New for 2016, with updated images and wreck site information. These islands in the Federated Sates of Micronesia offer the best wreck diving in the world as well as amazing reefs, deep dropoffs and isolated atolls. Truk Lagoon (Chuuk) was the site of the famous WWII air raid Operation Hailstone that lasted three days and sunk dozens of Japanese ships in the waters of the vast inner lagoon.

Today, they are “shipreefs,” historic wrecks adorned in corals and full of marine life. For history lovers or reef divers, these amazing dives have the potential to overload the senses and exhaust the superlatives of every diver and snorkeler that visits them.

East of Truk are the islands of Pohnpei and Kosrae. Pohnpei has amazing natural beauty above and below the surface, with a mysterious ancient city, many waterfalls, high mountains and a huge barrier reef. Two atolls also lie offshore. Pohnpei diving is famous for mantas, sharks and beautiful corals.

Kosrae is also a legendary natural wonder, with very little coastal development to spoil the extremely healthy hard coral reefs. This is nature at its wild best. Kosrae has natural forests and a very special mangrove dive.
