After some of the best dive sites the Similan Islands have to offer, we head 16 km north from Similan Island #9 to Koh Bon.
This island is famous for Manta Rays. The dive site (5m to 35m depth) has a steep ridge and wall with lots of soft corals. Here you can expect to find leopard sharks, octopus and barracuda.
16 km north east of Koh Bon is Koh Tachai. One of the best dive sites in Thailand, Koh Tachai is often visited by manta rays and, if you are lucky, whale sharks. This dive site has barrel sponges and Gorgonian fan corals with giant granite boulders scattered around the dive site. Schools of barracudas and bat fish, leopard sharks, and rays are regularly seen here. An excellent dive site.
30km north east of Koh Tachai is the famous Richelieu Rock. Here is your best chance to see whale sharks.
The dive site (5m to 40m depth) is a pinnacle covered in soft and hard corals, with lots of schools of fish. Groupers linger on the bottom, Barracudas circle above, thousands of glassfish circle around the pinnacle. A superlative dive site.
