Key Dive Site Facts
Dive Site Overview
For divers exploring Bali's underwater realm, the USAT Liberty wreck stands as a foundational dive site, continuously attracting global interest since the 1980s. Resting peacefully off Bali's northeast coast, its location close to shore allows for excellent accessibility, accommodating various diver skill levels.
Ship's structure, largely fragmented by a 1963 volcanic eruption and the passage of time, now lies scattered across a sandy slope. Despite its broken state, numerous identifiable mechanical components remain, offering compelling points of exploration. Divers regularly encounter boilers, ladders, and valves, each section contributing to the site's rich historical narrative and thriving ecosystem.
Parts of the vessel begin at a depth of merely 5 m (16 ft), extending down to approximately 28 m (92 ft) at its deepest sections, providing extensive opportunities for both recreational and advanced divers. Its sprawling nature encourages exploration of different areas over multiple dives, revealing how ocean life has thoroughly reclaimed the wartime relic.
Best Time to Dive
Planning a dive at the American Tanker benefits from understanding seasonal patterns, with 'Good' conditions typically reported during April and June. April generally offers pleasant atmospheric conditions, with air temperatures averaging near 27.8°C (82°F). Rainfall volumes tend to be lower then, accompanied by moderate wave heights, recorded at about 1.14 m (3.7 ft). June also maintains comfortable air temperatures, approximately 27.9°C (82°F), and brings the calmest wave conditions, averaging 0.88 m (2.9 ft), even with slightly increased average rainfall compared to April. While specific water temperature data isn't consistently available for the immediate site, waters across this region remain warm year-round, ensuring comfortable diving regardless of the season. Divers can explore the wreck outside these peak months, though conditions might vary and generally fall into a 'Moderate' rating for overall experience.

Dive Experience & Conditions
The USAT Liberty wreck is quite accessible, making it suitable for divers with various certification levels. Its proximity to the shore allows for straightforward entry, often as a beach dive. The wreck stretches from shallow depths of 5 m (16 ft) down to its deepest sections at around 28 m (92 ft), providing ample opportunities for exploration. While the visibility varies depending on conditions, it is generally rated as good, allowing for clear views of the extensive wreckage and its marine inhabitants. The fragmented nature of the ship means divers can navigate through various sections, observing the impact of time and the ocean on its structure.
Dive Difficulty & Safety Guidelines
Diving the American Tanker requires adherence to standard wreck diving protocols, particularly given its historical and fragmented nature. While much of the wreck is within recreational limits, those intending to explore the deeper sections, approaching 30 m (100 ft), should hold an Advanced Open Water certification or equivalent. Maintaining excellent buoyancy control is crucial to protect the delicate marine growth covering the wreck and to avoid stirring up silt, which can reduce visibility. Always dive within your training and comfort limits, and consider diving with experienced local guides who know the site's layout.
