The Dome is the feature that names the Koh Tachai Pinnacle — a rounded summit at 12–14 m covered in hard corals that rises from the bottom at 30 m, subject to unpredictable currents that feed immense schools of barracuda and attract manta rays. It is one of the most demanding and thrilling dive sites in Similan National Park.
