Kosrae State dive sites

Kosrae is served by United Airlines' Island Hopper route, which connects Honolulu to Guam with stops at several Micronesian islands including Kosrae. Flights typically operate several times per week. From Kosrae's airport near Tofol, the island's single dive operator provides transfers and full diving services. There is no need for onward boat travel as all dive sites are accessible by day boat from the harbour. Accommodation is limited to a handful of small hotels and guesthouses, and advance booking is strongly recommended.

Kosrae's reefs have been spared the major bleaching events and storm damage that have affected much of the tropical Pacific. The island's isolated location, small population of around 6,600 people, minimal coastal development, and absence of significant agricultural runoff have preserved reef health. Additionally, Kosrae established marine protected areas early and enforced fishing regulations effectively. Scientists from the University of Hawaii and other institutions have documented hard coral cover exceeding 90 percent at several sites, making Kosrae's reefs among the healthiest measured anywhere in the Pacific.

Hiroshi Point is suitable for intermediate to advanced divers. The wall descends beyond recreational limits, but the most interesting diving occurs between 10 and 35 metres where coral cover is densest and shark encounters are most frequent. Moderate currents run along the wall, requiring comfort with drift diving techniques. Advanced Open Water certification is recommended, and divers should have experience managing depth on wall dives. The site has no mooring lines, so free descent to the wall top at around 5 metres is standard.
