Many of the wrecks are visible while snorkelling and there are many on-shore wartime locations to visit.
The warm, tropical waters and prolific marine life has transformed the wrecks into artificial reefs and beautiful coral gardens.
Chuuk Atoll, (also Known as Truk) in the Caroline Islands is infamous for its giant lagoon. The lagoon is the final resting place for more than 100 ships, planes and submarines - the legacy of a fierce World War II battle between the Imperial Japanese Fleet and Allied carrier planes.
Nowhere else in the world are there so many wrecks in close proximity, situated in shallow clear water. The lagoon has been declared an underwater museum and souvenir taking of relics from the area is prohibited by law.
The majority of the wrecks lie off DubIon, Eten, Fefan and Uman Islands and represent the largest naval loss in history. Their cargoes of tanks, trucks, airplanes, mines, bombs, machine gun bullets and thousands of other artefacts including beautiful china are there still to be explored.
