Thailand offers spectacular scuba diving in many of its protected marine parks located on the west coast and in the Andaman Sea.

Diving in Thailand is available for all certified divers. Conditions are ideal for newer divers to enjoy the sites while more experienced divers can enjoy the various macro and pelagic life surrounding them.

Best Places to Dive in Thailand

The best scuba diving in Thailand can be divided into two areas:

The Similan Islands is a chain of 9 islands running north-south with many diverse dive sites. Each island has its own unique dive sites. On Islands number four and eight you can visit the gorgeous white sandy beaches.

If the north does not offer enough variety, there are liveaboards to the South Andaman. They visit the pinnacles of Hin Daeng and Hin Muang, (Red and Purple Rock). They are often called the Richelieu of the south. Mobula rays, manta rays and whale sharks are seen here regularly. To get to this distant area, you stop at Koh Haa. These five uninhabited islands offer a huge diversity of marine life with swim throughs, soft corals and turtles galore.

The famous Phi Phi is also in this area with the picturesque Maya Bay and the brother islands on Bida Nok and Nai of the south. Black tip reef sharks hunting during your safety stop are one of the many highlights of these dives.
