Koh Tachai Pinnacle/The Dome
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. The top of is at 12 meters and the current can be the strongest in the area depending on the conditions. As a result, there are many large predatory fish such as blue and white trevally, bluefin tuna, barracudas, manta rays, and whale bays.
The middle layer is filled with a variety of yellowbacks, yellow dashes, blue dashes, and other fusiliers. At dawn and dusk you can see them being attacked by bluefin trevelly and a tornado of 1,000 blackfin barracuda. Manta rays and whale sharks are seen.
