Explore the legendary USAT Liberty wreck in Tulamben, where history meets marine life in one of the world's most accessible and spectacular wreck snorkeling experiences.

USAT Liberty Wreck: Bali's Most Famous Underwater Adventure

USAT Liberty Wreck: Where History Lives Beneath the Waves

The USAT Liberty wreck in Tulamben stands as one of the world's most famous and accessible wreck sites, offering an extraordinary underwater experience that combines fascinating World War II history with spectacular marine life. This 120-meter cargo ship, resting just meters from the shore, has transformed from a wartime casualty into a thriving artificial reef that attracts snorkelers and divers from around the globe.

The Story of USAT Liberty

Wartime History

The USAT Liberty was a United States Army Transport ship built in 1918. On January 11, 1942, while carrying rubber and railway parts from Australia to the Philippines, the ship was torpedoed by the Japanese submarine I-166 in the Lombok Strait. Though severely damaged, the Liberty was towed to the safety of Tulamben's beach by the USS Paul Jones.

From Beach to Reef

Initially beached on Tulamben's shore for salvage operations, the Liberty remained there for over 20 years. In 1963, the massive eruption of Mount Agung shook the ship back into the sea, where it settled in 5-30 meters of water, perfectly positioned for easy access from the shore. This natural repositioning created one of the world's most accessible wreck sites.

Transformation into Artificial Reef

Over the decades, the USAT Liberty has been colonized by an incredible variety of marine life, transforming from a steel wreck into a vibrant artificial reef. The ship's structure provides shelter and breeding grounds for countless species, creating one of Bali's most biodiverse underwater ecosystems.

The Snorkeling Experience

Easy Shore Access

Unlike most wreck sites that require boat trips, the USAT Liberty is accessible directly from Tulamben's black volcanic sand beach. The wreck lies just 25-30 meters from shore, making it perfect for snorkelers of all experience levels. The gentle entry and calm conditions create ideal circumstances for exploring this underwater museum.
