About This Place

An underwater trail of nine stops covering twelve WWII craft: Japanese shipwrecks including the presumed Shoan Maru (locally called the Chinsen), landing craft, a U.S. LVT, four downed aircraft including the Kawanishi "Emily" flying boat, and three semi-submerged Sherman tanks within swimming distance of the Oleai and Susupe beaches. Open to the public year-round and free; go with a local dive or snorkel operator. Submerged heritage is protected — look, do not touch or remove.
