Grande Island Goa: Diving, Boat Tours, and Trip Guide.

Grande Island (also known as Ilha Grande) is an uninhabited island located in the Arabian Sea, approximately 5.6 to 10 kilometres off the coast of Mormugao taluka in South Goa (coordinates 15°20'58" N, 73°46'32" E). It is the central hub for open-water recreational diving, snorkeling, and boat excursions in Goa.

Because the island has no public ferry connections or civilian landing infrastructure, all visits take place through authorized commercial day-boat tours and guided charters. The island is under the security control of the Indian Navy, meaning civilian movement is restricted to surrounding waters, anchored boats, and limited beach landings at Monkey Beach. Overnight stays and camping are strictly prohibited.

This guide outlines mainland boat departure points, transit schedules, scuba diving and snorkeling package costs, dive site depths, safety rules, and season details to help you organize a day trip.

Mainland Departure Jetties and Transit Times

Commercial day trips to Grande Island depart from designated jetties across North, Central, and South Goa. Most tour boats depart mainland jetties between 7:30 AM and 9:30 AM and return between 3:00 PM and 5:30 PM. Local maritime guidelines require commercial boats to exit the island's waters by late afternoon, typically wrapping up on-water activities between 8:00 AM and 3:30 PM.

Travel times vary significantly depending on your mainland departure jetty. Boats departing from Mormugao Harbour or Baina Beach in South Goa reach the island in 20 to 30 minutes (or up to 45 to 60 minutes depending on sea conditions). Departures from North Goa jetties, including Sinquerim and Coco Beach, take between 45 and 90 minutes. You can plan road transport to your jetty using our transit guide.

During the journey across the mouth of the Mormugao and Zuari waters, boat crews routinely navigate along routes known for sightings of Indo-Pacific humpback dolphins. Under Captain of Ports and Goa Tourism regulations, all passengers traveling on open passenger boats must wear certified life jackets for the entire journey.

Dive Sites and Marine Life Around Grande Island

The reefs, pinnacles, and wrecks surrounding Grande Island make up Goa's most prominent diving area. Water depths range from shallow sheltered bays suited for snorkelers to open-water pinnacles subject to strong currents.

Shelter Cove (also known as Coral Garden) sits northeast of the island. It features a sandy and gravel seabed with depths between 4 and 8 metres, hard corals, and minimal currents, making it the primary site for beginner scuba dives and snorkeling. Other nearby reefs include Bounty Bay, Uma Guma Reef, and Turbo Tunnel.

For more advanced divers, Sail Rock is an open-water pinnacle located southwest of the island. Depths drop from 16 to 24 metres, where surging water movements attract pelagic species such as barracudas, groupers, and rays. Marine life documented across Grande Island's reefs includes butterflyfish, schooling bannerfish, moray eels, surgeonfish, pufferfish, scorpionfish, and sea cucumbers.

Shipwrecks of Grande Island

The waters off Grande Island and nearby Sunchi Reef served as Portuguese maritime anchorages and defensive channels outside the Zuari estuary from 1510 until 1961. Marine archaeologists from the National Institute of Oceanography (NIO) have documented multiple historic shipwrecks here, including a 19th-century cargo vessel that sank carrying terracotta roof and floor tiles from the Basel Mission Tile Works of Mangaluru.

The most frequented modern wreck site is Suzy's Wreck, located off the southwestern edge of the island. It consists of the broken steel hull of the SS Rita, a British cargo ship that grounded during a storm in the 1950s. The wreck rests in 3 to 13 metres of water and is accessible to both beginner and intermediate divers.

Davy Jones' Locker sits roughly 600 metres south of Suzy's Wreck at depths between 14 and 18 metres. This site contains the severed stern and engine machinery of the SS Rita. Because of strong bottom currents and greater depth, it is recommended for certified divers.

Best Season and Underwater Visibility

The operational season for boat trips and water activities around Grande Island runs from October to May. All boat trips and diving operations are suspended annually from June through September due to rough southwest monsoon sea conditions and the mandatory marine fishing and navigation ban. For more on seasonal weather patterns, consult our guide on the best time to visit Goa.

Underwater visibility around Grande Island ranges between 3 and 12 metres depending on the tidal cycle and weather. The clearest visibility (typically 5 to 12 metres) occurs during the winter window from November to February, when sea conditions are calmest. To pair an island day trip with mainland monuments and landmarks, review our Goa sightseeing guide or plan an organized South Goa sightseeing tour.
