Pakin Atoll, the second and more distant of Pohnpei’s two satellite atolls, offers excellent advanced-level diving for those willing to make the 90 min-2 hr trip and brave the sometimes rough conditions in the crossing. All dives are drifts along the vertical outer walls of Pakin’s barrier reef, which is riddled with tunnels, caves, and holes. Like And Atoll, Pakin’s sites are known for large pelagic species, very healthy coral life, and lots of sharks and turtles. Visibility is some of the best — exceeding 60 meters. Pakin has five marine protected areas which require a permit for entry.
