The Similan Islands are considered one of the most spectacular areas for scuba diving in Thailand and one of the top ten dive sites in the world.
This group of islands lie approximately 100 kilometers, northwest of Phuket in the Andaman Sea.
The area is a marine nature park featuring some most beautiful beaches and marine life in Thailand, initially made up of a chain of nine granite islands, surrounded by clear tropical waters, breathtaking coral reefs and beautiful white beaches.
In 1982, the area was declared a marine national park, and so named Mu Koh Similan National Marine Park.
Today this group of small islands has become one of the leading attractions for visitors to southern Thailand and a favorite destination not only for scuba divers, but for yachts and tour boats as well.
In 1998 the park boundary was extended to cover two more islands, Koh Tachai and Koh Bon, these two islands are located further to the north of the other nine islands.
The Mu Ko Similan National Park authority maintains a residential center for Park Rangers and support staff on two of the islands, those being Ko Similan which is the largest Island and Ko Miang, which lies mid-way through the chain of islands.
While the Islands are an ideal destination for scuba divers; no holiday to Thailand is complete without a few days spent at the Similans.
The tropical beauty of these unspoiled islands will fascinate non divers as well, with the fine white sandy beaches and the unusual granite formations that are as spectacular as the waters that surround them.
