USAT Liberty Wreck Diving Guide: Explore Tulamben’s Underwater History

Off the northeast coast of Bali, a century-old shipwreck rests on a slope of black volcanic sand. Now covered in coral and surrounded by marine life, the USAT Liberty is one of Tulamben’s most iconic dive sites.

Located only around 40 metres from shore, the wreck stretches from shallow water to approximately 30 metres. This unusual depth range makes it rewarding for newly certified divers, experienced divers and underwater photographers alike. Whether this is your first wreck dive or your next photography adventure, the USAT Liberty wreck deserves more than one visit.

From Cargo Ship to Living Reef: The History of USAT Liberty

Built in 1918, USAT Liberty later served as a United States Army cargo vessel. In January 1942, it was struck by torpedoes from a Japanese submarine near the Lombok Strait. Severely damaged, the ship was towed toward Bali and eventually beached at Tulamben.

In 1963, seismic activity and waves associated with the eruption of Mount Agung pushed the vessel into the sea. Over the following decades, corals, sponges and sea fans colonised its structure, turning the former transport ship into a thriving artificial reef.

Today, the approximately 120-metre vessel lies on its starboard side along Tulamben Bay’s volcanic slope. Although parts of the structure have collapsed over time, many large features remain visible.

How Deep Is the Liberty Wreck?

The wreck crosses several depth zones, so different routes reveal different sides of the site:

• Approximately 3–6 metres: The highest parts of the wreck and shallow structures, with plenty of natural light.

• Approximately 6–18 metres: The main recreational diving zone, featuring coral-covered beams, sections of the hull and abundant marine life.

• Approximately 18–30 metres: Deeper structures, the bow area and views of the wreck against the black-sand slope.

• Below 30 metres: Some surrounding areas may descend farther and are outside the limits of standard Open Water diving.

Exact depths and routes vary with the entry point, conditions and dive plan. Your guide will select the route according to your certification, experience, air consumption and the conditions on the day.

Can Open Water Divers Dive USAT Liberty?

Yes. Liberty is not reserved for advanced divers.

Open Water divers can normally explore its shallower exterior while remaining within the depth limit of their certification— 18 metres. This area already offers impressive views of the wreck’s scale, coral-covered metalwork, schooling fish and a wide variety of smaller marine species.

Its shallowest point does not, however, make every dive automatically easy. Tulamben is a shore-diving destination with a pebble and volcanic-rock entry. Waves can occasionally make entering and leaving the water more demanding. Divers should have reasonable buoyancy control, monitor their air carefully and follow the instructions of their local guide.

Non-certified guests may only visit an appropriate shallow area as part of a properly supervised introductory scuba programme, subject to local conditions and training-agency standards.

What Can Advanced Open Water Divers See?

Advanced Open Water divers with suitable deep-diving training can usually explore the deeper sections between approximately 18 and 30 metres, while staying within their personal training and certification limits.

Depending on the route, these areas may include:

• Broader views of the bow

• Boilers, beams and large structural sections

• Deeper sea fans and sponges

• Schools of fish moving through open sections

• Dramatic perspectives that are not visible from the shallow route

An Advanced Open Water certification does not automatically qualify a diver for wreck penetration. Entering an enclosed space introduces overhead, entanglement, silt and navigation hazards. It requires dedicated wreck training, appropriate equipment and a carefully prepared plan. Most recreational dives should remain outside the wreck or use only open areas with a clearly visible exit.

Dawn, Day or Night: Three Different Liberty Experiences

Liberty shipwreck changes dramatically throughout the day, and each time offers a different way to experience the wreck.

Dawn Diving

At dawn, the site is often quieter, with fewer people in the water. Soft early light gives the wreck a more atmospheric appearance and creates excellent opportunities to photograph silhouettes, light rays and schooling fish.

Day Diving

During the day, stronger sunlight brings more colour to the shallow wreck. Corals, sponges and smaller creatures are easier to observe, while the brighter conditions help first-time visitors understand the wreck’s layout. Daytime is also well suited to photographers who want to use natural light.

Night Diving at the Liberty

After sunset, the Liberty shipwreck becomes a completely different dive. A torch reveals one small section of the structure at a time while the rest of the wreck disappears into darkness, creating a quieter and more adventurous atmosphere.

One of the most exciting possible encounters is cooperative hunting between moray eels and giant groupers. Morays can search inside gaps in the wreck and between corals, while giant groupers wait outside for prey driven from its hiding place. Watching these very different predators work together can be one of the Liberty’s most memorable nighttime spectacles. As this is natural wildlife behaviour, sightings depend on the season, conditions and the animals’ activity and cannot be guaranteed on every dive.

Crustaceans and other nocturnal animals also emerge from their daytime shelters. Shrimp, crabs, nudibranchs and small reef fish may become highlights of the dive. Because attention is naturally focused on the area illuminated by the torch, divers often notice details that are easy to miss in daylight.

In short:

• Dawn: Quieter conditions, soft light and atmospheric wide-angle images.

• Day: Brighter colours and a clearer view of the wreck’s overall structure.

• Night: Nocturnal marine life, a unique atmosphere and excellent opportunities for detailed observation and macro photography.

The best time depends on the weather, visibility, entry conditions and the diver’s experience—not only the clock.

Safety and Certification Requirements

The Liberty is highly accessible, but it remains a genuine wreck in an open-water environment. A safe dive plan should include the following:

• Stay within the depth and conditions covered by your training.

• Dive with a buddy and an experienced local guide who knows the Liberty.

• Check waves, currents, visibility and shore-entry conditions before entering.

• Maintain neutral buoyancy and avoid touching the wreck or coral.

• Watch for sharp metal, fragile sections and possible entanglement hazards.

• Monitor depth, gas supply, no-decompression time and ascent rate.

• Never enter an enclosed section without the required training and plan.

• Complete a refresher before the dive if you have been out of the water for an extended period.

Open Water divers can enjoy the shallow exterior. Advanced or appropriately deep-trained divers can plan deeper routes. Any true penetration dive requires specialised wreck-diving training.

Night divers should also have reliable buoyancy, navigation and gas-management skills. Carry both a primary and backup light, and agree on entry points, buddy signals and lost-buddy procedures before entering the water. First-time night divers should receive appropriate training or complete the dive as part of a course conducted to recognised training standards.

Underwater Photography Tips

USAT Liberty is an excellent site for both wide-angle and macro photography.

For wide-angle images, include a diver to show the scale of the vessel. Dawn can produce silhouettes, beams of light and dramatic fish-school compositions, while daytime conditions are better for capturing colour on the coral-covered structure. Move close to your subject to reduce the amount of water between the camera and the wreck.

Macro photographers should inspect the edges of sponges, beams, corals and the transition between the wreck and black sand. Nudibranchs, shrimp, crabs and other small animals often hide in these areas. During a night dive, move slowly and avoid shining a strong light directly at an animal for an extended period.

If moray eels and giant groupers begin hunting, keep a respectful distance and never chase, surround or interfere with the animals or their prey. Prepare the camera settings in advance, use soft and controlled lighting, and allow the action to enter the frame naturally.

Practical photography tips:

• Choose a wide-angle or macro setup before the dive and plan the route around it.

• Use strobes or video lights to restore colour at depth.

• Use controlled fin movements to avoid disturbing the black sand.

• Never chase, surround or touch marine life.

• Do not rest a camera, pointer or any part of your body on the wreck or coral.

• Check buoyancy, depth and gas before concentrating on a photograph.

The golden rule is simple: complete a safe dive first and create a great image second.
