Chuuk (ex Truk)

Chuuk Lagoon, also previously known as Truk Lagoon is one of the four states of the Federated States of Micronesia. The cluster of 16 much-eroded volcanic islands have mangrove swamps along their coasts with rich rainforests in the central mountainous areas. The islands are hugely popular with scuba divers thanks to the incredibly interesting shipwrecks which have become foundations for new reef growth.
