Do you want to escape the mainland on an exciting ocean adventure to discover and photograph a vast array of colorful and exotic aquatic species? Do you want to seek glimpses of whale sharks and Manta rays? Let us guide you on a unique experience through the Thai waters of the Andaman Sea...
Let’s dive in the heart of theSimilan and Surin National Parks...
Similan and Surin Islands National Park is an archipelago in the Andaman Sea in the Phang Nga province, in the south of Thailand. Originally compiled of 9 islands, the parks have expanded to 11 unique destinations.
Among the islands, Koh Tachai, and Koh Bon (a renowned Manta hot spot) are must-see destinations. These paradises on earth are rarely visited, so you can enjoy most dives undisturbed by others, making them both peaceful and especially appealing for photographers. From steep limestone walls and pinnacles to white granite rock, the variety of habitats offer a wide range of marine life species to be encountered.
Far from civilization, the best way to discover these special places is with us on the MV Smiling Seahorse. Between dives, you will be able to cruise through clear deep waters, relax on our brand-new boat, and taste Thai specialties crafted by our chefs.
We will help you plan everything you need for your trip, ensuring it will be the best you’ve ever experienced!

Here are just a few of the common critters we see on our cruises:
Cuttlefish: belonging to the octopus family, cuttlefish have large, W-shaped pupils, eight arms, and two tentacles furnished with denticulated suckers. They measure between 15 and 25 centimeters.
Octopuses: the well-known largest genus of octopuses.
Schools of fish: we will encounter them in many places, each site offering a variety of possible species.
Whale sharks: it’s a lucky day of diving when you encounter one of these behemoths! Slow moving, filter feeding sharks, they are the largest fish on the planet.
Barracudas: they often live alone when they are adults, but when they are younger, they live in schools. Barracudas are hunters and use surprise tactics in action.
Hawksbill turtle: belonging to the sea turtle family, they are critically endangered. Resembling other turtle species, they can be distinguished by their curvy sharp beak.

Seahorses 😊: our famous symbol has a unique morphology. Nourished by tiny crustaceans, some can change their color to blend in their habitat. What’s interesting about seahorses is that the males become pregnant and carry babies to term.
Mantas: easily recognizable, they are very large (some of them can reach 5.5 meters). They nourish themselves with a water filtration technique.
Ornate ghost pipefish: an unusually shaped species, they are often compared to seahorses, but they have two dorsal fins whereas seahorses have only one and have slender appendages on their bodies.
Back and white tip sharks: black tip sharks are name for the black tip coloration on their pectoral, pelvic, caudal and dorsal fins. Great White Sharks are a well-known variety of these sharks and are also one of the most dangerous sharks in the world. They are carnivores, but humans don’t seem to be a part of their diet.

What photography gear will I need?
During your cruise in the Surin and Similan islands you will have the chance to visit the most unspoiled dive sites in the area, showcasing a variety of both seascapes and marine life.
We understand that ease of travel and luggage fees can create problems in selecting the right gear to bring, especially when your goal is to take the maximum number of pictures possible!
The best way for you to travel light is to take a digital compact camera and underwater housing. It will be convenient to carry through a dive with strong currents and it takes up little space. Moreover, in order to achieve different artistic goals, they can be paired with diverse attachments and usually have built-in underwater settings. For example, you can use them with a wet wide-angle lens to capture larger animals or schools of fish, but also without the lens for close-up shots.
If you consider yourself as more of a pro, the best equipment you can carry is a mirrorless of DSLR camera, which is equipped with both a 60mm or 105mm macro lens and a wide-angle lens of 10-17mm or 10.5mm. It will be more comfortable for you to have both lenses and you will be able to adapt to your target, depending on the dive, the site and its conditions.
Don’t forget that the most important thing, whether you have a simple go-pro or a pelican case full of expensive toys, is to always consider your lighting. What will always be helpful are strobes. With strobes, your photos will come out with the highest quality, containing the entire color spectrum. Moreover, you can carry a focus light that will compensate for low-light spots and will be helpful during night dives.
If you consider yourself as a mega pro, we may recommend you to bring a wet diopter for good measure. Being able to switch between macro and super macro will be super convenient for you when you discover the tiniest (and often the most unique) creatures. We can also recommend you bring a 1.4 teleconverter to pair with your 10.5mm wide-angle fisheye lens. This great option will offer you capabilities to shoot from the smallest nudibranch to the mighty Manta ray.
One last piece of advice that we must give you is to bring reef hooks, even if they are not specific to photographers. Certain areas that are sheltered and have mild currents, but some spots can get bring stronger currents depending on your position on the site and the moon phase. Reef hooks can help secure yourself to line up your shots by attaching yourself to the reef. However, you must be careful when attaching yourself because the corals are fragile, and you do not want to damage them. Moreover, remember to tuck the hooks into your pocket when you are not using them to avoid entanglement

Wide angle tips:
1-Always be ready!
As much as you can expect to see mantas and whale sharks during your dives, you can never predict the exact moment or for how long it will last. You should always be vigilant and ready to shoot in case the magical moment arises when a manta soars out of the blue before your eyes.
2-Pre-set your camera for the lens you use before getting in:
I have often seen an eagle ray as soon as I jumped in. The difference between the perfect shot and a missed opportunity? preparation!
3 - Test out your settings as soon as you enter the water, adjust your lighting and test shoot.
My standards settings for 10.5mm are ISO 200, F 8, 1/200 but of course they always need adjustment throughout the dive.
4- Always think and try to shoot upward, this way you will get some light. The blue water on the background makes for much better pictures.

Get more close!!!!!

Macro tips:
1- Stop, breathe, think, act! Does that remind you of something?
The idea is that when you or your guide spots a little critter, always be sure to give your subject a little breathing room so you don’t scare it before getting your chance to capture it on camera. So, STOP and think of a few things before snapping the shot. Are your settings appropriate for this subject? What will the best angle be? Now you can approach slowly trying to keep your subject in the viewfinder until you are close enough to capture even the smallest detail and texture.
2- When you think you are close, get closer!
My standards settings for 60 mm macro are ISO 100, F 22, 1/160

Koh Bon and Koh Tachai:
|
Located in the north of the Similan Islands, these are some of the most widely known dive sites in the whole world. Waters here are so clear that you have a near constant good visibility.
Koh Bon offers an especially rare terrain: a 33-meter vertical wall where you can observe famous manta rays and leopard sharks. Moreover, the corals in Koh Bon are distinguished for their vibrant colors and diversity. We’ve never seen corals this lush and vivid. 25 kilometers north Koh Bon, Koh Tachai allows us to discover a spectacular submarine landscape and large schools of fish. You can even have the chance to see a Whale Shark here - the biggest fish species living on Earth! |

What equipment to take on this adventure?
The compulsory:
To surface safely, a surface marker buoy (SMB) is necessary, especially if you are separated from you diving buddies.
A dive computer will be needed to monitor your dive time and no deco time. We will be diving 4 times per day and most often deeper than 20m, so you will be at a high residual nitrogen level that your computer can help monitor for you.
Remember to bring exposure protection, especially for several days of diving. We generally recommend a full 3mm wetsuit but you should also consider your photo objectives and tolerance to temperature. For example, if you are a bit chilly and you want to focus on macro photography, at the end of the dive you will be please to have brought extra layers, a thicker wetsuit or a hood.
The strongly recommended:
The average depth of the sites we will visit is 25m, and if you do not want to cut the dive short due to low NDL, you should dive using enriched air (Nitrox) to enjoy the most dives per day at the highest energy levels. We offer this brief course on-board if you are not yet certified.
A diving torch (flashlight) is always useful as some spots are not exposed to sunlight or have hidden crevasses to explore or to participate in night dives.
To conclude, we advise you to have your own equipment that you are comfortable in and fits you well.
The optional:
During your cruise you will also enjoy time out of the water and will be able to see wonderful landscapes and wildlife, like birds (sea eagles), turtles, dolphins, whales or even hunting schools of fish from the surface. So consider bringing another camera that will stay dry and handy on board!
