Fuvahmulah is a single-island atoll in the far south of the Maldives, near the equator, whose reef drops straight into water exceeding 2,000 m and draws pelagics to within recreational depth. It is the world's most reliable tiger-shark destination, hosting the largest documented aggregation of the species on Earth alongside pelagic threshers, scalloped hammerheads, oceanic mantas and whale sharks.

Description
Fuvahmulah (administratively Gnaviyani Atoll) is one of only two single-island atolls in the Maldives, a roughly 5 km-long oceanic platform reef with no lagoon, sitting just south of the equator about 500 km south of Malé. Its fringing reef plunges almost vertically to depths beyond 500 m, and the surrounding open Indian Ocean exceeds 2,000 m, so currents and upwelling deliver large pelagic species onto reefs shallow enough for ordinary scuba. The island's defining draw is its resident tiger sharks (Galeocerdo cuvier): a 7-year peer-reviewed photo-ID study (December 2016–September 2023) identified 239 individuals from 788 surveys, the largest tiger-shark aggregation documented anywhere, and a population that is 84.5% female with strong site fidelity by gestating adult females. The sharks were habituated over generations by the local tuna fishery, whose fish-waste discards at the harbour still anchor the daily dives at Tiger Harbour. Beyond tigers, Fuvahmulah is the only known pelagic-thresher (Alopias pelagicus) cleaning station in the Western Indian Ocean, hosts seasonal scalloped-hammerhead and oceanic-manta aggregations, and receives whale sharks, silvertips, grey reef sharks and the occasional mola mola, oceanic whitetip and sailfish. Dives are mostly shallow drift or plateau dives but the exposed, oceanic setting means strong currents and big-animal awareness; it is an advanced, pelagic destination rather than a calm-lagoon one.
Highlights
What makes this dive worth the trip.
A peer-reviewed 7-year study (December 2016–September 2023, 788 dive surveys) using non-invasive photo identification and laser photogrammetry identified 239 individual tiger sharks (Galeocerdo cuvier) at Fuvahmulah — the largest documented tiger-shark aggregation on Earth — with 6,035 encounters and one individual sighted 128 times.
The aggregation is strongly female-dominated (84.5% female; 202 females to 37 males), and adult females show strong site fidelity with a modelled residency of about 61 days, gestating near the island — making Fuvahmulah a conservation 'bright spot' and a likely tiger-shark reproductive area.
Fuvahmulah is recognised as an Important Shark and Ray Area (ISRA) qualifying on multiple criteria — six threatened species, tiger-shark gestation, whitetip-reef-shark resting and reproduction, seasonal oceanic-manta aggregations, and the only known pelagic-thresher (Alopias pelagicus) cleaning station in the Western Indian Ocean.

Dive sites
5 signature sites at this destination.
Tiger Harbour (Tiger Zoo)
The signature dive of Fuvahmulah and the centre of the world's largest tiger-shark aggregation, a horseshoe-shaped sandy plateau just outside the main fishing harbour, an approximately one-minute boat ride from shore. Divers settle on a flat sandy bottom at around 8–12 m while tiger sharks (Galeocerdo cuvier) — habituated over generations by the local tuna fishery's fish-waste discards — circle at close range, often joined by silvertips. Dives are baited and conducted within timed slots allocated to each dive centre to manage crowding; guides enforce strict safety protocols and there are no recorded shark attacks on divers at the site.

Farikede
A spur reef on the south-eastern side of the island that extends roughly 2 km offshore, where the top reef sits around 15–20 m and the wall drops steeply into the blue. The most reliable big-pelagic drift dive on Fuvahmulah: strong oceanic currents bring thresher sharks, silvertips, grey reef sharks, schooling barracuda and giant trevally, with seasonal scalloped hammerheads, oceanic mantas, whale sharks and the occasional mola mola cruising the drop-off. An advanced site that demands good drift-diving skills.

Thoondu
A site off the northern end of the island near Thoondu beach, with a shallow top reef around 5 m sloping to a mid-reef at 15–35 m. Currents are usually small to medium but can occasionally pick up. It is one of the more versatile sites, holding thresher sharks, silvertips and snappers, with seasonal visitors including oceanic mantas, mola molas, scalloped hammerheads and whale sharks passing along the drop-off.

Hoadhadhi (Neregando)
An exposed reef on the western flank of the island with a shallow top reef around 5–8 m dropping to a mid-reef at 15–30 m, swept by medium to strong currents. A drift dive holding whitetip reef sharks, schooling giant barracuda, dogtooth tuna, wahoo, silvertips and giant trevally, with seasonal thresher sharks, oceanic mantas and whale sharks moving through. The current and oceanic exposure make it an advanced-leaning site.

Rasgefannu
A calm, shallow reef on the sheltered side of the island with the top reef around 5 m and a mid-reef to roughly 15–25 m, where currents are almost non-existent. With little flow it is the gentlest of the regularly dived sites and is also suitable for snorkelling; it holds schooling batfish, fusiliers, anemones and lobsters, with thresher sharks among the larger visitors.
