Manihi — a ring shaped atoll that forms a lagoon perfect for SCUBA and black pearl farming. With only 400 local inhabits working at either the pearl farms or the single resort. This destination is truly at the edge of the world.
Fakarava — also great for diving. It has 2 passes, the north Garuae pass and the south Tumakohua pass. Both are quite far away from each other, but local dive operators will take you there. Sharks are aplenty in the south pass of Fakarava!
Rangiroa — one of the largest atolls in the world, and the most populous island in the Tuamotus. Very popular with SCUBA enthusiast and those looking to get away from civilization.
Tikehau — one resort, plus great diving and birding.
