The Similan Archipelago is a group of nine uninhabited tropic islands lying at about 80km Northwest of Phuket. Being a Marine National Park since 1982 and considered as the ultimate dive sites of Thailand, everything is made to keep them in their currently pristine condition.

Their reputation is due to their richest variety of marine life in Thai waters (together with the Hin Daeng-Hin Muang area): not less than 500 species of hard and soft corals, and an even higher amount of pelagic and coral fish with sizes that many envy to match

The Similan Archipelago is also home to the biggest fish in the world, the whale shark, which together with manta rays, leopard and whitetip sharks are regularly encountered during the peak season.

Aside from the aquatic realm, the bottom topography is just fantastic: huge granite boulders covered with coral lie together all the way from the surface to 40 meters and beyond, providing lots of exciting swimthroughs-canyons, archways and caves, some perfect spots for U/W pictures and video effects.

We will guide you through the best sites, swimthroughs, coral reefs, drop-offs and pinnacles that the Archipelago has to offer, but not the most crowded!

SURIN ARCHIPELAGO & RICHELIEU

The Archipelago is composed of Koh Bon, Koh Tachai, the Surin Islands together with Richelieu Rock.

Then Koh Tachai, further North, with its reef in the middle of the sea, up to 35 meters, covered with granite boulders, sea fans and large school of pelagic.

The Surin Islands offer a large number of dive sites with coral garden, fields of granite boulders and therefore a wide and rich amount of fish and coral species.
