On June 18, 1899 King Chulalongkorn visited Ko Tao and left as evidence his monogram on a huge boulder at Jor Por Ror bay next to Sairee Beach. This place is still worshiped today.
In the 1980s the first travelers discovered Ko Tao and their special backpacker network quickly made it widely known and a popular destination. As a consequence, bigger, faster and safer boats were used to allow easier access to Ko Tao. In the 1990s the island finally became known as a diving site.
The island is well known for scuba diving and snorkeling. Also offers some hiking, rock climbing and bouldering. The most popular place for tourists is Sairee on the West coast, which has a white sandy beach of 1.7 km interrupted only by a few huge boulders and a scattering of medium budget resorts and restaurants. Chalok Baan Khao, to the south of the island is becoming increasingly popular as an alternative for those wishing to escape the crowds. A multitude of beautiful granite boulders, which nestle both in the forests and on the beaches of Ko Tao, attract a growing number of climbers who visit each year to enjoy the adventurous aspect of their sport.
Diving conditions have improved dramatically in the past few years with the continuing education of locals by the dive community. The El Nino weather pattern of 1997 caused a warming of the waters which resulted in the loss of a great deal of the shallow corals near the island. Since then, the recovery has been swift and dramatic. And with help by island conservation groups the island environmental outlook is strong.
Chumpon Pinnacle, a dive site to the west of the island has a reputation for divers in search of both whale sharks and bull sharks. However, because of the warmer water temperatures over the last year a great amount of bull sharks have migrated to cooler waters.
With few exceptions, almost all roads on Ko Tao are dirt roads and generally are in poor shape. However, new roads are being paved at a quick rate. 95% of all traffic on the island is motorbike, with mopeds and dirt bikes being the main mode of transport. Motor bike accidents are the most common injury on the island. Poor roads, sand, reckless taxi drivers and drunkenness are all a factor.
