The Legendary USAT Liberty Wreck

Walk off the volcanic beach and into history. Explore 120 meters of steel reclaimed by the ocean, resting just steps from the Tulamben shoreline.

Tulamben — A Shipwreck Frozen in Time

The USAT Liberty isn't just a dive; it's an immersion into a thriving artificial reef. Once a WWII cargo ship, it was torpedoed in 1942 and eventually pushed into the depths by the 1963 eruption of Mount Agung. Today, it stands as Bali's most iconic dive site.

Imagine a 120-meter ghost ship resting on a black sand slope, covered in soft corals and giant sea fans. Because it starts at just 5 meters and drops to 30 meters, the sunlight penetration is incredible, making it a dream for both wide-angle photographers and those looking for their first wreck experience. The shore entry is the defining feature—you gear up on the beach and walk over smooth volcanic pebbles directly into the blue.

Tactical Highlights

The Human Detail: Historical Context

The USAT Liberty was built in 1918. During its final voyage, it was carrying rubber and railroad ties when it was hit by a torpedo from the Japanese submarine I-166. It didn't sink immediately; it was towed toward Singaraja but began taking on too much water and was beached in Tulamben. For 21 years, it sat on the shore until the devastating eruption of Mount Agung in 1963 slid the vessel into its current underwater position. This history is palpable as you swim through the twisted steel beams now encrusted in life.

Professional Tip

The wreck is huge. Don't try to see it all in one dive. Spend your first dive exploring the exterior and the bow, and save the swim-throughs and the stern for your second descent. If you are a macro lover, the cargo hold is a goldmine for nudibranchs.
