Where to find the best snorkeling around the Andaman Islands

The Andaman Islands sit about 1,200 kilometres east of mainland India in the Bay of Bengal, and their remoteness is exactly what keeps the reefs alive. Warm water holds 27 to 30°C year round, visibility often reaches 15 to 25 metres, and the islands' protected status keeps heavy industry and mass tourism at bay. For travellers leaving Sydney or Melbourne in the southern winter, the timing works almost perfectly: an Australian winter is an Andaman summer, so a chilly June trades for 30°C reef water.

Australian travellers tend to plan Indian beach trips around the southern calendar, and the Andamans fit neatly into a two-week itinerary that pairs well with Goa or Kerala. Flights from Perth via Singapore or Kuala Lumpur, or connections through Chennai and Bangalore, put Port Blair within a day's travel. Once on the islands, a small fleet of ferries and speedboats links the main snorkel hubs, and many operators expect visitors to bring reef-safe sunscreen under the tighter marine park rules now enforced across Indian waters.

Reefs, wrecks and the magic of calm bay water

The appeal sits in three layers: shallow fringing reefs, deeper patch reefs, and a few light shipwrecks that have become artificial havens for marine life in just decades. Soft corals sway over staghorn thickets, parrotfish graze in clouds, and lucky divers spot napoleon wrasse, titan triggerfish, and the occasional hawksbill turtle. Because most sites sit inside a marine national park or in zones managed by the Forest Department, anchoring and fin damage are controlled, keeping the underwater gardens unusually intact compared with busier Asian reefs.

Water clarity changes with the monsoon. From November to mid-May the sea stays flat and visibility peaks, while the southwest monsoon from June to September stirs up sediment and closes many boat routes. Australian surfers who chase calm tropical water know the feeling of hunting the right tide; here it matters even more because the best shallow gardens sit in narrow bays that glow best around high tide on a sunny afternoon.

Havelock Island: elephant beach and the shallows nearby

Swaraj Dweep, still called Havelock Island by most operators, remains the busiest snorkel base in the chain. Elephant Beach on the northern coast is the classic first stop: a 20-minute ride through banana plantations, a half-kilometre walk over forest path, or a short boat from the jetty, and you're standing in 1 to 3 metres of water over coral bombs. Turtles feed near the sandbar, sergeant major damsels dart around brain corals, and the reef slope drops just enough to satisfy beginners craving deeper water.

Quieter patches of staghorn sit between granite boulders off the western edge of Radhanagar, widely listed as Beach No. 7. Half-day boat trips from the village combine two or three sites with a thali lunch on board, a format familiar to anyone used to Great Barrier Reef day cruises out of Cairns. Many travellers extend their stay with kayaking through the mangroves of the Andaman Islands, which uses the same calm water and departs from the same jetty.

Neil Island: Bharatpur and Buddha Nallah

Shaheed Dweep, still called Neil Island, is smaller and slower than Havelock, and that matters underwater. Bharatpur's horseshoe bay has a wide reef plateau where even hesitant swimmers in float vests can watch anthias and chromis swarm above lettuce coral. The water is so shallow in places that the surface feels like a glass floor, especially on a calm morning before the boat traffic picks up.

On the island's other side, Buddha Nallah is a small natural pool reached by a bumpy scooter ride and a short walk. It looks more like a tide pool than a reef yet carries surprising life: juvenile clownfish, peacock mantis shrimp, and bright blue damselfish sheltering under bommies. Across Neil, the laid-back café culture of Fremantle or Byron Bay has crept in, with rooftop espresso bars serving Australian-style flat whites alongside masala chai.

North Bay and the underwater trail near Ross Island

A half-day boat ride from Port Blair, North Bay is one of the few Andaman sites that mixes a living reef with a sunk cargo vessel and a glass-bottom boat for non-swimmers. The "underwater trail" — submerged plaques explaining each reef zone — was set up by the local administration to ease pressure on fragile corals, and works well for families. Lionfish patrol the wreck while morays lurk in its shadow, making it the kind of site where a mask and snorkel do the job without scuba certification.

Because North Bay sits close to Ross Island, operators often string the two together and pair it with a quiet afternoon around Netaji Subhas Chandra Bose Island. Travellers wanting a softer pace after a morning of fin work often drift towards a sunset cruise in Goa once they've flown back west, since the same itinerary usually loops through Mumbai or Bengaluru on the way home.

Practical tips for travellers flying in from Australia

Most Australian visitors find a Port Blair package simpler than piecing it together on the ground, especially as domestic Indian flights from Chennai, Kolkata or Bengaluru add up fast. Carry Australian dollars in cash and a travel card linked to your bank back home; ATMs in Port Blair can run dry and smaller ferries ask for Indian rupees only. Foreign nationals need a permit on arrival, and biosecurity rules ban honey, seeds and untreated wood products, so leave the muesli bars at home.

Sunscreen rules have tightened, and oxybenzone-free reef-safe formulas are now expected at most Andaman dive shops. Australian travel insurance policies typically list snorkelling in protected waters as standard, but a quick check of the Product Disclosure Statement avoids surprises. With those boxes ticked, a ten-day Andaman loop from Sydney or Brisbane slots neatly into a longer South Asia trip without burning through all the annual leave in one go.
