Similan National Park

Gentle Giant Liveaboard | Dive Sites In details

Koh Phi Phi boasts a diverse selection of dive sites within the Phi Phi National Park, characterized by mini-walls and shallow coral gardens.

Among these sites are Hin Bida, Koh Bida Nok, Koh Bida Nai, Pilay Wall, Hin Dot, and Ao Maya, each offering its own unique attractions. The underwater wildlife is abundant and varied, featuring frequent sightings of black tip reef sharks, tigertail seahorses, ornate ghost pipefish, cornet fish, octopus, scorpion fish, blue fin trevally, barracudas, and a multitude of other fascinating species.

Shark Point and Anemone Reef are pinnacle formations that belong to a single reef system and are situated in close proximity to one another. Both locations are adorned with vibrant soft corals and anemones, creating a stunning backdrop for divers of all levels.

The diverse marine life includes everything from barracuda to seahorses, turtles, octopuses and the iconic leopard shark!

Koh Doc Mai, often referred to as the 'Flower Island,' is a small yet remarkable sheer rock formation located between Shark Point and Phuket. Despite its size, diving at this site can offer divers unforgettable experiences.

Exploring a cavernous space, encountering frogfish, ornate ghost pipefish, and even bamboo sharks – Koh Doc Mai consistently presents surprises that leave divers with awe-inspiring memories.

Koh Haa, a cluster of five islands located to the south of Phi Phi, stands out for its diverse diving opportunities. The main attraction of diving at Koh Haa is its remarkable variety. Explore the intricate network of caves on the largest island, Koh Ha Yai, where the entrance filters the water's light to create an emerald hue.

Delve into the vertical swim-through known as "the chimney." With its walls, gently sloping reefs, and extensive beds of soft corals, Koh Haa caters to divers of all preferences. Additionally, the lagoon nestled among the islands features shallow yet thriving reefs, making it an excellent choice for night dives.

Hin Daeng and Hin Muang - Although a mere five hundred meters apart, these two dive sites offer profoundly distinct underwater experiences. Hin Daeng, or "Red Rock," emerges just above the water's surface and derives its name from the vibrant red Dendronephthya Soft Corals that adorn its upper slopes and walls.

This rock formation consists of a sequence of walls interspersed with occasional shelves at different depths. These formations gradually descend to a sandy substrate floor, averaging around thirty-five meters in depth, and in certain areas, they plunge far beyond the limits of recreational diving depths.


Hin Muang lies entirely beneath the water's surface, resembling an underwater version of Uluru. Its shallower peaks are adorned with a dense array of anemones, accompanied by their protective guardian fish. In the valleys that stretch between these peaks, you'll encounter sizable moray eels, and occasionally, vigilant triggerfish on alert.

The rich diversity of everyday reef life thrives on both sites, encompassing minute invertebrates that cater to various species of moray eels. Schools of Red, Yellow, and White Snappers gracefully navigate the waters, while the opportunity often arises to observe bamboo sharks concealed within crevices and leisurely leopard sharks resting on sandy patches.

Whale shark and Manta rays can also be spotted so keep an eye on the blue...


Similan Island National Park.

The picturesque above-water landscape boasts stunningly beautiful white sandy beaches adorned with pockets of lush forests. Explore the underwater wonders at these dive sites: Boulder City, Sharkfin Reef, Anita's Reef, and Three Trees.

Beneath the surface, you'll encounter a diverse marine life, including leopard (zebra) sharks, blue-spotted stingrays, clown triggerfish, rabbitfish, scorpionfish, snappers, emperor fish, giant trevally, and angelfish. The coral gardens, underwater bommies, and rocky boulder formations offer captivating diving experiences.

One of the Similan Islands' standout features is Elephant Head Rock, towering above the water and featuring spectacular swim-throughs. Whitetip reef sharks, batfish, trevally, and barracuda often grace the outskirts of these imposing boulders. If you scrutinize the crevices and debris, you'll spot the vibrant mantis shrimp, porcelain crab, moray eels, and cleaner shrimp.

Additionally, some dive sites are characterized by massive granite boulders, such as Deep Six, Christmas Point, and North Point, where you can witness white-tip reef sharks, schools of giant trevally, and shoals of neon fusiliers.

Koh Bon stands out as the prime spot for encountering manta rays during our Similans itinerary. Moreover, you can expect to come across Napoleon wrasse, sweetlips, octopus, bluefin trevally, giant moray eels, great barracudas, fire dart gobies, spiny lobsters, and a rich variety of nudibranchs.

The dive sites encompass a range of underwater landscapes, including dramatic wall dives, gradual sloping reefs, submerged boulders, and vibrant coral gardens.

Diving along the West Ridge offers an exhilarating drift experience, affording breathtaking views of the underwater world, while the North Reef provides a more leisurely encounter as you explore a pristine hard coral garden.

Koh Tachai dive map

Koh Tachai is renowned for its iconic pinnacle dive site, often referred to as Twin Peaks, and offers a more tranquil reef diving experience at the North Reef and South Reef. Common sightings include turtles, barracuda, pipefish, and a colorful array of nudibranchs.

Moreover, there's an exciting opportunity to encounter larger species in this region, such as manta rays and whale sharks, particularly between late January and April.

Richelieu rock Dive Map

Richelieu Rock, this limestone pinnacle derives its name from Andreas Richelieu, a former Danish Naval Officer who held the distinction of becoming the only foreign-born commander-in-chief of the Royal Thai Navy, appointed by King Chulalongkorn. Due to his profound influence and importance, the rocky outcrop was eventually named in his honor.

At low tide, this horseshoe-shaped formation only slightly breaks the surface, sloping sharply down to a sandy bottom at depths ranging from 18 to 35 meters (60-120 feet). Despite its relatively small and isolated size, this site boasts remarkable diversity.

The marine life here is exceptionally rich and includes a plethora of fascinating creatures, such as pharaoh cuttlefish, large octopuses, all five varieties of anemone fish found in the Andaman Sea, various species of moray eels, ornate ghost pipefish, smashing mantis shrimps, harlequin shrimps, tigertail seahorses, Spanish mackerel, frogfish, numerous schooling snappers, and the occasional thrilling sightings of manta rays and whale sharks.
