Top 10 Dive Sites in India
India's diving spans two distinct environments: the tropical waters of the Andaman and Nicobar Islands in the Bay of Bengal, where conditions rival the best of Southeast Asia, and the western coast fronting the Arabian Sea, where seasonal monsoons define the diving calendar with rigid clarity. The Andaman Islands in particular host some of the most biodiverse coral reef systems in the Indo-Pacific, with visibility regularly exceeding 20 metres and water temperatures of 27–29°C from October through May. Lakshadweep, the union territory of atolls 200–400 km off the Kerala coast, offers pristine atoll diving with a strict visitor permit system that has kept diver numbers low and marine life abundance correspondingly high. Netrani Island off the Karnataka coast is accessible in the brief window when monsoon conditions subside and visibility clears.
1. Havelock Island, Andaman Islands
Havelock — officially renamed Swaraj Dweep — is the hub of Andaman diving, a compact island with a good range of accommodation and several established dive centres. The sites immediately offshore include Lighthouse, a reef wall dropping from 8 metres to 30 metres with regular encounters of large Napoleon wrasse and white-tip reef sharks. The Aquarium is a shallower site named for the density and variety of its reef fish — ideal for Open Water training dives. Water temperature: 27–29°C. Best season: November through April, before the southwest monsoon shuts down the dive operations.
2. Andaman Islands Outer Reefs
Beyond Havelock, the outer atolls and submerged banks of the Andaman archipelago are accessible by liveaboard from Port Blair. North Button Island and the reefs around Cinque Island offer undisturbed coral gardens and consistently excellent visibility. Hammerhead sharks have been recorded at certain outer banks during winter months. Barracuda, dogtooth tuna, and manta rays cruise the outer walls. The remoteness of these sites means that most of the marine life is unfamiliar with divers, producing encounters of unusual quality. Liveaboards run 7–10 night itineraries from Port Blair between October and May.
3. Neil Island, Andaman Islands
Neil Island (Shaheed Dweep), smaller and quieter than Havelock, has a resident dive community that has mapped the local sites in detail. Margherita's Mischief is a wall dive named for a regular visitor — a large female Napoleon wrasse that solicits attention from divers at the cleaning station on the wall. The K-Rock site features a series of granite boulders covered in hard corals in relatively shallow water, photogenic in good light. The fish populations around Neil are notably bold due to the island's laid-back approach to underwater interaction. Open Water divers manage most sites comfortably within 18 metres.
4. Lakshadweep Islands
The 36 islands and atolls of the Lakshadweep territory — the name means 'one hundred thousand islands' in Malayalam — are protected by a permit system that limits visitor numbers. Agatti, Bangaram, and Kadmat are the islands with approved dive operations, and the atoll diving here is world-class: clear lagoons giving way to outer reef walls that drop into deep water, with large populations of reef fish that see relatively few divers each year. Spinner dolphins visit the lagoons regularly, and hawksbill turtles are abundant on the outer reefs. Water temperature: 27–30°C. Season: November to May only.
5. Netrani Island, Karnataka
Also called Pigeon Island, Netrani sits in the Arabian Sea off Murdeshwar and is accessible in the brief window from October to May when the northeast monsoon holds and visibility improves to 10–20 metres. The island is surrounded by a wall dive that begins at the surface and drops to recreational limits. Large schools of snappers and fusiliers fill the water column, and whale sharks have been recorded here in the winter months during plankton blooms. The underwater topography is dramatic — boulders the size of houses sit on the sand floor, and the overhangs and caverns harbour sleeping nurse sharks. Access by boat from Murdeshwar or Kundapur.
6. Cinque Island, Andamans
The twin islands of North and South Cinque, accessible from Havelock or Port Blair, are surrounded by some of the healthiest hard coral in the Andamans. The reefs here were less affected by the bleaching events that damaged portions of the main island reefs, and the coral table formations, some reaching 2 metres across, are among the finest examples of intact reef structure in India. Depths across the productive zone range from 5 to 25 metres. The islands are uninhabited and strictly controlled; only licensed dive boats may approach. Best dive months: November to March for optimal visibility and calm seas.
7. Barren Island, Andamans
The only active volcano in South Asia, Barren Island produces a dramatic underwater landscape on its accessible northern face. The lava flows that reach the sea create rocky formations covered in encrusting corals and sponges, with nudibranchs and moray eels throughout. Hammerhead sharks have been reliably sighted at 20–30 metres on the wall during the post-monsoon season, and the combination of geological interest and pelagic encounters makes this one of the most unusual dives in India. The island is technically within the restricted tribal territory zone, so advance permits via a licensed Andaman operator are essential. Best season: November to January.
8. Mahatma Gandhi Marine National Park, Wandoor
The marine national park at Wandoor, 30 km south of Port Blair, protects a substantial area of coral reef and mangrove coast. The diving within the park boundaries is managed carefully, with a restricted number of boats permitted per day. The sites in the park are at their best in the post-monsoon period from October through December, when the water has had time to clear after the seasonal turbidity. Coral cover in the deeper sections of the park has recovered well from the 2004 tsunami, and sea turtle sightings are frequent. Depths across the main dive sites: 6–20 metres. Open Water suitable.
9. Gaveshani Bank, Arabian Sea
An offshore seamount about 90 km from the Maharashtra coast, Gaveshani Bank is a deep-sea expedition site visited by a small number of technical and experienced recreational divers. The top of the seamount reaches around 25 metres, and the combination of upwelling nutrients and the hard-substrate provides conditions for a dense marine community in an otherwise open-ocean setting. Whale sharks, thresher sharks, and mola mola have been recorded here. Access is challenging — a dedicated overnight charter from Goa or Mumbai is required — and the site is exposed to swell. Not a site for beginners or casual divers.
10. Kadmat Island, Lakshadweep
Within the Lakshadweep group, Kadmat is perhaps the most rewarding for divers seeking combination of atoll lagoon and outer-reef diving in a single visit. The lagoon inside the reef is sheltered, shallow, and excellent for training and relaxed reef dives at 5–12 metres. The outer reef drop-off begins at the edge of the lagoon and descends into deep water with gorgonian fans beginning at 20 metres and schools of barracuda hovering at the lip. The permit system limits visitor numbers per island per season, which means quieter boats and less disturbed marine life. Water temperature: 28–30°C.
Planning your India dive trip
The Andaman Islands season runs from October to May; the islands are largely inaccessible during the southwest monsoon from June to September. Lakshadweep requires a separate permit — obtained through licensed operators or tour agents — and the same seasonal window applies. The Karnataka and Kerala coast (Netrani, Goa) dives best November to April. Book Andaman liveaboards well in advance for the peak December to March window, when availability is limited. Most dive operators in India are PADI affiliated. Open the map to find dive centres and site locations across India's coastlines.
