In the 1930's, the Thai government realised the strategic advantage of Koh Tao as a penal colony and started to relocate a number of political prisoners from camps on the west coast to a new facility built on the island.

From the island, surrounded for miles by ocean, there was little or no chance of escape.

In 1944 with a change of government, after all prisoners were freed and given an official pardon, the prison camp was closed down. As 'regular' people started to arrive, three main settlements emerged and to this day, Haad Sairee, Ban Mae Haad and Chalok Ban Kao.

Unlike neighbouring Koh Samui and Koh Phangan, Koh Tao remained untouched by tourism for many years. Then, in the late 1980's the first Samui based dive operators began running overnight live-aboard trips and were amazed by what they saw.....

....crystal clear waters boasting an awesome array of colour and coral reefs, alive with an incredible diversity of marine life.

Soon dive operators began re-locating to Koh Tao realizing they had uncovered a wealth of untouched beauty.

Today, Koh Tao remains one of S.E. Asia's most beautiful islands and has the image of a "picture-postcard" tropical escape!
