Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Tulamben offers divers a rich underwater world, anchored by the iconic USAT Liberty wreck. Sunk by a Japanese torpedo in 1942, this cargo ship initially grounded on Bali's shore for decades.
A powerful 1963 earthquake later shifted it off the beach, causing it to settle on its side in deeper water. The wreck now spans approximately 5 m / 16 ft to 30 m / 100 ft, its entire structure heavily colonized by corals, creating a vast artificial reef. Beyond the Liberty, Tulamben's diving landscape includes sites like Gerombong, Batu Niti, and Batu Ringgit.
These spots, often accessible via shore entries, unveil diverse underwater terrains: sandy slopes, lively coral gardens, and intriguing volcanic rock formations. Dives frequently commence with a simple walk into the water, easing access for both novice and seasoned divers.
A blend of historical significance and varied reef environments ensures a comprehensive diving experience.

Best Time to Dive
Diving in Tulamben benefits from seasonal planning, though favorable conditions exist year-round. Air temperatures consistently measure 26-29°C / 79-84°F, ensuring comfortable surface intervals. While rated "Good" all months, the dry season (April to October) typically experiences minimal rainfall, often less than five millimeters monthly. Calmer sea conditions generally prevail during this period, with average wave heights typically staying below one meter, particularly from April to June and October to December. Wind speeds are also usually lower outside the July-September period, when averages can reach nearly nineteen kilometers per hour. For avoiding crowds at the Liberty wreck, consider early morning sunrise dives or late afternoon excursions. Such timings frequently provide a more serene atmosphere and excellent light for photography.

Dive Experience & Conditions
Underwater conditions in Tulamben typically feature calm and manageable characteristics, suitable for divers of varying skill levels. Mild surface currents are common, yet can fluctuate with tidal shifts and seasonal influences. Water temperature is not consistently reported, but often registers between 27-29°C / 81-84°F in the area. Most dive sites, major attractions included, involve shore entries; divers walk directly from the beach into the water. Convenient access supports a relaxed diving pace.

Around the USAT Liberty wreck, its sheer size and coral growth offer ample shelter for marine life. Gerombong, for example, is noted for its straightforward navigation, while Batu Ringgit presents a more complex layout for detailed exploration.
Dive Difficulty & Safety Guidelines
Adhering to safety guidelines in Tulamben is crucial for all divers, from beginners to advanced enthusiasts. Employing local dive guides comes highly recommended; they offer insights into marine life and site-specific nuances. Many sites are simple shore dives, but excellent buoyancy control remains essential, particularly around the delicate corals of the Liberty wreck and in busy macro environments. Watch for potential boat traffic during ascents, as local fishing activity occurs in some areas. Always follow core safe diving practices: respect depth limits, manage air consumption, and never touch marine life or damage corals. Such measures protect both personal safety and Tulamben's fragile underwater ecosystems.
