Fakarava
Fakarava is a rectangular atoll in the Tuamotu Archipelago of French Polynesia and a UNESCO Biosphere Reserve. It is known for two passes cut through the reef rim. The South Pass (Tumakohua), off the village of Tetamanu, holds a resident aggregation of grey reef sharks that operators and researchers count in the hundreds, commonly cited at 300 to 700 animals. Around the full moon of June or July, roughly 17,000 camouflage groupers gather in the South Pass to spawn, one of the largest documented grouper aggregations anywhere, and shark densities peak as the sharks feed on them. The North Pass (Garuae) is the widest pass in French Polynesia at about 1,600m, dived as a fast incoming-tide drift with a sheltered fish-packed canyon called Ali Baba off to the side. Diving here is drift diving in current, done on incoming tides, and is generally advanced. The South Pass current is more moderate and lets you pause and watch; the North Pass runs stronger, routinely over three knots. Access is by a one-hour Air Tahiti flight from Papeete on Tahiti, with roughly one flight a day, and there is no other way in. It is not a cheap trip.
What makes it special
- South Pass (Tumakohua/Tetamanu) 'wall of sharks' - a resident grey reef shark aggregation commonly counted at 300-700 animals
- Camouflage/marbled grouper spawning of roughly 17,000 fish in the South Pass around the June or July full moon, among the largest documented grouper aggregations
- Garuae (North Pass) - the widest pass in French Polynesia (~1,600m), a fast incoming-tide drift with the sheltered Ali Baba canyon off the main flow
- UNESCO Biosphere Reserve atoll, with diving spread between the North Pass near Rotoava and the remote South Pass near Tetamanu

Price is per person for a typical trip, excluding international flights ($$ $2,000–4,000 to $$$ over $4,000).
French Polynesia is expensive. Air Tahiti Papeete-Fakarava runs roughly $250 each way. Single/two-tank dives at the North Pass with shops like O2 Fakarava or TOPDIVE are premium by global standards, and a full-day trip from Rotoava down to the South Pass (Tetamanu), including lunch, is commonly around $200. Pensions and dive lodges add materially to the total; a week easily lands in the $$$ tier once flights, lodging and diving are combined.
Best time to dive
- Current
- Strong
- Water temp
- 26–29°C (coldest Jun, warmest Jan)
- Visibility
- 20–45m — Commonly 30-40m in the dry season (June-September), occasionally exceeding 45m on calm days. Visibility inside the passes drops on outgoing tides and during the plankton-rich water that draws in spawning activity, so it varies dive to dive.
- Getting there
- Moderate — Reachable but with some friction: 1 domestic flight.
- Experience
- Advanced Open Water with drift experience is the practical minimum. The North Pass (Garuae) runs fast, routinely over three knots, and is only dived safely on the incoming tide. The South Pass current is more moderate and easier to hold position in, and some operators will take capable Open Water divers there with a guide, but AOW plus comfort in current is the sensible bar for the passes.
Nearest airports
- FAV — Fakarava Airport (About a 1h10 Air Tahiti flight from Papeete (PPT) on Tahiti; roughly one flight a day, no flights some weekdays. Papeete is the international hub, reached via Los Angeles, Auckland, Paris and others.)
- PPT — Faaa International Airport (Papeete, Tahiti) (International arrival point for French Polynesia; connect onward to Fakarava on Air Tahiti's Tuamotu circuit (Tahiti-Tikehau-Rangiroa-Fakarava).)

The headline species. The South Pass holds a resident aggregation commonly counted at 300-700 grey reef sharks year-round. Densities peak around the June-July full moon when the sharks feed on spawning groupers. Present at both passes; sightings are reliable but exact numbers vary with tide and season.

Present on Fakarava's reefs year-round but seen singly outside the spawn. The spectacle is the aggregation of roughly 17,000 fish in the South Pass over a few days around the June or July full moon, documented by CRIOBE researchers. Outside that window you may see scattered individuals only.

Bottlenose dolphins visit the passes and can turn up on a dive, but Fakarava is not the reliable dolphin site that Rangiroa's Tiputa pass is. Treat encounters as a bonus, not an expectation.

Dive sites
Worth knowing before you book
- Costly and remote: the only access is a ~1h Air Tahiti flight from Papeete at roughly $250 each way with about one flight a day, on top of already high French Polynesia lodging and dive prices.
- Pass diving means real current. The North Pass regularly exceeds three knots and is dived only on the incoming tide, so dive timing is dictated by the tide table, not your schedule.
- The grouper spawn is a narrow window - a few days around the June or July full moon. It draws more divers and boats to the South Pass, and lodges near Tetamanu book out far ahead.
- Shark density varies with tide, season and site. The 300-700 figures are peak-condition counts; a given dive can show far fewer, and sightings are never guaranteed.
- The South Pass is a long boat trip or an overnight from the North Pass hub at Rotoava, and infrastructure at Tetamanu is limited.

Note on the data: Shark counts (300-700) are operator- and media-reported peak figures corroborated by the CRIOBE/Mourier-Ballesta research at the South Pass; treated as a range, not a per-dive guarantee. Grouper aggregation size (~17,000) and June-July full-moon timing are from peer-reviewed CRIOBE work (Mourier et al., Coral Reefs) and National Geographic/CNRS coverage. Coordinates are approximate atoll-level positions, not surveyed dive GPS. No marine park fee is charged for diving, though the atoll is a UNESCO Biosphere Reserve. Water temperature: Warm tropical water all year, roughly 26-29C, warmest in the Feb-Apr austral summer and coolest around Aug-Sep; there is no meaningful cold thermocline, so the narrow monthly bands are interpolated from published seasonal surface averages. Access: Land-based diving is the norm: after arriving Tahiti (PPT) you take one domestic Air Tahiti flight (about 1h20) to Fakarava, then a short road transfer to Rotoava, with dive centres running day boats to the North and South passes; a few liveaboards also visit, but you do not need one.
