The sun is low over Bali’s eastern shore as you kit up on a black-sand beach; the sea ahead quietly keeps its secrets. From the surface the Liberty’s rusty hull looks placid, but once you descend the wreck’s angles and the Drop-Off’s vertical wall press the ocean into a close, moving world that tests planning, buoyancy, and nerves.

The sun is low over Bali’s eastern shore as you kit up on a black-sand beach; the sea ahead quietly keeps its secrets. From the surface the Liberty’s rusty hull looks placid, but once you descend the wreck’s angles and the Drop-Off’s vertical wall press the ocean into a close, moving world that tests planning, buoyancy, and nerves.
Tulamben’s underwater story is as layered as its shoreline: the USAT Liberty was torpedoed in 1942 and now forms one of Southeast Asia’s most accessible wreck habitats, while the Boga—a patrol ship—lies deeper, its structure colonized by corals and schooling jacks. Geologically, dives here are framed by volcanic slopes fed from nearby Mount Agung; currents can funnel nutrients, feeding dense life on artificial and natural reefs alike. The area is served by small dive communities—local boat operators and family-run resorts that mix Indonesian fishing culture with SSI training standards.
Practically, expect a focused two-day course that blends classroom briefings with three supervised open-water dives, including a 40m deep dive. Nitrox training increases allowable bottom time but brings extra gas-planning discipline; you’ll practice mixes, planning, and staged ascents. Bring a calibrated dive computer, know your limits, and be ready to manage longer surface intervals. Hydrate, sleep well the night before, and avoid flying for 24 hours after your last dives. Groups are intentionally small for personalized instruction, so this combo is ideal for certified divers wanting to move confidently into deep and wreck environments.
challenging.
2 days.
Moderate to fit—comfortable swimming ability, good cardiovascular health, and no recent respiratory or ear issues.
Yes—participants must hold an Open Water Diver certification before enrolling; instructors will verify credentials at check-in.
Training includes dives down to approximately 40 meters (130 feet) under direct supervision and with gas planning tailored to Nitrox use.
The program is designed across two days, combining classroom/briefings, surface planning, and three supervised open-water dives.
Nitrox can extend bottom time and reduce nitrogen uptake at shallower depths but requires strict PO2 management—safety depends on correct gas planning and monitoring.
Ocean Sun Dive Center operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
