Koh Samui Underwater Paradise: Scuba Diving Tour

The Gulf of Thailand, also known as the Gulf of Siam, is a shallow northwesternly inlet in southwestern South China Sea, bounded between the southwestern shores of the Indochinese Peninsula and the northern half of the Malay Peninsula. It is around 800 km (500 mi) in length and up to 560 km (350 mi) in width, and has a surface area of 320,000 km2 (120,000 sq mi). The gulf is surrounded on the north, west and southwest by the coastlines of Thailand (hence the name), on the northeast by Cambodia and the Mekong Delta region of Vietnam, and opens to the South China Sea in the southeast.

Ko Samui (or Koh Samui, also often locally shortened to Samui) is an island off the east coast of Thailand. Geographically in the Chumphon Archipelago, it is part of Surat Thani Province, though as of 2012, Ko Samui was granted municipal status and thus is now locally self-governing. Ko Samui is Thailand's second largest island after Phuket.

Koh Tao – meaning ‘Turtle Island’ – lives up to its name, being the scuba diving destination of choice in Thailand. The perfect white-sand beaches which ring the hilly 21 km² island are surrounded by the crystal-clear waters of the Gulf of Thailand. The vibrant coral reefs there are home to a wide range of exciting and colourful sea creatures, including turtles, naturally. The compact island is 55 km to the north of Koh Samui and was only really ‘discovered’ in the early 1980s, but now supports a varied selection of hotels, from budget guesthouses and beach bungalows all the way up to five-star luxury resorts. The choice of restaurants and nightlife establishments has also been constantly growing, to the point that there is now something for almost every taste. So far from civilisation while still being relatively easily reached, it is the idyllic tropical island paradise.
