Truk Lagoon


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. The lagoon has been declared an underwater museum. Souvenir taking of relics from the area are prohibited by law.

Nowhere else in the world are there so many wrecks in close proximity, situated in shallow clear water. Many of the wrecks are visible while snorkelling and there are many on-shore wartime locations to visit.

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.

The warm, tropical waters and prolific marine life has transformed the wrecks into artificial reefs and beautiful coral gardens. The main island of Weno (formerly Moen) is the capital and commercial centre.

  • Geographical Information

    The many islands within this huge atoll are crowned with natural beauty. The outer barrier reef is punctuated with idyllic sand spits dotted with coconut palms. The high volcanic islands in the central lagoon rise into the blue island skies. Many of the islands offer fertile soils, abundant water and lush vegetation that harbours rare and migratory birdlife. Wild orchids and other flora are found in the scenic and sometimes rugged terrain of the islands




  • Activities

    There are many fascinating and historic sites to visit in and around Chuuk. Snorkel or scuba dive in this maritime museum, spend the night on a small island, go on a fishing expedition with experienced local guides, or simply relax on a sandy beach or rent a kayak or scooter to get a view of life in Chuuk. For the best views of the lagoon, climb the old Sapuk Lighthouse, built during the Japanese occupation.

  • When to Travel to Truk

    Chuuk's tropical oceanic climate is consistently warm and humid, with some of the most uniform year-round temperatures in the world. Most days it is around 27°C. Some days it gets up to 32°C and sometimes the temperature may drop to 21°C. It is a little drier, cooler and breezier between December and April. The wettest months are October and November. Typhoon season is between August and December but Chuuk rarely gets a direct hit from a typhoon.

    The sheltered waters of Truk Lagoon provide a most comfortable dive location with the water temperature normally between 28-29°C, no thermoclines or currents and good visibility between 12 - 30 metres.
