Fakarava
Fakarava is a UNESCO Biosphere Reserve in the Tuamotu Archipelago — a low coral atoll with two legendary passes that funnel Pacific water and pelagic life through its lagoon. This is advanced drift-diving territory: Garuae Pass in the north is the widest channel in French Polynesia, where incoming tides can stack grey reef sharks, Napoleon wrasse, and occasional great hammerheads along the drop-off. Tumakohua Pass in the south is the famous "shark wall" — during June–July grouper spawning around the full moon, hundreds of grey reef sharks hang in the blue like a living curtain. Visibility routinely clears 30–50 m in the dry season, and the outer walls still carry healthy hard-coral cover that feels untouched compared to busier Indo-Pacific hubs. Beyond the passes you get canyon dives (Alibaba), manta cleaning stations on Ohotu-side walls, lagoon blues at Tetamanu, and humpback whales overhead in August–October. Most divers base in Rotoava for Garuae access or split the trip with a few nights at Tetamanu village for South Pass — plan around tides, not just calendars.
Rangiroa
Rangiroa is the largest atoll in French Polynesia — a thin coral ring around a lagoon big enough to swallow Tahiti — and its diving reputation rests almost entirely on two ocean passes: Tiputa and Avatoru. Tiputa is the headline: inbound tides stack grey reef sharks along the drop-off, dolphins cruise the channel year-round, and in January–March the deep mouth of the pass is where great hammerheads show up for divers who can handle 40–50 m profiles. Avatoru is narrower and shallower, known for silvertip sharks, mantas feeding against the flow, and colorful reef pockets once you drop into the "small pass." Visibility in the dry season routinely clears 30–50 m; water sits around 26–29°C. Every signature dive is tide-timed — operators run Tiputa on the morning inbound window, then often put dolphin or Aquarium tanks in the afternoon. Most divers base on the Avatoru–Tiputa motu strip (airport on Avatoru; Tiputa village needs a boat). This is Tuamotu pass diving, not a beginner reef circuit — lagoonside Aquarium works for newer divers, but Tiputa drift is why people book the Air Tahiti hop from Papeete.
