Thailand’s diving sites have been rated as some of the world’s finest because they offer divers and nature lovers an exhilarating opportunity to observe a vibrant underwater world teeming with a tremendous diversity of colorful marine life.
The tropical waters around Thailand are particularly calm and clear and provide an ideal habitat for more than 200 species of coral and a myriad of other fascinating marine life. Thailand’s exceptional marine bio-diversity is the result of two distinct marine ecosystems — the Gulf of Thailand to the east with the islands of Samui, Tao, and Ang Thong, the largest marine national park, being the crown jewels of the region.
To the west, hundreds of idyllic islands are dotted around the Andaman, which forms part of the Indian Ocean. Of these tropical islands of the Andaman, Phuket and Phi Phi being the best known, while the Similan and Surin islands have been rated as world-class diving sites. On the side of the Gulf of Thailand, are more wonders to enjoy from the Thai seas.
While the Andaman is at its best between October and April, the best time to be in the Gulf of Thailand is between May and September. With access to one of the two locations at various times of the year, snorkeling and diving conditions are ideal all-year-round.
