Koh Tao island is located approximately 70 km east of the coastline between Suratthani and Chumporn in the Gulf of Thailand and is about 21 km2 in size - so small but not too small. Koh Tao is unique in many ways and not just because it offers the best scuba diving in the Gulf of Thailand. Conveniently small, with a real international community, truly great cuisine at reasonable prices, fantastic night life, exciting activities and stunning vistas, Koh Tao really is full of surprises! The island boasts about 30 different dive sites all pretty close by, with the furthest away being Hin Bai. Check out the variety on offer with the dive sites maps and their proximity to the island. And don't forget that you just never know what surprises you may find beneath the surface around Turtle Island!
