USAT Liberty

USAT Liberty — Tulamben, Bali, Indonesia

The USAT Liberty is the most accessible major wreck dive in the world. There is no boat. You pull on your fins at the black-sand beach of Tulamben, on Bali's northeast coast, walk into the shallows, and within 30 fin kicks you're swimming over the bow of a 120-meter US Army cargo ship.

The History

The Liberty was a US Army supply vessel torpedoed by a Japanese submarine on 11 January 1942 in the Lombok Strait. The crew survived and the ship was taken in tow, but she was too damaged to save and was beached at Tulamben. She sat on the beach until 1963, when the eruption of Mount Agung — Bali's highest volcano — shook her off the slope and she slid into the sea, breaking apart as she went. Today she lies on a slope from 5 to 30 meters, oriented roughly parallel to the shore, with her hull split open and all her internal structure accessible.

What Six Decades of Marine Growth Has Produced

The Liberty has been underwater for over 60 years and it shows — in the best possible way. The wreck is now one of the most densely marine-life-encrusted dive sites in Bali, possibly in all of Indonesia. Bumphead parrotfish school over the stern in groups of 50 or more, grinding the coral with their fused beaks and defecating white sand clouds. Hawksbill and green turtles rest on the deck railings so frequently that they've almost become furniture. Giant barracuda hang in formation at the bow. At least six species of nudibranch can be found on a single dive.

Inside the holds: pygmy seahorses on gorgonian fans, ghost pipefish in the coral growth, leaf scorpionfish hiding in plain sight. The engine room is penetrable for experienced divers. The cargo holds are covered in lettuce coral and black coral trees that have made them unrecognizable as industrial space.

At night, the wreck transforms — Spanish dancer nudibranchs emerge, moray eels leave the crevices to hunt, and the fish life reorganizes entirely.
