Johnny's Gorge — Deep-Water Sharks & Big Animals at Havelock Island (Swaraj Dweep)
Johnny's Gorge is a spectacular dive site suitable for experienced divers, situated 19 kilometres east of Havelock Island (officially Swaraj Dweep). This is a site that rewards those who venture beyond the shallows — a remote oceanic reef rising from a sandy plain, where big animals congregate and every dive feels like an encounter with a wilder version of the underwater world.
Named after Johnny, the local divemaster who first explored and charted this reef, the site has since become a benchmark dive for any advanced or deep diver visiting the Andamans. The reef's isolation means it sees far fewer divers than closer sites, and the marine life here has a boldness to match. White-tip reef sharks cruise the sandy margins unhurried, giant groupers hold their ground beneath overhangs, and visiting manta rays occasionally sweep in from the open water like slow-moving wings.
Overview of Johnny's Gorge (Quick Facts)
About Johnny's Gorge Dive Site
Johnny's Gorge is a circular reef structure lying between 22 and 35 metres beneath the surface, classified as an advanced and deep dive. The reef is essentially a mushroom-shaped rocky platform that rises from a flat, sandy seafloor. The exposed rock provides a sustainable base for corals to colonise, which in turn attract the fish that attract the sharks that give this site its legendary reputation.
Johnny's Gorge is located approximately 19 kilometres to the east of Havelock Island, making the boat ride roughly 45 to 60 minutes each way. This remoteness, combined with the depth, means Johnny's Gorge is reserved exclusively for certified Advanced Open Water divers (or equivalent with at least 30 logged dives). A minimum of two dives per visit is standard, and the site is only accessible during morning windows aligned with slack tidal conditions.
Topography
Johnny's Gorge is a freestanding circular reef — a low-lying plateau of rocky outcrops that emerges from a flat, open sandy seafloor with no surrounding reef structure in any direction for hundreds of metres. It functions as an underwater island: isolated, self-contained, and irresistible to marine life seeking shelter and food on an otherwise barren seabed. The rocky outcrops are encrusted with gorgonian sea fans, multicoloured soft corals, and whip corals in vivid hues of orange, violet, and yellow that surround the reef on all sides. Crevices and overhangs formed between the boulders provide perfect refuge for moray eels, octopuses, and resting nurse sharks, while the flat sandy margin around the reef serves as a natural resting and patrol zone for stingrays and white-tip reef sharks.
Best Time to Dive
October to April is the undisputed best window for Johnny's Gorge, with dive slots from 5:10am to 1:30pm. Seas are calm, underwater visibility is at its clearest (often 20–25 metres), water temperatures are a comfortable 25–30°C, and encounters with white-tip reef sharks, turtles, and pelagic fish are at their most reliable. Shark and ray sightings peak during this period.
Marine Life at Johnny's Gorge
The marine life at Johnny's Gorge is exceptional, even by Andaman standards. The reef's isolation and depth attract both reef-dwelling residents and open-ocean pelagic visitors. White-tip reef sharks are the signature sighting; they're seen on virtually every dive, either resting motionless on the sandy bottom or cruising around the reef's perimeter.
Schools of barracuda hang in formation mid-water, while giant trevally and yellowfin tuna make fast passes through the blue water. The resident Napoleon (humphead) wrasse are famously untimid by divers, allowing genuinely close encounters with these enormous, intelligent fish. On the reef itself, giant moray eels peer out from crevices, octopuses press flat against rock faces, and lionfish hover in slow motion beneath overhangs.
The sandy bottom around the reef is equally productive. Large stingrays and blue-spotted rays rest half-buried in the sand, and the occasional eagle ray sails overhead. On exceptional days, visiting manta rays and dolphins have been documented — these sightings cannot be promised, but they're the reason every diver surfaces from Johnny's Gorge slightly amazed.

FAQs
No. Johnny's Gorge is strictly for certified Advanced Open Water divers or equivalent. The depth exceeds 25 metres, and currents can be strong; both factors make it unsuitable and unsafe for beginners, Open Water divers, or non-swimmers. You can also complete your Advanced Open Water certification at Havelock before attempting Johnny's Gorge.
The reef base sits at approximately 25-35 metres (82-115 feet). Divers typically spend the bulk of their bottom time between 25-30 metres before ascending to shallower depths for the safety stop at 5 metres. Total dive time varies by operator and conditions, but expect around 40-50 minutes per dive including the safety stop.
Dolphins are an occasional rather than regular sighting at Johnny's Gorge. When they do appear, encounters tend to happen during the boat ride to or from the site rather than during the dive itself. Your best chance of a dolphin encounter is during the early morning passage to the reef.
Yes, it is highly recommended. Johnny's Gorge offers outstanding photography opportunities, particularly for wide-angle shots of sharks, rays, and large schooling fish. Ensure your camera housing is rated for depths beyond 30 metres. Many operators offer underwater camera rentals if you do not own one.
Certified divers (Advanced Open Water or above) pay INR 8,000 + 18% GST per person, which covers the mandatory two dives per visit.
Your dives include scuba tanks, weight belt, regulator, submersible pressure gauge, buoyancy compensator, wetsuit, mask, fins, and booties. Bring your own swimwear to wear under the wetsuit, a small towel, and reef-safe sunscreen. An underwater camera (housing rated beyond 30m), surface marker buoy, rash guard, and dive computer are optional extras worth carrying if you have them.
