Snorkelling in Andaman & Nicobar Islands: A Complete Guide to the Underwater World

The Andaman and Nicobar Islands are home to some of the clearest waters and most vibrant coral reefs in India, making them a paradise for ocean lovers and underwater explorers alike. Snorkelling in Andaman offers an experience that feels both thrilling and serene, with warm turquoise waters, visibility that often stretches 20-30 metres on calm days, and coral reefs lying just beneath the surface off islands like Havelock Island. Spread across 572 islands, most of them untouched and uninhabited, the archipelago offers thriving marine ecosystems that feel remarkably raw and unspoilt. Whether it is your first snorkelling adventure or another return to the Andamans, this guide covers the best spots, the ideal season, the marine life you can expect to encounter, and everything else you need to know before diving in.

Snorkelling on Havelock Island

Havelock Island, now officially known as Swaraj Dweep, is where most visitors begin their Andaman Islands snorkelling journey, and it rarely disappoints. The reefs here are accessible to beginners, varied enough to reward returning visitors, and home to some of the densest coral cover in the archipelago. Marine life appears within the first few minutes of water entry, and conditions across the main sites remain calm and clear for most of the October-May season.

Top Spots on Havelock Island

Elephant Beach: A 45-minute guided trek or a short boat ride from the main jetty, Elephant Beach is known for its shallow reef systems and vibrant marine life. The beach is also famous for its wide range of water sports and adventure activities, The beach is also famous for its wide range of water sports and adventure activities, including jet skiing, parasailing, sea walking, and inflatables.

Radhanagar Beach: Best known for its broad white shoreline, turquoise waters, and breathtaking sunsets that draw visitors from across the world. Often celebrated as one of the finest beaches in the region, it was once recognised as Asia’s Best Beach for its pristine beauty and untouched surroundings. The main stretch is perfect for sea views and sunsets, while the rocky northern end shelters small reef communities best explored between October and May.

Neil Island & North Bay: Going Beyond Havelock

For a quieter Andaman Nicobar snorkelling experience with far less foot traffic, Neil Island (officially known as Shaheed Dweep) and North Bay Island both reward the extra travel. The reefs here receive fewer visitors and have benefited from that restraint. Visibility is consistently good, and the fish behave more naturally as a result, making encounters feel less curated and more genuine.

Neil Island (Bharatpur Beach): This beach on Neil Island, officially known as Shaheed Dweep, is one of the best spots in the Andamans for close-up views of vibrant coral reefs. Often referred to as the 'coral capital' of the island, this beach is known for its shallow, easily accessible waters where both hard and soft corals thrive side by side.
North Bay Island: Just 20 minutes by boat from Port Blair, this is one of the most organised Andaman and Nicobar Islands snorkelling sites in South Andaman. Gear rental and guided entry are available directly on site, making it a good first stop for visitors arriving via the capital.

The Reef: Coral, Colour, & Clarity

The Andaman Sea is one of the most biodiverse marine environments in the Indian Ocean, and the reef systems here reflect that richness. Staghorn and table corals dominate the shallows, while deeper sections give way to sea fans, soft corals, and sponge formations that shift in colour as the light angle changes through the day. The reef fish density is high, species variety is impressive, and most fish show little anxiety around snorkellers, which makes for close, unhurried observation at virtually every site across the islands.

Life Beneath the Blue

Spend a morning in the water, and the encounters accumulate quickly. Snorkelling in Andaman means sharing the reef with a mix of large marine species and brilliantly coloured reef fish across every site in the archipelago.

Large Marine Species

Green Sea Turtles: Spotted at most reef sites, often resting near coral heads or drifting through the sandy gaps between reef structures. Particularly common near Elephant Beach and North Bay Island.
White-Tip Reef Sharks: Present along the outer reef edge at deeper sites. They keep their distance but are clearly visible from the surface during calm, clear-water sessions.

Manta Rays: Seasonal visitors, with sightings most reliably reported between November and April near the outer reef edges at Havelock and Neil Island.
Barracudas: Spotted in small schools near the surface, hovering above reef patches with characteristic stillness before moving on in formation.

Reef Fish: Colour at Every Turn

Beyond the large species, the reef fish here are both abundant and spectacularly varied. On any given session, dozens of species drift within arm's reach.

A vibrant cluster of orange and white clownfish swim closely together amongst the reef.

Parrotfish: Among the most vivid species on the reef. Their turquoise and pink colouring makes them easy to identify from a distance, and they are present at virtually every snorkelling site across the islands.
Clownfish: Found nestled in anemone clusters across every reef in the Andamans. Almost always close to the surface and entirely unbothered by snorkellers nearby.

Angelfish: Emperor and French angelfish are both present. Their bold vertical striped markings make identification straightforward, even in busy reef sections.
Surgeonfish: Schools drift across the reef in loose, shifting formations. Their steel-blue colouring catches the light as they move, creating a distinct visual display near the coral.

When to Go: Reading the Andaman Calendar

The Andaman Islands experience 2 distinct seasons: the dry season and the monsoon season. The dry season, which typically runs from October to May, brings calmer seas, clearer visibility, and ideal conditions for snorkelling and other water activities. In contrast, the monsoon season brings heavier surf, reduced visibility, and limited organised activity on the water.

Best Months for Snorkelling in Andaman

October to December: Post-monsoon waters are exceptionally clear, with visibility at its seasonal peak and relatively few visitors on the water. A strong period for first-timers.
January to March: This is the most consistently calm period of the year. Light currents, excellent visibility, and stable conditions make this the most reliable window for snorkelling in the Andaman and Nicobar Islands.

April to May: Visibility remains good, and water temperatures stay warm. Book accommodation early, as this period coincides with the Indian school holiday season.
June to September: The southwest monsoon brings rougher conditions and reduced underwater visibility. Snorkelling sessions may be cancelled or restricted depending on sea state during peak monsoon weeks.

What It Costs & How to Book

Before You Enter the Water

Tips for Your First Snorkelling Session

Use reef-safe sunscreen: Apply at least 30 minutes before entering the water. Standard sunscreens contain chemicals that bleach and damage coral reefs over time.
Do not touch the coral: Even brief contact causes lasting damage to reef structures. Keep your hands at your sides and stay aware of your fin position at all times.
Wear a rash guard: It protects your back and arms from the strong tropical sun without adding chemical residue to the water around you.

Kick slowly near the reef: Fast fin kicks stir up sediment and disturb the marine life nearby. A slow, steady kick gives better control and causes far less disruption.
Stay with your guide: Currents shift quickly around reef structures. A local guide knows the safe drift lines and the areas to avoid at any given tide.
Do not feed the fish: Feeding disrupts natural behaviour and can attract species that are harmful to reef health over time.

Where the Reef Stays with You

Snorkelling in the Andaman and Nicobar Islands is not simply about ticking off another water activity. It is about entering an underwater world that still feels wild, balanced, and wonderfully alive. From the shallow coral gardens of Elephant Beach and Bharatpur Beach to the quieter reef edges around North Bay, every site reveals a different side of the archipelago’s marine beauty. Add warm tropical waters, remarkable visibility, and marine life that appears within minutes of entering the sea, and it becomes clear why snorkelling in Andaman continues to draw travellers back year after year. Whether you arrive for a single reef session or spend days moving between islands, the experience lingers long after you leave the water behind.
