The Andaman Islands are, without much argument, India's best place to dive. Warm water, healthy reefs, dramatic underwater topography, and a cluster of well-established dive schools make it equally suited to complete beginners taking their first breath underwater and certified divers chasing deeper sites. This guide covers where to dive, how to get certified, and what it actually costs. For trip logistics beyond diving, see our complete Andaman travel guide.
Why Dive the Andamans
Visibility regularly runs from 15 to 30 metres in good conditions, water temperatures sit comfortably in the high twenties year-round, and the reefs support an unusually broad range of marine life — reef sharks, rays, turtles, napoleon wrasse, schooling barracuda, and vast quantities of smaller reef fish. Crucially, conditions at most beginner sites are calm and shallow, which makes this a genuinely good place to learn rather than just a good place to dive.
The islands also sit far from industrial development, so the reefs are in better shape than most accessible dive regions in South Asia.
Where to Dive
Havelock Island (Swaraj Dweep)
Havelock is the diving capital and where most people base themselves. It has the highest concentration of dive schools, the widest range of sites, and the infrastructure to support multi-day courses.
Nemo Reef and Turtle Bay are the standard beginner sites — shallow, sheltered, and rich with reef fish. The Wall drops from around 15 to 55 metres and is a favourite for certified divers, with soft corals, gorgonian fans, and pelagic sightings. Dixon's Pinnacle is a series of submerged pinnacles known for schooling fish and larger visitors — an advanced site with current. Johnny's Gorge is regularly cited as the Andamans' best dive, a deep site with sharks, rays, and dense fish life. Aquarium and Lighthouse are versatile sites suitable across experience levels, with Lighthouse also running night dives.
Neil Island (Shaheed Dweep)
Neil is quieter, with fewer schools and a more relaxed pace. Sites like Margharita's Mischief and Bus Stop offer good macro life and gentler conditions. It suits divers who want a less busy scene, though the range of sites is narrower than Havelock's.
Port Blair and North Bay
Port Blair is mostly a transit point, but North Bay offers accessible shallow reefs and is where many day-trippers do their discover-scuba sessions. It's convenient rather than exceptional — if diving is your priority, get to Havelock.
Diving as a Complete Beginner
You do not need to know how to swim particularly well, and you do not need prior experience. A Discover Scuba Dive (often called a try dive) takes half a day: a briefing, basic skills in shallow water, then a guided dive to around 12 metres with an instructor beside you throughout. It's the standard entry point and requires no certification.
This is the right choice if you want to see what diving is like without committing several days to a course.
Getting Certified
If you want to dive independently and keep diving elsewhere, a full certification is worth the time.
Open Water Diver is the entry-level qualification — typically three to four days, covering theory, confined-water skills, and four open-water dives. It certifies you to dive to 18 metres anywhere in the world. Havelock is a genuinely good place to do this: calm conditions, warm water, and experienced instructors.
Advanced Open Water takes another two days and extends your depth limit to 30 metres, opening up sites like Johnny's Gorge and Dixon's Pinnacle. Most schools offer both PADI and SSI pathways; the certifications are equivalently recognised, so choose the school over the acronym.
Build buffer days into your itinerary. Courses run to a schedule and weather occasionally interferes — leaving yourself no slack means risking an incomplete certification.
Best Time to Dive
The dive season runs October to May, closely tracking the general tourist season. December to April offers the best visibility and calmest seas, and is the window most serious divers target. March and April are often cited as the peak for water clarity.
June to September is monsoon. Most operators close, seas are rough, and ferries are unreliable. Diving is effectively off the table.
Costs and Practicalities
Diving in the Andamans is reasonably priced by international standards but represents a meaningful add-on to your trip budget — a try dive is a modest expense, while a full Open Water certification is a significant one. Prices vary between schools, and the cheapest option is rarely the right one.
Choose your school on instructor-to-student ratio, equipment condition, and safety record rather than price. Small group sizes matter enormously as a beginner. Reputable schools will happily discuss their ratios and show you their gear.
Practical notes: leave at least 18 to 24 hours between your last dive and any flight, which means not scheduling diving for your final day. Bring any personal medication and declare relevant medical conditions honestly on the pre-dive questionnaire — asthma, heart conditions, and recent surgery all matter. Reef-safe sunscreen is worth packing. Cash is useful, as card facilities at dive schools can be unreliable.
Who Should Try It
Diving in the Andamans suits complete beginners curious to try it, travelers wanting to certify somewhere warm and calm, and experienced divers looking for healthy reefs without leaving India. It's less suited to those on a tight two-or-three-day itinerary, where ferry time eats most of the trip.
