Fakarava is a UNESCO Biosphere Reserve atoll in French Polynesia's Tuamotu Archipelago, famous for the South Pass 'wall of sharks'—one of the world's densest grey reef shark aggregations, estimated at around 700 individuals—and for the June–July marbled grouper spawning that turns the channel into a high-energy predator arena.

Description
Fakarava is the second-largest atoll in French Polynesia's Tuamotu Archipelago, a 60 km by 21 km ring of coral enclosing a 1,112 km² lagoon. Its surrounding commune has been a UNESCO Biosphere Reserve since the reserve's 1977 creation (extended to the seven-atoll Commune de Fakarava reserve in 2006), and the South Pass (Tumakohua, by Tetamanu village) has been a protected no-take zone since 2008. That protection produced the atoll's signature spectacle: a resident school of grey reef sharks—documented at up to roughly 700 individuals in a 17-hectare area—holding station against the incoming current in a dense 'wall of sharks.' Diving here is pass diving: the lagoon's only two connections to the ocean are the South Pass and the much larger North Pass (Garuae, ~1.4 km wide, the largest pass in French Polynesia), so tidal exchange drives strong drift currents best dived on the incoming tide. Every June and July, several days before the full moon, more than 17,000 camouflage (marbled) groupers gather to spawn in the South Pass, drawing the sharks into a feeding frenzy. Water is warm (about 26–29°C) and visibility often exceeds 30 m, with a 3 mm suit usually sufficient.
Highlights
What makes this dive worth the trip.
Fakarava's South Pass holds one of the largest reef-shark aggregations on Earth: a peer-reviewed acoustic-telemetry study documented up to about 700 grey reef sharks (Carcharhinus amblyrhynchos) within a 17-hectare area of the pass, the so-called 'wall of sharks.'
Every June and July, in the days before the full moon, more than 17,000 camouflage (marbled) groupers (Epinephelus polyphekadion) aggregate to spawn in the South Pass—grouper begin arriving about two weeks before the full moon and nearly all leave within 48 hours of spawning—drawing the resident sharks into a feeding frenzy.
Fakarava's surrounding commune is a UNESCO Biosphere Reserve—part of the reserve first created in 1977 and extended in 2006 to the seven-atoll Commune de Fakarava reserve covering roughly 1.99 million hectares (the vast majority of it marine area).

Tumakohua (South Pass) — Wall of Sharks
The signature dive of Fakarava and the reason most divers come: a protected no-take pass at the south end of the atoll, near Tetamanu village, holding a resident school of grey reef sharks documented at up to roughly 700 individuals. Dives are timed for the incoming tide, drifting in from the ocean side and pausing in a natural grotto or behind a coral ridge to watch the sharks hold station against the current—'the horizon covered with shark fins.' Beyond the sharks, divers see Napoleon wrasse, barracuda, marbled groupers, and schooling jacks over rich coral. In June and July the marbled grouper spawning aggregation turns the pass into a high-energy predator arena.

Garuae (North Pass)
The largest pass in French Polynesia, roughly 1.4 km wide, near the main village of Rotoava. This is a big, fast drift dive performed on the incoming tide: divers drop onto the outer reef and ride the current through the channel at 25–40 m, often covering close to a mile. Grey reef sharks are resident in numbers, with typical dives producing dozens of shark sightings, while the sandy floor's coral bommies act as cleaning stations for mantas and pelagics. Hammerheads appear seasonally and silvertip sharks, dogtooth tuna, and Napoleon wrasse are regular. Strong currents and depth make this an advanced, drift-experienced dive.

Tetamanu Village Reef
A shallow, sheltered dive and snorkel area just inside the South Pass at Tetamanu, used as a relaxed second dive after the wall of sharks. The shallow coral gardens and pass margins teem with reef fish, juvenile blacktip reef sharks patrol the sandy shallows, and whitetip reef sharks rest on the bottom. Calmer conditions here make it the gentlest diving in the South Pass area, suitable as a decompression-stop reef and for less experienced divers, with frequent green turtle sightings over the coral.

Ohotu Corner (North Pass exit)
The eastern exit point of the Garuae North Pass, where the incoming drift dive typically finishes as divers are carried out of the channel into the lagoon. The corner aggregates grey reef sharks and large schools of jacks and barracuda that hold in the lee of the current, and Napoleon wrasse patrol the coral edge. It is the calmer end of the North Pass profile, where divers regroup in shallower water after the fast central drift, often with sharks still circling.

Ali Baba / Shark Hole (South Pass)
A deeper section of the South Pass below the main shark wall, named for the natural amphitheatre where the grey reef shark school packs most densely. Divers descend along the pass wall to around 25–30 m and shelter behind coral outcrops to watch hundreds of sharks stacked in the current, with marbled groupers, jacks, and Napoleon wrasse mixed in. During the June–July grouper spawn this is the focal point of the predator action. Deeper and more current-exposed than the shallow Tetamanu reef, it is reserved for experienced divers.
