This dive site, Tetamanu (Tumakohua) Pass in Fakarava Atoll, French Polynesia, is a world-renowned UNESCO Biosphere Reserve famous for its spectacular "wall of sharks." As a pass connecting the open ocean to the lagoon, it's primarily experienced as a drift dive, with divers typically entering on the ocean side and allowing the incoming or outgoing current to carry them through the pass into the calmer lagoon. There is no specific historical story provided for the dive site itself, but its natural formation and rich biodiversity are the main attractions.
The vibrant coral reefs within the pass and surrounding areas host an incredible array of marine life. Divers and snorkelers can expect to encounter numerous species of sharks, including grey reef sharks and possibly hammerheads or tiger sharks, forming the famous 'wall.' Large Napoleon wrasse are commonly sighted, alongside a myriad of colorful reef fish, creating a bustling and visually stunning underwater ecosystem.
While the specific 'best time' for Tetamanu Pass isn't stated, French Polynesia generally offers excellent diving year-round, with peak shark activity often influenced by moon phases and tides. Divers should be experienced in drift diving and comfortable with strong currents due to the nature of the pass. For snorkelers, the site offers dual experiences: exciting drift snorkeling through the pass during appropriate tidal conditions, and calm, free snorkeling on the shallow reef flats directly from the island shore, making it accessible for various levels.
