Reefs

Beneath the surface: diving the Andamans

By the Andaman Travel Tree editors·10 min read

For many travellers the Andamans are a beach destination that happens to have reefs. Spend one morning underwater and the order reverses. The water here is famously clear, the coral still largely healthy, and the marine life ranges from clouds of glassfish to the occasional reef shark gliding past at the edge of visibility.

You do not need a licence to start. Most first-timers begin with a guided "discovery" dive in shallow water, and many never look back. This guide explains where to go, what you'll see, and the small things that keep these reefs worth visiting at all.

The best dive is the one the reef survives. Look closely, touch nothing.

Snorkelling vs diving

If you only ever put your face in the water with a mask and snorkel, you'll still see plenty — many Andaman reefs begin in waist-deep water just off the sand. Diving simply opens the next room: the drop-offs, the bigger fish and the sense of weightlessness that keeps people coming back. Both are easy to arrange once you're on the islands.

Where to go

For beginners

The sheltered house reefs around Havelock are the gentlest introduction — calm, shallow and well-suited to a first guided dive. Nearby sites offer easy reef dives with good odds of turtles and reef fish in fine condition.

For certified divers

Further out, dramatic rock pinnacles and deeper sites bring schooling fish, larger pelagics and the kind of visibility that makes photographers very happy. Conditions vary with the season and the tide, so listen to your dive centre over any guidebook, including this one.

What you'll see

Diving without doing harm

Reefs are far more fragile than they look, and a single careless fin-kick can undo decades of growth. A few habits make all the difference:

The quiet reward

There's a particular stillness to hanging weightless over a reef while the islands go about their morning above you. Treat it gently, and that stillness will be there for the next person who slips beneath the surface.
