Andaman Islands Dive Sites

Join a liveaboard cruise to the remote and relatively unexplored Andaman Islands where the dive sites offer great variety and visibility to all levels of guests.

Andaman Islands

The Andaman Islands dive sites have a diverse topography which includes lava tubes, ash beds and volcanic substrate. There are walls, wrecks, fringing reefs and coral gardens for divers to explore. Visibility is usually good in the turquoise waters and currents are mild.

The Andaman Islands dive sites contain over 750 species of fish, sharks, rays and turtles, many are endemic to the area. 

Some of the more accessible diving is around the Havelock, Neil, Long and South Andaman islands. If you join the liveaboard cruises they also include the remote and fascinating areas of Barren Island and Button island. The first still has an active volcano producing interesting dive sites with black sand.

In general, the dive sites are relatively easy and open to all levels of divers, with a few exceptions where some experience is required.
