Koh Tao's Scuba Diving

Koh Tao is an island in the Gulf of Thailand in the south of Thailand. It is a part of Surat Thani Province. It means "Turtle Island" in Thai. The island received its name because green turtles lay their eggs in the sand here. Koh Tao is washed by the South China Sea.
The island provides the best diving in the Gulf of Thailand and is rightly called the pearl of Thailand.
Those who like exploring shipwrecks, a unique object awaits — the ship Sattakut that sank in 2011.
You can find sea mounts and deep water dwellers off the island. Various species of large fish and numerous small ones dwell here.
