems.
    •    Koh Lanta National Park is renowned for its dramatic limestone formations and rich marine biodiversity.
    •    Koh Tarutao, the largest national park in the Andaman, remains a pristine paradise with spectacular reefs and abundant pelagic life.
    •    The Similan Islands, world-famous for their breathtaking granite boulders and crystal-clear waters, offer incredible diving experiences with flourishing coral gardens and deep pinnacles.
    •    Surin National Park, home to the legendary Richelieu Rock, features one of Thailand’s most spectacular dive sites, teeming with marine life and a prime location for large pelagic encounters.

This unforgettable expedition combined breathtaking scenery, exceptional dives, and invaluable knowledge, leaving us all with a deeper appreciation for whale sharks and their conservation.

Day 1 – Koh Lanta National Park

Our check dive at Koh Ha Lagoon provided a smooth and scenic introduction to the trip. Among the coral bommies, we spotted a perfectly camouflaged Ornate Ghost Pipefish, swaying gently with the current, while a curious Coral Grouper patrolled its reef territory. Schools of Yellowback Fusiliers darted through the water, accompanied by striking Emperor Angelfish, adding bursts of vibrant color to the scene.

In the afternoon and evening, we explored Hin Mueang and Hin Daeng, where the reefs were teeming with life. A Clown Frogfish, perfectly still and expertly blended into a sponge, caught our attention. Nearby, pairs of Ornate Ghost Pipefish hovered delicately in the water. Overhead, Red-Toothed Triggerfish swirled in mesmerizing formations, while Giant Trevallies patrolled the reef in search of prey. Schools of Rainbow Runners flashed by in unison, and among the hard corals, we admired a striking Peacock Grouper and a Blue-Barred Parrotfish lazily grazing.

Day 2 – Koh Tarutao National Park

​The morning began at Hin Paad Mile, where Giant Trevallies moved in synchronized schools, their silver bodies flashing as they sliced through the water. Beneath a coral ledge, a massive Potato Grouper rested, watching us with a slow, deliberate gaze. Around us, schools of Bengal Snappers and Blue-and-Gold Fusiliers shimmered, creating a breathtaking display of color and motion.

At Stonehenge, the highlight was a perfectly camouflaged Tigertail Seahorse, delicately gripping onto a sea fan. Nearby, an Indian Walkman lay in wait on the sand, its intricate fins blending seamlessly with the ocean floor.

Day 4 – Similan Islands, Similan National Park

Our dive at Shark Fin Reef welcomed us with a breathtaking spectacle of marine life—schools of Lunar Fusiliers swirled around us in a dazzling display, while Parrotfish crunched noisily on the reef, shaping the underwater landscape with every bite.

At West of Eden, we encountered a playful Octopus, shifting colors in a mesmerizing dance before our eyes. A Rock Mover Wrasse skillfully flipped coral rubble in search of hidden prey, while a Psychedelic Batwing Seaslug nestled discreetly in a crevice, adding a splash of vibrant color to the reef.

At Elephant Head Rock, the current carried us effortlessly past Giant Trevallies hunting in the blue, while a pair of Sweetlips hovered serenely beneath an overhang. In a sandy patch, a White Tip Reef Shark lay motionless, completely undisturbed by our presence.

We ended the day with a captivating night dive at Turtle Rock, where Basket Stars unfurled their intricate arms to feed, and Decorator Crabs, masterfully disguised with sponges and algae, scuttled stealthily across the seabed.

Day 5 – Similan Islands, Similan National Park

Xmas Point welcomed us with a vibrant display of reef life—from the dazzling flashes of Blue Striped Snappers to the sleek, steady glide of a Barracuda lurking in the distance.

At 3 Trees, a Blue Spotted Stingray lay half-buried in the sand, perfectly camouflaged, while a massive Potato Grouper loomed near the coral formations, surveying its domain.

Meanwhile, Koh Bon Pinnacle and West Ridge were alive with movement, as schools of Rainbow Runners and Longnosed Emperors wove effortlessly through the currents, creating a mesmerizing underwater ballet.

Days 7 & 8 – Surin National Park

Our final two days at Richelieu Rock were nothing short of spectacular. The site was teeming with life--Ornate Ghost Pipefish hovered gracefully among feather stars, Tigertail Seahorses clung to delicate sea whips, and Porcelain Crabs filtered plankton with meticulous precision. Banded Stick Pipefish wove through the reef, while Big Eye Trevallies and Giant Trevallies darted back and forth in a relentless hunting frenzy.

In the blue, schools of Barracudas hung motionless, suspended in perfect formation. We were mesmerized by a vast mixed school of Rainbow Runners, Emperors, and Big Eye Trevallies, moving in unison like a single, fluid entity. Red Snappers lurked near the coral formations, adding the final flourish to an already unforgettable experience.

As we sailed back to Ranong, the excitement and memories of the trip lingered among our group. The Whale Shark Expedition had given us not only breathtaking encounters with Thailand’s marine giants but also a deeper appreciation for the intricate beauty of the Andaman Sea’s underwater world.

Until next time, we carry with us the wonders of the deep and the hope for future encounters with the gentle giants we strive to protect.

​Day 6: Richelieu Rock – A Spectacular Finale

Our final dives at Richelieu Rock were the perfect ending to an already fantastic trip. The ornate ghost pipefish were back, adding an element of mystery to the site. A massive gang of giant trevally, golden trevally, longnose emperor, and rainbow runners formed a hunting frenzy over the reef. Schools of bigeye trevally created mesmerizing tornado-like formations, while tomato anemonefish hovered protectively over their eggs. A giant marble grouper lingered near a crevice, and a stunning blue dragon nudibranch was spotted among the soft corals.

Wonderful to welcome this great Dive club from the USA in Thai Waters!

Our latest adventure took us on an unforgettable journey through the Andaman Sea, welcoming 16 enthusiastic divers from a US diving club lead by a return adventurer: Toby. Setting sail from Ranong on the evening of February 9th, we embarked on a week-long liveaboard trip exploring Thailand’s most famous dive sites, from Surin and Similan Islands to Koh Lanta and Koh Lipe National Parks. With crystal-clear waters, thriving marine life, and even a rare sighting of a blue marlin, this was a trip to remember!

Day 1: Surin Islands & Richelieu Rock – A Vibrant Start 

Our adventure began with a check dive at Koh Chi, a serene site within Surin Islands National Park. Calm waters and over 30 meters of visibility set the perfect stage for the trip. We spotted blue-spotted stingrays, parrotfish, fusiliers, moray eels, and butterflyfish as we explored the site’s diverse marine life.
Next, we completed three exhilarating dives at Richelieu Rock, Thailand’s most iconic dive site. This world-renowned location was teeming with life--giant schools of bigeye trevally, emperor fish, rainbow runners, barracudas, and batfish at the cleaning station. The croissant-shaped pinnacle, covered in soft corals, giant sea fans, and vibrant anemones, provided the perfect habitat for clownfish with their eggs, dancing shrimp, and porcelain crabs. Franck got to photograph a cardinal fish carrying its eggs in its mouth!

Day 2: Koh Tachai & Koh Bon : Strong Currents, Big Rewards​

We kicked off Day 2 with an adrenaline-pumping dive at Koh Tachai Pinnacle. The strong current made for a challenging dive but rewarded us with an explosion of marine activity--huge schools of barracuda, tomato groupers, surgeonfish, snappers, fusiliers, batfish, and lobsters nesting in bommie corals.

Our third dive at Koh Bon Pinnacle was spectacular. With crystal-clear visibility and no current, we fully enjoyed the deep pinnacle, enveloped by dense schools of yellow snappers and massive batfish.

For our final dive of the day, we embarked on a blackwater dive, descending into the pitch-black depths over 80 meters of open ocean. Floating in the darkness, we encountered larval and post-larval fish, bulb squid, moray eels, flounders, mantis shrimp, snake blennies, and countless other deep-sea critters.

Day 3: Similan Islands – Boulders & Swim-Throughs

Our first dive at Three Trees took us through deep granite boulders covered in soft and hard corals. Among the highlights were blue-spotted stingrays, coral groupers, snappers, and fusiliers.
Next, we explored Elephant Head Rock, a diver’s playground filled with swim-throughs and tunnels among massive boulders. We encountered ribbon eels, octopuses, and giant trevallies hunting in the blue.
Our final dive of the day at West of Eden was a treat for macro lovers. This vibrant hard coral reef was home to turtles, seamoths, bluefin trevallies, and juvenile rock-moving wrasses.

Day 4: Hin Daeng & Hin Muang – Koh Lanta National Park

Diving at Hin Daeng and Hin Muang was nothing short of magical. These remote pinnacles, adorned with red and purple soft corals, were bursting with marine life. We encountered red-toothed triggerfish, milkfish, potato groupers, African pompanos, and bigeye and giant trevallies.
For macro enthusiasts, the highlights included two pairs of ghost pipefish, nudibranchs, juvenile emperor angelfish, and a rare juvenile clown triggerfish.

Day 5: Koh Lipe & 8 Mile Rock – Hunting Trevallies & a Surprise Visitor
Our morning dives at 8 Mile Rock provided perfect conditions, excellent visibility, and no current. The dive site was buzzing with action, as giant trevallies hunted glassfish, while a potato grouper and a passing mobula devil ray made for unforgettable moments! (sorry no photo of this one).

Koh Lanta National Park – A Blue Marlin Encounter

​Day 6: ​Returning to Hin Daeng and Hin Muang, we enjoyed more encounters with their spectacular marine life. However, the real highlight of the day came during our third dive at Cathedral—as we explored its underwater caves, we were stunned to witness a rare blue marlin, a once-in-a-lifetime sighting!
Our final dive at Chimney took us through a dramatic vertical tunnel, where a pair of ghost pipefish greeted us at the exit.

Day 7: Koh Phi Phi & Shark Point – The Grand FinaleOur last full day of diving started at Bida Nok, where we explored shallow waters teeming with blacktip reef sharks, massive schools of yellow snappers, and a thriving coral reef.
For the final dive of the trip, we visited Shark Point, an absolute paradise for cephalopod lovers. We encountered bigfin squids, cuttlefish, and a breathtaking moment with a large leopard shark (zebra shark) resting on the sandy bottom.

An Unforgettable Adventure in the Andaman Sea.
From thrilling drift dives and intricate swim-throughs to mesmerizing blackwater encounters and a rare blue marlin sighting, this North to South Andaman Sea diving expedition was truly extraordinary. A huge thank you to our fantastic group of divers for making this trip an unforgettable experience!

15th December 2024 liveaboard trip report

Six days and five unforgettable nights aboard the MV Smiling Sea Hors

The Andaman Sea is home to some of the most stunning underwater landscapes, and our journey into its heart took us to the renowned Similan and Surin National Parks. With their vibrant marine ecosystems and world-class dive sites, these destinations are a true diver's paradise.
Our guests this week was an energetic mix of adventurers from Germany, France, the UK, Australia, and Luxembourg. United by a shared passion for the ocean, we ventured into two Marine National Parks in the North Andaman, renowned for their vibrant marine life and spectacular underwater landscapes. 
​
The Similan Islands, whose name fittingly means "nine" in Malay, form a cluster of breathtaking isles. Just to the north, Koh Bon and Koh Tachai serve as gateways to Surin National Park, adding even more wonder to the experience. Departing from Khao Lak, this voyage promised a tapestry of unforgettable sights above and below the surface.

Day 1 : Similan National park - Honeymoon bay, West Of Eden, Elephant head and Turtle Rock

We started our adventure with a check dive at Honeymoon Bay (Island Number 4). The coral garden and pristine sandy bottom were teeming with marine life: moray eels, lionfish, peacock groupers, and an octopus made appearances, while Camille spotted a stunning comet longfins. Divers also encountered sealface pufferfish, gobies, butterflyfish, and the graceful humpback unicornfish.

Our second dive took us to West of Eden (Island Number 7), where we marvelled at a vibrant coral garden bustling with life. Juvenile rockmover wrasse danced in the sand, and blue-spotted pufferfish peeked out from coral crevices. Angelfish, snappers, fusiliers, surgeonfish, and tilefish were abundant, making this dive truly delightful.

For our third dive, we explored the iconic Elephant Head Rock, renowned for its massive boulders and swim-throughs. Highlights included a giant trevally, a blue-and-yellow ribbon eel, and colorful nudibranchs adorning the rocks. Divers also spotted parrotfish, triggerfish, and a playful school of bluefin trevally hunting glassfish.
​
The day concluded with a mesmerizing night dive at Turtle Rock, near Donald Duck Bay. Shrimps and crabs were out in abundance: banded boxer shrimp, marble shrimp, and Durban dancing shrimp stole the show. A giant moray eel stalking a snapper added an element of drama, while a tiger cowrie and an ornate spiny lobster rounded off our enchanting night.

Day 2 : Similan islands

We began the morning at Xmas Point, where one group was delighted to discover a pair of baby harlequin shrimps munching on a sea star while another group came across a white-tip shark swimming closeby and a curious octopus. Parrotfish and titan triggerfish also came for a quick glance as we explored this dynamic dive site.

Our second dive took us to Three Trees, where we encountered a playful hawksbill turtle and observed garden eels swaying gently in the sand. The highlights of this dive included potato groupers and Moorish idols, as well as blue-spotted rays gliding elegantly through the water.
​
Next, we made our way to Koh Bon Bay, where we were greeted by a school of platax (batfish). The spectacle was enhanced by the presence of lionfish, lobsters, and peacock mantis shrimps, along with yellow fusiliers and bluefin trevally darting through the reef.
We concluded the day with a dive at Koh Bon, which featured Andaman sweetlips, tapestry shrimp, and squat shrimps. An octopus made a memorable appearance, and we were particularly thrilled to spot the vibrant halgerda tessellata nudibranch, which was truly a special treat.

Day 3: Koh Bon and Koh Tachai

Some divers began their day at Koh Bon West Ridge, where Maldivian sponge snails, schools of fusiliers, triggerfish, batfish, and anemonefish were abundant. While others explored the deeper Koh Bon Pinnacle, which was equally rich in marine life.

For the second dive, we ventured to Koh Bon North Ridge and North Reef, enjoying remarkable visibility and sunlight streaming through the water. Divers spotted banded sea snakes, barracudas, lionfish, and baby fimbriated moray eels. Shrimp, including Durban dancers and boxing shrimp, added charm to the reef.
​
Dive three took us to Koh Tachai Pinnacle, where the light and visibility were breathtaking. Schools of fusiliers and snappers swarmed around the reef, while giant potato groupers and pufferfish lingered on the plateau. A school of batfish hovered near the walls, accompanied by octopuses and stunning sea fans.
The sunset dive at Koh Tachai Pinnacle featured no current and an abundance of marine life. Mackerel, giant trevally, dogtooth tuna, and schools of fusiliers swirled around the site. Potato groupers and a small yellow boxfish provided a perfect ending to the day.

Day 4 : Surin National Park

The wind picked up as we made our way toward Surin National Park, prompting us to adjust our plans for safety. We began our adventure at Yellow Rock, located on the southern tip of South Surin Island. Although the visibility and current posed some challenges, our most determined divers were rewarded with sightings of a school of yellowtail barracuda, a massive school of yellow fusiliers, and a solitary humphead parrotfish.

Our second dive at Bungalow Rock, situated northwest of South Surin Island, offered calmer conditions and clearer waters. The underwater landscape was vibrant, featuring boulders teeming with life, including barracudas, sweetlips, shy potato groupers, and a giant moray eel that made this dive truly memorable.
​
The final two dives of the day took us to the legendary Richelieu Rock. Although the visibility wasn’t perfect, the site delivered its usual enchantment. Schools of yellowtail barracuda, pickhandle barracuda, trevally, rainbow runners, fusiliers, and snappers painted a mesmerizing underwater scene. The sight of cuttlefish laying eggs added to the excitement, while as the sun began to set, the waters came alive with activity as predators started their hunt.
After the sunset dive, we celebrated with a barbecue in the bay of the Surin Islands—a well-deserved feast for our hardworking divers.

Day 5: Richelieu Rock and return to Koh Phayam and Ranong

The trip concluded with two final dives at Richelieu Rock, which once again showcased its incredible biodiversity. Schools of barracuda mingled with fusiliers and snappers, while longnose emperors prowled near the rock. Boxfish, trumpetfish, and blue-spotted boxfish were just a few of the vibrant reef inhabitants we encountered. Porcelain crabs, peacock mantis shrimps, and Durban dancing shrimps delighted macro enthusiasts.
​
With smiles on our faces and memories of breathtaking dives, we headed back toward Ranong, making a brief stop at Koh Payam to drop off some guests. This journey was truly unforgettable.

Day 1: Koh Lanta National Park – A Stunning Introduction

We began our adventure at Koh Haa with a relaxing check dive. The tranquil waters revealed schools of fusiliers and snappers, while a lionfish glided past and a beautiful sea slug rested on the white sandy bottom—a serene start to the trip.
At Hin Daeng, the underwater world came alive. We explored the vibrant red rock, surrounded by batfish, giant trevallies, and rainbow runners. The sight of a giant moray eel and a porcelain crab nestled in a white anemone brought smiles to everyone’s faces. Our dive at Hin Muang didn’t disappoint either, with a mix of bluefin trevallies, baby lobsters, and a boxing-arm shrimp adding to the excitement.
The night dive at Hin Daeng was a true spectacle. One group spotted a slipper lobster, while others were captivated by marbled shrimps, banded coral shrimps, and giant moray eels on the hunt. The reef was bustling with life, from decorator crabs to sleepy seal pufferfish, making for an unforgettable end to the first day.

Our first dives at 8 Mile Rock were nothing short of magical. A school of African pompano shimmered in the clear water, and a lucky few spotted a tiger tail seahorse hiding among the corals. The highlight was a giant grouper cruising in open water, followed closely by a curious great barracuda.
At Stonehenge, the reef burst into color and life. From tiny scorpionfish blending into the rock to the ever-charming clownfish, every corner held a new surprise. Sighting of a blue dragon nudibranch and a playful group of saddleback clownfish rounded out a spectacular day.

Day 4: Similan National Park – Crystal Clear Paradise

The Similan Islands welcomed us with remarkable visibility and dramatic underwater topography, setting the stage for a day of incredible dives.
We kicked off with a dive at Shark Fin Reef, an underwater haven for large pelagic and reef life alike. The sight of a graceful marble ray gliding over the sandy bottom was a highlight, while a curious Whitetip reef shark circled in the distance. Along the reef, a massive giant moray eel peeked out from its crevice, and colorful reef fish filled the scene. Schools of blue-dash fusiliers, yellowtail snapper, and Moorish idols darted between the coral formations. Closer to the reef, butterflyfish, triggerfish, and the ever-playful damselfish added a kaleidoscope of color.
At Elephant Head Rock, we explored intricate swim-throughs teeming with life. Among the highlights were two ribbon eels, their vivid colors a stunning contrast to the rocky outcrops, and two imposing great barracudas patrolling the area.
Our third dive at Tree Threes was an ethereal experience. The sandy bottom was a field of garden eels, and the massive barrel sponges and giant sea fans on the boulders added a dramatic backdrop.
The day ended with a sunset dive at Koh Bon West Ridge, where some divers opted to try their hand at a blackwater dive, venturing into the open ocean to marvel at bioluminescent plankton and the mysteries of the deep.

Day 6: Surin National Park – Richelieu Rock's Majestic Wonders

Richelieu Rock never fails to amaze, and our four dives here showcased its unmatched biodiversity. The site buzzed with marine life, starting with schools of giant trevally, rainbow runners, and yellowtail barracuda darting around the pinnacle. Closer to the reef, the vibrant colors of anemonefish, including tomato anemonefish and clark's anemonefish, were a delight to spot.
Our divers were captivated by the macro life hiding among the rocks. Peacock mantis shrimps scuttled across the sandy bottom, while Durban dancing shrimps and banded coral shrimps made their homes in crevices. A tiny white-eyed moray eel peeked out playfully, while larger giant moray eels lounged around their rocky dens.
The soft corals, swaying with the currents, provided shelter for a plethora of reef fish, including yellow boxfish, parrotfish, surgeonfish, and bluestreak cleaner wrasse busy at work. We also encountered devil scorpionfish, pipefish, and a few colorful nudibranchs. The highlight? Watching a school of batfish glide gracefully through the water, adding an elegant touch to the vibrant underwater scenery.

Day 7: Similan National Park – A Grand Finale

Our final dive at Koh Bon Pinnacle delivered an unforgettable end to the trip. Huge schools of batfish and yellow fusiliers danced in the sunlight, weaving around the pinnacle’s striking sea fans. A majestic green turtle made a surprise appearance, swimming calmly past the group, to everyone’s delight.
Closer to the reef, the bustling community of reef fish showcased the vibrant ecosystem. Bannerfish, emperor angelfish, sergeant majors, and spotted sweetlips mingled among the hard and soft corals. A small school of Indian mackerel dashed through, while scorpionfish lay camouflaged on the sandy patches. The giant barracuda lurking near the sea fans reminded us of the sheer diversity of life this pinnacle supports.
The crystal-clear visibility and abundance of marine life were the perfect farewell to a week filled with unforgettable underwater adventures. We surfaced with wide smiles and hearts full of gratitude for this magical experience.
