Sea walk in Andaman is a one-of-a-kind underwater experience that lets you walk on the ocean floor without any prior diving training or swimming skills. Wearing a specially designed diving helmet that supplies continuous air, a sea walk in Andaman takes you 5-8 metres below the surface to hand-feed colourful fish, observe coral gardens, and experience the magic of the Andaman Sea up close. Available at North Bay Island and Havelock Island, sea walking in Andaman is perfect for non-swimmers, elderly travellers, and families with children.
If you've always wanted to explore the underwater world but found the idea of scuba gear intimidating, sea walking is the answer. This guide covers everything you need to know before you book how the experience works, where to do it, what you'll see, and how it compares to other underwater activities across the islands.

Sea Walk in Andaman - Key Facts at a Glance
How Does Sea Walking Work? (Step-by-Step Process)
Sea walking uses a remarkably simple principle: a large, open-bottomed diving helmet weighing approximately 35-40 kg (though it feels weightless underwater) sits over your head and shoulders. Compressed air is continuously pumped into the helmet from the surface, keeping water from entering and allowing you to breathe, speak, and even open your eyes without any mask or mouthpiece. Here's exactly what to expect from the moment you arrive at the activity centre:
Step 1: Registration and Briefing (15-20 minutes)
You'll complete a basic registration form and a short health questionnaire. The operator's instructor then runs a shore briefing covering the process, safety signals, and what to expect during the descent. This isn't a training session in any serious sense it takes about 15 minutes and requires no prior knowledge.
Step 2: Equipment Fitting
You're given a wetsuit or activity suit to change into, followed by the weighted belt that helps you descend and stay grounded on the ocean floor. The helmet itself is fitted once you're in the water, not on land.
Step 3: Entry into the Water
You board a small boat from the jetty and travel a short distance to the dive platform a floating pontoon or fixed structure positioned directly above the dive site. Steps and guide ropes lead down from the platform into the water. An instructor accompanies you into the water at every stage.
Step 4: Helmet Placement and Descent
Once in the shallow water around the platform, the guide lowers the helmet over your head. You'll feel the air pressure equalise instantly breathing is completely natural, exactly as it is on land. You then walk down the submerged steps, gripping the guide rope, until you reach the sea floor at 5-8 metres depth.
Step 5: The Sea Walk (20-30 Minutes)
This is the experience itself. Guides accompany you throughout, pointing out marine life, handing you fish food to attract schools of colourful reef fish, and directing you toward coral formations. You can turn your head, look around freely, and move slowly along the prepared area. An underwater photographer is optionally available throughout this phase.
Step 6: Ascent and Exit
The guide signals when it's time to return. You walk back up the steps, the helmet is removed at the surface, and you're helped back onto the platform. Total time in the water including descent and ascent is typically 30-45 minutes.
The entire experience from arrival to departure takes roughly 1.5 to 2 hours when you include the briefing, equipment changes, and boat transfers.
Sea Walk vs Scuba Diving in Andaman - Which Is Right for You?
This is the most common question travellers ask before booking an underwater experience in Andaman. The short answer: sea walking is easier and more accessible; scuba diving is deeper, more immersive, and ultimately more rewarding for those willing to take the plunge. Here's a detailed breakdown.
Comparison: Sea Walk vs Scuba vs Snorkelling
Best Places for Sea Walk in Andaman
Not every beach in the Andamans has sea walking the activity requires purpose-built underwater infrastructure and trained operators. These are the two main locations where you'll find it.
North Bay Island, Port Blair
North Bay Island is the most accessible sea walk location in the Andamans, sitting just a 20-minute ferry ride from Port Blair Harbour. It's the logical starting point for travellers who want to tick off sea walking without travelling all the way to Havelock.
The sea walk site at North Bay is purpose-built, with a dedicated underwater platform, guide rails, and a team of trained instructors. The coral here isn't as pristine as Havelock's Port Blair's proximity and higher tourist volumes have taken a toll but the experience is still vivid and enjoyable. You'll see moorish idols, puffer fish, damselfish, and plenty of reef activity.
The advantage of North Bay is pure convenience: it's frequently combined with a glass-bottom boat tour and snorkelling in a single day trip from Port Blair, making it the most time-efficient option for travellers with limited itinerary flexibility. Operators run multiple slots throughout the day from Rajiv Gandhi Water Sports Complex at Phoenix Bay Jetty.
Havelock Island (Swaraj Dweep)
Sea walking at Havelock Island is, by most accounts, the superior experience and it's worth the additional ferry journey from Port Blair if you have the time.
Havelock's sea walk sites benefit from significantly clearer water (visibility often exceeding 15 metres), healthier coral formations, and richer marine life. The underwater scenery feels more genuinely wild you're walking through an active reef rather than a well-trodden tourist platform. Fish are abundant, coral colours are vivid, and the overall sensory impact is noticeably stronger than at North Bay.
Havelock's sea walk is typically combined with other island activities snorkelling at Elephant Beach, a scuba introductory dive, or kayaking through mangrove channels. If you're planning a proper water sports day on Havelock, sea walking fits naturally into the morning before snorkelling in the afternoon.
For a full picture of all water activities Andaman has to offer beyond just sea walking Havelock Island has by far the deepest menu of options.
Is Sea Walking Safe? Rules & Guidelines
Sea walking in Andaman is considered a low-risk activity when conducted through a reputable, properly equipped operator. However, low-risk doesn't mean zero-risk. Here's what the safety picture actually looks like, and what you need to know before getting in the water.
Medical Conditions That May Disqualify You
Operators require you to declare any medical conditions before participation. The following may result in disqualification or require a doctor's clearance:
Ear Equalisation
The descent to 5-8 metres creates mild pressure on the ears similar to what you feel in a lift or during aircraft descent. The instructor will brief you on how to equalise (pinch your nose gently and blow lightly). It's simple and effective. If you feel significant pain at any point, signal your guide immediately never push through ear discomfort underwater.
Operator Standards
Always book through a registered operator whose equipment is visibly maintained and whose instructors are trained. Ask to see certification or registration documents if in doubt. Avoid unofficial operators offering sharp discounts at the jetty sea walking equipment that isn't regularly serviced is a genuine safety risk.
Key Safety Rules During the Activity:
Most operators accept children from age 10. Parents should ensure their child is comfortable in water environments and can follow basic instructions calmly. Children under 10, even if the operator permits, should be evaluated on an individual basis.
What Will You See During Sea Walk in Andaman?
The underwater view from a sea walk helmet is one of the most vivid sensory experiences many travellers have in Andaman partly because it's completely unexpected. Unlike looking through a snorkel mask (which frames your view) or a scuba mask (which can fog), the open-bottom helmet gives you a wide, unobstructed view of the reef in every direction.
Reef Fish - Up Close and Personal
The fish-feeding component of sea walking is genuinely memorable. Guides hand you pellets or bread, and within seconds you're surrounded by hundreds of reef fish sergeant majors, angelfish, parrotfish, wrasse, and damselfish pressing against your helmet in a swirling kaleidoscope of colour. These fish are habituated to the feeding routine and have no fear of humans, which makes the interaction feel startlingly intimate.
Coral Gardens
At 5-8 metres, you're at mid-reef depth deep enough to see substantial coral structures without going too far down. Branching staghorn coral, brain coral, and sea fans are commonly visible at both North Bay and Havelock sea walk sites. Coral health at Havelock is notably better, with larger formations and more intact structures.
Other Marine Life
Beyond reef fish and coral, sea walkers commonly spot: sea turtles (particularly at Havelock, where green and hawksbill turtles are regular reef visitors), moray eels tucked into coral crevices, sea urchins and starfish on the sandy floor, and occasional reef sharks passing at a distance. Sightings vary by site, season, and luck but the biodiversity of the Andaman Sea means there's almost always something worth stopping to look at.
Underwater Photography
Most operators offer underwater photography or video packages as an add-on (Rs.500-Rs.1,500 for a set of edited photos or a short video). A diver-photographer accompanies you throughout the sea walk and captures stills and footage of your experience. The quality varies by operator it's worth asking to see sample photos before committing to the package.
Best Season for Sea Walk in Andaman
Sea walking is weather-dependent in the same way as all other water activities across the islands. Here's how to time your visit.
October to May - Best Conditions
This is the prime window for sea walking at both North Bay and Havelock. Calm seas, warm water (27-29°C), and high visibility make for the most comfortable and visually rewarding experience. Within this window, November through March is peak season the weather is most reliable, the crowds are at their highest, and both locations are fully operational.
January to March specifically offers the best underwater visibility of the year, often exceeding 20 metres at Havelock. If photography is important to you and you want the sharpest, most colourful images, plan your sea walk during these months.
April to May - Late Season
Sea conditions remain generally good but can become variable toward May as pre-monsoon weather builds. Operators are still active, prices may be slightly lower, and crowds thin out after the school holiday peak in April. A solid option for travellers who want the full experience without the December-January peak-season pressure.
June to September - Monsoon (Not Recommended)
The southwest monsoon makes sea walking unsafe from approximately mid-May through September. Rough seas, strong surface currents, and poor visibility result in most operators closing their sea walk programmes entirely. Travel to Andaman during monsoon for water sports or sea walking is not advised.

| Photography Included | Optional add-on | Optional add-on | Self / optional |
- Choose Sea Walking if: You're a non-swimmer, travelling with elderly family members or young children, want a fuss-free introduction to the underwater world, or are uncomfortable with the idea of breathing through a regulator or wearing a full dive mask.
- Choose Scuba if: You want maximum freedom of movement underwater, plan to explore deeper reef structures and wreck sites, are comfortable in water, or want to work toward a PADI certification for future diving worldwide. For a full breakdown of dive sites, courses, and costs, see the upgrade to scuba diving in Andaman guide.
- Choose Snorkelling if: You're a confident swimmer, want the longest possible time in the water, and are happy observing the reef from the surface rather than walking along the bottom.
