An easy dive site with many big rocks. In between, there are always coral blocks. This is a long dive site that is good for a drift dive.

The Dome is a hidden reef point located about 500m south of Tachai Island. A large dome-shaped bedrock shaped like an upturned plate is dotted around a large granite boulder.

As a result, there are many large predatory fish such as blue and white trevally, bluefin tuna, barracudas, manta rays, and whale bays.

Not for beginners! Koh Bon Pinnacle starts at 22m and ends at 45m or deeper. Beautiful vegetation with lots of yellow soft corals are here. There are no descent ropes available. Doing a negative entry is an advantage!

This point is located northeast of the 9th island in the Similan Islands. It is named after the three large trees that are used to mark the entry, from a shallow depth of about 5 meters to a reef slope of about 18 meters, beyond which there is a pure white sandy area dotted with isolated roots. Offshore, there are beautiful rocky areas with schools of soft corals, where you can see large fish. Because the tide splits on the island, the tide is clear and you can enjoy drift dives when the tide is strong.
