Koh Tachai is a very small island known for diving at Twin Peaks or the Plateau.

Koh Tachai Island is a small uninhabited island roughly halfway between the Similans and Surin islands. At 165 kilometers north of Phuket and 65 kilometers northwest of Khao Lak most boat tours that come here are live aboard tours travelling from and to the Surin Islands and Similans. It is however possible to reach this area with a two hour speedboat from Khao Lak. Morning tends to be the most crowded time to dive here but doing a sunset dive doesn't mean all the action is gone.

The main features of diving here are its submerged pinnacles, large boulders and excellent wildlife. The top of the reef is build with excellent specimens of hard coral while deeper parts are known to have many boulders, sea mounts and sea fans. Most divers start at its southern more popular and deeper site while the northern side features a huge abandoned fish cage. As with other island in the area this region is common to spot white tip reef sharks, nurse sharks, manta rays and the king of all marine animals, the whale shark. Other more common species such as large schools of barracuda, Napoleon wrasses, yellow-backed fusiliers and banner fish can be found in huge numbers.
