About Koh Tao

A small tropical paradise in the Gulf of Thailand

Koh Tao is the northernmost island of the Chumphon Archipelago in the Gulf of Thailand, the others being Koh Samui and Koh Phangan. Once considered the baby of the group, the island has matured and grown in popularity to become a must visit for anyone who finds themselves traversing the east coastline of Thailand. The Gulf of Thailand’s sheltered position provides year round ideal diving conditions for all levels!

Even landlubbers can find something fun to do, with hiking into the forested hills, rock climbing, kick boxing and swinging from a trapeze being just a few of the options available.

Koh Tao is also blessed with a wide selection of restaurants serving Thai and international cuisine being dotted along her beaches and roads.

The Diving


Koh Tao has become synonymous with diving.  With a thriving diving industry, the island has become one of the leading centers for dive education worldwide. What sets it apart from the rest? Koh Tao is fortunate enough to have diverse dive sites in close proximity, right off its shores in fact! These sites feature coral coated rock pinnacles, an overabundance of visually stunning coral reefs, shipwrecks and enough tropical reef fish to mesmerize even the most experienced of divers. Do not overlook the opportunity to see majestic pelagic fish such as whale sharks and spotted eagle rays. The Gulf of Thailand is also full of shipwrecks within the scope of both recreational and technical diving and our staff includes among the most experienced wreck divers in Thailand!
