The Andaman Islands cover an area of just over 8,000 square kilometres, and with 500 islands, islets and rocky outcrops, they are best discovered by liveaboard diving. The larger islands are mountainous and blanketed with dense rainforest, with no less than 94 wildlife sanctuaries.

Many of the islands in the Andaman area are surrounded by fringing reefs, really only accessible by liveaboard diving. Large pelagics such as sharks are plentiful in these waters, with schools of hammerheads often patrolling the Andaman waters away from the reefs, Grey, Whitetip, Nurse and Leopard sharks are found closer inshore, and Silvertip and Oceanic Whitetips are sometimes glimpsed.

Another feature of diving the Andaman Islands are the impressive cleaning stations where giant barracuda hover silently, waiting for their teeth to be picked. Enormous Manta Rays, bumphead parrotfish and Napoleon Wrasse are also often seen, sometimes by the dozen.
