Koh Tao (Turtle Island) - One of the Most Popular Tourist Spots in Thailand
Initially, the island was uninhabited, with only the occasional fisherman from the neighbouring islands, in searching of shelter in a storm or simply resting before continuing his journey. It will be appear from old maps and details that this island was known by the European cartographers and the sailors as "Pulo Bardia", which indicates that it was first settled by Malayo-Polynesian peoples. The old maps show a chain of three islands aligned north-south and lying off the east coast of the Malay Peninsula. The most northerly and the smallest of these islands has been marked P. Bardia, which was named until the 1900s.
Koh Tao is one of the most popular tourist spots in Thailand. The island is well known for scuba diving and snorkeling, but you can also enjoy here 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, which is located to the south of the island is becoming increasingly popular as an alternative for those wishing to escape the crowds. There are many granite boulders which attract a growing number of climbers both in the forests and on the beaches of Koh Tao. But due to a series of tourists deaths - including murder and alleged suicide - especially since 2014, some people have advised that the tourists should avoid visiting Koh Tao.
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 warmer water temperatures over the last year a great number of bull sharks have migrated to cooler waters. The island is host to over 130 species of hard corals, and over 223 species of reef fishes belonging to 53 families. As one of the world's most popular diving destinations, more attention is being focused on the negative effects of diving on coral reef health around Koh Tao.
