Thailand is a remarkable country full of history and culture, friendly natives who offer various services, beautiful national parks, a wide range of accommodation possibilities at every price level, extraordinary food, and exotic tropical fruits in the world. Hence, with over 50 dive centers located on the islands and towns in the Gulf of Thailand and the Andaman Sea, visiting some of the best dive sites in the world has never been easier. Thailand's reefs feature hundreds of both hard and soft corals. Large pelagic fish, including whale sharks, silver tip sharks, and manta rays are seen frequently. The amount and variety of tropical Indo-Pacific fish will impress even the most seasoned diver.
Diving is popular all year round at all dive sites around Thailand.
However, the best time of the year for the Andaman Sea and most other areas is between October and June when the seas are calm and flat and the traveling range of dive boats is increased dramatically.
