Snorkelling and Diving in the Andaman Islands
There are beaches, and then there are the beaches of the Andaman Islands. But if you ask anyone who has been here, the real magic isn't on the shore — it's beneath it. Slip below the surface of these turquoise waters and you enter a world of vivid coral gardens, curious sea turtles, schools of electric-coloured reef fish, and dive sites so rich with life that even seasoned divers come back year after year.
The Andaman archipelago sits in the Bay of Bengal, far removed from the pollution and coastal pressures that have degraded much of India's coastline. The result is an underwater ecosystem that remains largely pristine — home to over 500 species of coral, hundreds of reef fish species, manta rays, reef sharks, dugongs, and a marine biodiversity that places the Andamans firmly among Asia's finest dive destinations.
Whether you've never put on a snorkel mask or you're a certified diver chasing your next wall dive, this guide covers everything you need to know about snorkelling and scuba diving in the Andaman Islands.
Why the Andamans Are India's Premier Underwater Destination
Most of India's coastline, while scenic, struggles with visibility, seasonal murkiness, and overfished reefs. The Andamans are different. The islands sit in open ocean, far from industrial runoff, and benefit from strict marine conservation regulations that have protected their coral systems for decades.
Visibility in peak season frequently reaches 20 to 30 metres. The water temperatures hover between 27°C and 30°C year-round, making wetsuits entirely optional. The reefs range from shallow, sunlit gardens perfect for snorkellers and first-time divers, to deep underwater walls, seamounts, and even a wreck or two for experienced divers seeking something more dramatic.
The three main islands for underwater exploration are Havelock (Swaraj Dweep), Neil Island (Shaheed Dweep), and Port Blair's surrounding islands — each offering a distinct character both above and below the water.
Snorkelling in the Andaman Islands
Snorkelling is perhaps the most democratic water activity the Andamans offer. No certification, no training, no experience needed — just a mask, a snorkel, a pair of fins, and a willingness to look. The shallow reefs here are so full of life that even a 20-minute float above the coral can leave you speechless.
Elephant Beach, Havelock Island
If there is one snorkelling spot in the Andamans that every visitor talks about, it's Elephant Beach. Accessible by a short boat ride or a forest trek from Beach No. 5 on Havelock Island, Elephant Beach is consistently rated the finest snorkelling destination in the entire archipelago.
The coral gardens here begin just a few metres from shore. Parrotfish, angelfish, butterflyfish, and clownfish dart through branching hard corals and waving sea fans. Sea turtles are frequently spotted gliding lazily through the shallows. The water is crystal-clear, and the reef is diverse enough that you can snorkel the same stretch twice and spot something different each time. Early mornings offer the calmest conditions and best visibility before the day-trippers arrive.
Bharatpur Beach, Neil Island
Set on the northern tip of Neil Island near the jetty, Bharatpur Beach is the most accessible snorkelling spot on the island — and one of the most rewarding. The reef here begins just offshore and is alive with hard and soft corals, schools of reef fish, and the occasional resident turtle. The calm, sheltered waters make it ideal for beginners and families with children. Snorkelling equipment can be hired directly on the beach, and local boat operators offer guided sessions that take you to the more productive parts of the reef.
Laxmanpur Beach Reef, Neil Island
Laxmanpur Beach is famous on land for its dramatic Natural Bridge coral formation — but beneath the surface, the reef that runs along this stretch is equally impressive. Colourful soft corals, moray eels, stingrays, and abundant reef fish make this a favourite spot for snorkellers who want to explore a little further from the tourist trail. The reef here is generally considered one of the healthiest in the Andamans, with good coral cover and excellent visibility during the dry season.
North Bay Island, Port Blair
For travellers spending time in Port Blair without a trip to Havelock or Neil Island, North Bay Island is the go-to snorkelling destination. A short ferry ride from Phoenix Bay Jetty, this island has shallow coral gardens teeming with colourful marine life. It's ideal for first-timers and families. Glass-bottom boat rides are also available here for those who prefer to stay dry while still marvelling at the reefs below.
Jolly Buoy Island, Mahatma Gandhi Marine National Park
Often described as the most pristine snorkelling spot near Port Blair, Jolly Buoy Island is part of the protected Mahatma Gandhi Marine National Park. Access requires a permit, and the island alternates with Red Skin Island seasonally to allow the reef to recover. The result is an untouched, vibrant coral system that rewards the effort of getting there. The waters are clear, the corals are extraordinary, and motorised water sports are banned in the area to preserve the ecosystem.
Kalipur Beach, North Andaman
For travellers venturing north of the main tourist circuit, Kalipur Beach near Diglipur offers snorkelling in waters that feel genuinely undiscovered. The black sandy beach gives way to crystal-clear sea teeming with sea turtles, giant parrotfish, octopus, sea snakes, and stingrays. This is also a nesting ground for leatherback turtles — one of the rarest sights in all of Indian ocean waters.
Scuba Diving in the Andaman Islands
Snorkelling shows you what lies just beneath the surface. Scuba diving takes you all the way in. The Andamans have dive sites for every level of experience — from shallow, beginner-friendly reef dives to advanced wall dives, drift dives, and shipwrecks that require significant skill and experience.
Diving at Havelock Island (Swaraj Dweep)
Havelock is the undisputed diving capital of the Andaman Islands, home to the greatest concentration of world-class dive sites in the archipelago. Most dive centres on the island offer PADI and SSI certified courses, fun dives for certified divers, and introductory "discover scuba" experiences for those taking their first dive.
Nemo Reef is the most popular site for beginners and first-time divers. True to its name, the reef is home to large numbers of clownfish nestled in sea anemones, along with a rich variety of corals and reef fish. The shallow depth and calm conditions make it the ideal introduction to scuba diving.
The Aquarium lives up to its name entirely. This shallow dive site is a haven of colour — angelfish, parrotfish, and butterflyfish swarm through the corals in every direction. Resident sea turtles glide through with characteristic unhurried grace. Even non-swimmers can experience this site under supervised conditions with certified guides.
Barracuda City is the spot for divers who want a little drama. A sweeping reef system with a healthy mix of hard and soft corals, this site is home to schools of barracuda that circle overhead in mesmerising formations, alongside white-tip reef sharks, manta rays, marbled rays, and large humphead parrotfish. It's also a good site for turtle sightings.
Dixon's Pinnacle is one of the most celebrated dive sites in Havelock — a collection of three massive underwater pinnacles covered in vibrant corals and buzzing with cleaning stations where fish queue patiently for a grooming session. The mild currents make it suitable for divers of all levels, and the sheer variety of life here — from tiny nudibranchs to passing Napoleon wrasses and reef sharks — makes every dive here unique.
Jackson's Bar, named after a British naval officer, is a site for experienced divers. Strong currents sweep over dramatic vertical rock formations creating swim-throughs and caverns, while large pelagic species including tunas, manta rays, eagle rays, and reef sharks patrol the blue water just beyond the reef edge.
The Wall is precisely what the name suggests — a sheer underwater cliff that drops from 10 metres all the way to 55 metres before tapering off into the channel between Havelock and Peel Island. The upper sections are encrusted with fan corals, and the wall itself hosts octopus, scorpionfish, crocodile fish, Napoleon wrasses, and large schools of snappers. The changing tides create strong currents here, making it better suited to advanced divers.
The Inchkeith Wreck is a fascinating dive for those who enjoy shipwrecks. An inter-island cargo vessel that struck a reef and sank near Duncan Island in 1955, the SS Inchkeith now lies in shallow water with its enormous propellor sitting upright at the stern. The wreck is covered in soft corals, scorpionfish, and cleaner shrimp. Visibility is often low, which only adds to the atmospheric quality of the dive.
Johnny's Gorge is a unique site — a deep gorge running through the reef that creates a dramatic underwater topography of passages, overhangs, and cathedral-like spaces filled with soft corals, giant sponges, and schools of fish moving like living curtains through the water.
Diving at Neil Island (Shaheed Dweep)
Neil Island's dive sites are less crowded than Havelock's, and the reefs are often described as being among the healthiest in the Andamans. The smaller number of visiting divers means the underwater environment feels more intimate and pristine. This is the diving destination for those who value quality over quantity.
Margherita's Mischief is one of Neil Island's standout sites — a boat dive suitable for both beginners and more experienced divers. The site features excellent coral cover, resident turtles, stingrays, and moray eels, with the chance of spotting reef sharks and large pelagic fish on a good day.
Junction is another of Neil Island's finest dive sites. This is where turtles, stingrays, and moray eels are seen with reliable frequency, and the coral structures here are particularly impressive. The site gets its name from the convergence of currents that bring nutrients to the reef, which in turn sustains the remarkable density of marine life.
Jetty Channel Marker is a favourite for beginners making their first boat dive at Neil Island. The site offers calm conditions, good coral cover, and all the photogenic reef fish that make diving in the Andamans such a rewarding visual experience.
The three beaches of Neil Island — Bharatpur, Sitapur, and Laxmanpur — also offer shore diving opportunities with immediate access to the reef system right from the beach, making Neil Island particularly well-suited to divers who want to simply walk in from shore at their own pace.
Diving around Port Blair
While Havelock and Neil Island are the main diving destinations, Port Blair's surrounding waters offer some genuinely impressive sites for those with limited time.
North Bay Island has shallow reefs suitable for introductory dives and snorkellers, making it one of the most accessible dive experiences near the capital.
South Button Island is a small island about halfway between Havelock and Port Blair that offers excellent diving with strong marine diversity. The reefs here include good hard coral cover, turtles, rays, and a variety of reef fish species.
Snorkelling vs. Scuba Diving: Which Is Right for You?
Both activities offer a window into the same extraordinary world — the question is just how deep you want to go.
Snorkelling requires no training, no certification, and minimal equipment. You float on the surface, breathe through the snorkel tube, and observe the reef below. It's ideal for families, children, non-swimmers (with a life jacket), and anyone who wants a relaxed, low-commitment introduction to the underwater world. The Andamans' shallow reefs are vivid enough to make snorkelling a genuinely spectacular experience.
Scuba diving allows you to descend into the reef, move freely through the water, and encounter marine life that exists only in deeper zones — reef sharks, manta rays, large pelagic fish, cave systems, and underwater topography that snorkellers simply can't access. For first-timers, most dive centres offer introductory "discovery" dives where a certified instructor accompanies you throughout the entire experience. No prior training is needed.
For those who want to pursue diving seriously, PADI and SSI certification courses are widely available across both Havelock and Neil Island, taking you from complete beginner to certified open water diver in 3 to 4 days.
Essential Tips Before You Go
Book with certified operators. Always choose dive centres that employ PADI or SSI certified instructors. Never dive or snorkel unsupervised unless you are an experienced, certified diver familiar with the site.
Do not touch the coral. The coral reefs of the Andamans are fragile and irreplaceable. Even brushing a coral with a fin can kill the polyps that built it. Stay neutrally buoyant, watch where your fins are, and leave nothing behind but bubbles.
Check the tides. Some sites, particularly the Natural Bridge at Neil Island and certain snorkelling spots, are best visited at low tide. Ask your resort or dive operator for advice before heading out.
Respect the marine life. Do not chase, corner, or attempt to touch any marine creature — including sea turtles. Keep a respectful distance and let the wildlife come to you.
What to wear. A rash guard or light wetsuit top protects against sunburn and the occasional jellyfish. Full wetsuits are not necessary given the warm water temperatures.
Permits. Indian nationals generally do not need special permits for the main snorkelling and diving spots, though sites within the Mahatma Gandhi Marine National Park (such as Jolly Buoy) require day entry permits. Foreign travellers should register at designated immigration checkpoints. Your resort or dive operator can guide you on current requirements.
Best Time to Go
The ideal window for snorkelling and diving in the Andamans is October to May, when the seas are calm, visibility is at its best, and conditions are consistently good across all dive sites. The sweet spot for most travellers is November to February, when the weather is pleasantly cool, the water is crystal-clear, and the island is at its most alive.
March to May is warmer but still offers excellent conditions with thinner crowds and more flexibility in bookings. The monsoon (June to September) brings rough seas and often suspends ferry services and dive operations, though experienced divers sometimes find excellent macro diving conditions during this period.
