Pilot Reef — Leopard Sharks & the Bannerfish Wall at Havelock Island (Swaraj Dweep)
Pilot Reef rises from the surrounding sandy bottom like a fortress, a large, complex rock formation covered in hard and soft corals. The reef stands tall above the 18–25 metre sandy base and climbs to its shallowest sections at 8 metres. It's the closest complex dive site to Govind Nagar (Beach No. 3), approximately 10 minutes by speedboat, and one of the most rewarding for divers who move slowly and look carefully.
The phantom bannerfish wall, the first landmark of every Pilot Reef dive, appears at 8 metres — a dense school hovering in a fixed position just two fin-kicks from the mooring line, unlike anything at any other Havelock dive site. And on the sandy base below, leopard sharks rest on virtually every dive: not a lucky sighting here, but the expected experience of this site's most famous section.
Overview of Pilot Reef (Quick Facts)
About Pilot Reef Dive Site
Pilot Reef is the most reliable leopard shark site accessible from Havelock. Leopard sharks rest on the white sandy base at 18–25 metres on virtually every dive, their spotted and striped patterns clearly visible from above as you approach the sandy sections from the reef edge. They're docile, unhurried animals that are accustomed to divers and allow close approach, resting motionless on the sand as divers hover above and beside them. Marble rays lie nearby, partially buried in the same sandy sections, their own camouflage patterns making them only slightly easier to spot than the leopard sharks.
Topography
Pilot Reef rises from the seabed like a fortress of coral-covered rock. The main reef structure is a large, complex patch reef, a raised rocky formation covered in hard and soft corals, emerging from the surrounding sandy bottom at 18–25 metres and rising to its shallowest sections at 8–12 metres. The reef is large enough to constitute a full dive experience on its own, and experienced divers describe it as having sufficient complexity that the same diver experiences new things on repeated dives.
Best Time to Dive
December to April is the peak season for Pilot Reef, with dive slots from 5:10am to 11:30am. The site's northeast-facing position makes it more affected by northeast monsoon swells between October and December than the more sheltered sites, but it can be accessible from October onward in calm conditions. Visibility typically reaches 15–25 metres in season. Water temperature stays 25–29°C year-round.
Marine Life at Pilot Reef
The northern section of the reef (8–15m) is where Pilot Reef's complex topography becomes a macro observation challenge. Scorpionfish, flatheads, and stonefish are very common here but a challenge to spot amidst the complex topography — therein lies the fun. The encrusting and digitated coral formations covering the northern rock face create a layered surface with no obvious visual depth cues, and camouflaged animals blend completely against it, revealed only by patient, systematic observation.
Crawfish, prawns, and shellfish occupy the crevices throughout this section. Octopuses shift colour behind rocks, ghost pipefish hide in the coral branches, and nudibranchs move across the surfaces in vivid colour. Running beneath the main reef structure is a 25-metre canyon strip, a sheltered corridor where the reef overhang creates a lower-light environment distinct from the open reef above. This canyon is a natural cleaning station: groupers and sweetlips descend from the reef to specific positions on the canyon floor, where cleaner shrimps and wrasse attend to them, removing parasites in a symbiotic exchange visible in real time.

FAQs
The phantom bannerfish wall is a dense schooling formation of phantom bannerfish that hovers at 8 metres. Phantom bannerfish are strikingly patterned fish with black-and-white vertical banding and a long trailing dorsal fin, and the formation at this site consists of dozens to hundreds of individuals hovering in a close-packed group rather than loosely scattered.
Yes, leopard shark and zebra shark are common names for the same species at different life stages. Juveniles have a bold zebra-like black-and-white banding pattern, which gives them the name "zebra shark." As they mature into adults, the banding breaks up into a spotted brown-and-cream pattern, similar to a leopard's markings, which is why the same animal is called a "leopard shark" in its adult form. Both names are used in the Andamans, and at Pilot Reef you may encounter both juveniles and adults depending on the season.
Pilot Reef requires a minimum Open Water certification. The site's depth range is entirely within the OW certification depth limit, and the lack of strong current at this site makes it manageable for OW-certified beginners with reasonable buoyancy control. That said, Pilot Reef is not ideal for a newly certified OW diver who has never dived here independently before. The complex topography can be disorienting for divers who are still developing their navigation skills, and the macro life requires buoyancy precise enough to hover stationary at close range without disturbing the reef.
Scorpionfish blend into the reef, octopuses play hide and seek among the rocks, and nudibranchs parade across coral surfaces. The specific quality that makes Pilot Reef productive for macro photography is the combination of species density and topographic complexity, which rewards divers who move slowly and look carefully rather than covering distance.
Certified divers (Open Water or above) pay INR 3,500 + 18% GST per person.
Your dive includes a scuba tank, 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, surface marker buoy, rash guard, and dive computer are optional extras worth carrying if you have them.
