Tumakohua, the southern pass into Fakarava’s lagoon, holds a resident aggregation of grey reef sharks counted in the hundreds. The "wall of sharks" is a literal description: a bank of them facing into the current across the pass at 25 to 30 m, holding position without effort while divers work to stay still. It is dived on the incoming tide as a drift that ends inside the lagoon, and on the outgoing it is not dived at all. In June and July the camouflage grouper spawn here and the aggregation swells further. Fakarava is a UNESCO biosphere reserve, and this is one of the few places on earth where a shark population has simply been left alone long enough to show what normal looks like.

Fly Papeete to Fakarava, then an hour by boat down the atoll to the south pass, or join a liveaboard working the Tuamotus.

Best season

  • ExcellentJun–Jul
  • GoodAug–May

Before you get in

  • Past 30 m, where no-stop time and gas both go quickly and nitrogen narcosis starts to show.
  • Recorded as a site with strong current. Settle your gas reserve, when you would call the dive, and your surface signal before you get in.
  • A drift dive: you do not come back to where you went in, so boat pickup and an SMB are part of the plan rather than extras.

Taken from this site’s recorded depth, type and current, and nothing else. An empty list is not a safe site — the sea on the day, the local geography and the boat traffic are not in it. The briefing on the spot comes first.
