Boat-only manta cleaning-station reef off south Nusa Penida.
Boat-only manta cleaning-station reef off south Nusa Penida.
Boat-only site; local guide support is the normal way to manage current, pickup timing, and snorkel windows.
Batu Lumbung (Manta Point) is a boat-only south Nusa Penida manta site built around an exposed limestone-and-sand cleaning-station reef. Divers come for regular reef-manta encounters and the chance to watch them circle the boulders, not for colorful coral. Treat it as a weather-sensitive open-ocean outing: current, surge, and boat timing matter more than depth.
Conservative baseline from public research. No community dives logged yet.
Depth range, seasonality, and planning context.
Reported Depth
8m - 25m
Depth Note
Cleaning stations sit around 8 m, and the site is commonly run across a 5-25 m band over the rocky slope.
Best Season
Year-round for mantas; April to October usually gives the calmest windows.
Typical Conditions
Visibility is usually 10-20 m, with current and surge varying by sea state.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Use an experienced local guide, keep the group tight, and treat calm-weather windows as the green light for snorkeling. The site can tighten fast when swell or current builds.
Access Restrictions
Boat access only. Snorkeling should be limited to calm-weather windows with direct in-water supervision; the site may be skipped when swell or current build.
Legal Notes
Follow licensed-operator briefings and any marine-park or weather closures before entering the water.
Community notes to help plan your visit.
Scuba Diving
Best as a guided boat dive on the cleaning station and surrounding rocky slope.
Freediving
Not a primary freedive stop; keep to calm-water, guide-led windows if you attempt it.
Snorkeling
Only in calm conditions, and best for experienced snorkelers with a dedicated in-water guide and life-jacket support.
