About the Dome or Plateau Dive Site

The Dome or Plateau dive site is the furthest dive site from the Similan National Park, offering unique experiences and challenges. This site is known for its unpredictable and often strong currents and greater depths, making it a favorite among large fish and adventurous divers.

Huge schools of barracuda, giant trevally, tuna, and numerous smaller fish surround the area. The dive site is in open water, about 200 meters south of the island. Its topography ranges from 12 to 14 meters deep, with the option to dive down to 30 meters. During the dive, you’ll navigate through massive granite rocks and coral gardens.

What makes this dive site a favorite for many is the occasional sightings of pelagic like manta rays and whale sharks. Additionally, guitarfish, turtles, and leopard sharks like this area. However, the fantastic sights come with the challenge of often strong currents and greater depth. Therefore, this site is exclusively for advanced divers.

Koh-Tachai Reef Dive Site

Located on the side of the island, the reef extends from 0 to 30 meters in depth.  Sandy, sloping reef with hard coral reefs and rocks. Various species of stingrays are frequently encountered, and you might even spot a turtle or a leopard shark. It’s an excellent alternative for unfavorable weather conditions and for less experienced divers.
