Minerva Ledge — Discovered by Jacques Cousteau at Havelock Island (Swaraj Dweep)
Minerva Ledge carries a piece of diving history few other sites can claim: it was discovered in 1970 by Jacques Cousteau, the pioneering French oceanographer, during his exploration of the Andaman Islands. Located 18 kilometres east of Havelock Island, it remains one of the most respected dive sites in the region more than five decades later.
Minerva Ledge is a vast reef that simply cannot be explored in a single dive. Its signature topography is a series of flat coral gardens, and strong currents running across the site make it one of Havelock's most popular hotspots for drift diving — a style where divers move with the current rather than against it, covering long stretches of reef with minimal effort.
Overview of Minerva Ledge (Quick Facts)
About Minerva Ledge Dive Site
In 1970, Jacques Cousteau discovered Minerva Ledge during his exploration of the Andaman Islands — a fact that has given this site a distinctive place in Havelock's diving history ever since. Cousteau's expeditions across the world's oceans in the mid-20th century helped popularise recreational scuba diving itself, and his personal discovery of this reef lends Minerva Ledge a legacy that few other Andaman dive sites can match.
The site is a very large dive site — large enough that it can't be explored on a single dive. Its signature topography is a series of flat coral gardens spreading across the reef, and strong water currents running across the site make it a popular hotspot for drift diving, drawing intermediate and advanced divers who want to cover long stretches of reef in a single, current-driven dive.
Topography
Minerva Ledge is a large reef with a depth that fluctuates between 12 and 24 metres depending on the section being dived. The flat coral gardens that define much of the reef's character sit across this depth range, offering divers different sections and different sightings depending on which part of this expansive site they explore on a given dive.
Best Time to Dive
December to April is the best season for Minerva Ledge, with dive slots from 5:10am to 11:30am. Water temperature stays 26–29°C year-round.
Marine Life at Minerva Ledge
Regularly spotted species at Minerva Ledge include Oriental sweetlips, angelfish, surgeonfish, triggerfish, and butterflyfish across the flat coral garden sections. Banded sea kraits are a frequent sighting, along with green turtles resting on the reef or gliding through the current. Eagle rays pass through the open water, while juvenile fish shelter among the coral formations. Schools of snappers, unicornfish, and fusiliers move through the water column in coordinated groups, and giant groupers hold position near larger coral and rock formations throughout the reef.
Occasional sightings at this site include mobula rays and other ray species, sea turtles beyond the regularly seen green turtles, and sharks — white-tip reef sharks, nurse sharks, and cat sharks have all been recorded here, though none should be considered a guaranteed encounter. The reef's coral population is a mixture of soft and hard corals, with nudibranchs a popular find for divers who take the time to look closely at the reef surface between the site's larger coral garden sections.

FAQs
Yes. Jacques Cousteau, the pioneering French oceanographer and co-inventor of the modern Aqua-Lung, discovered Minerva Ledge in 1970 during his exploration of the Andaman Islands. It's a genuine piece of diving history that few other sites in the region can claim, and one of the reasons the site has held a special reputation among Havelock's dive community ever since.
Minerva Ledge experiences strong water currents that run consistently across the reef. Rather than fighting the current, divers here drift with it, covering more of the reef with less physical effort while the current carries them past a continuous succession of coral formations and marine life. This drift-diving style requires comfort with current, good buoyancy control, and the ability to follow a guide's lead on positioning, which is why the site is reserved for Intermediate and Advanced certified divers.
No. Minerva Ledge is a very large dive site that cannot be fully explored in a single dive. Divers who want to see more of the reef's flat coral gardens and varied sections typically return for multiple dives across different visits, with each dive covering a different stretch of the reef depending on the current and the day's dive plan.
Minerva Ledge is suitable for Intermediate and Advanced certified divers. The combination of depth (12-24 metres) and the site's strong currents means it isn't recommended for newly certified Open Water divers on their first few dives; a solid comfort level with buoyancy control and drift conditions is expected.
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.
