Kosrae is one of the least spoiled and least developed areas in the Federated States, a laid-back place with an air of innocence. The main island is volcanic with an interior of uncharted rainforests, a pristine fringing reef and a coast that is a mix of sandy beaches and mangrove swamps.
Chuuk (formerly Truk) is colourful, lively and rough around the edges. It comprises 15 main islands, 92 outer islands and over 80 islets in the Chuuk Lagoon.
Its biggest drawing cards are its sunken wrecks, a boon for serious divers. A whole Japanese fleet rests on the lagoon floor, evidence of the largest naval loss in history. Each wreck is a time capsule - some are upright, some intact, some in pieces.
