Quick Answer: Batu Bolong is Komodo’s most iconic dive site—a dramatic underwater pinnacle rising from 40+ meters, home to reef sharks, napoleon wrasse, giant trevally, and sea turtles. Strong currents make it best suited to intermediate-to-advanced divers, ideally dived during the dry season (April–December).
Batu Bolong sits within Komodo National Park, its name meaning “rock with a hole” in Indonesian—a reference to the underwater pinnacle that defines the site.
The pinnacle rises from roughly 40 meters at its base to within 8 meters of the surface, with a natural tunnel-like passage at about 12 meters that gives the site its name.
Strong, current-focusing conditions concentrate nutrients and pelagic life here, making it Komodo’s most photographed and requested dive.
From its dramatic pinnacle to its resident sharks, four elements define every dive here.
The primary pinnacle spans roughly 40 meters at its base to 8 meters near the surface, with a natural tunnel at 12 meters that gathers schooling fish and hunting predators. Most recreational dives run 12–35 meters, within a 40-45 meter safety limit.

Grey and blacktip reef sharks patrol the pinnacle alongside napoleon wrasse, schooling giant trevally, and hawksbill and green turtles. Manta rays and whale sharks make seasonal appearances too.
View Marine Life GuideCurrents typically run 1.5–2.5 knots, reaching 3+ knots on spring tides—strong enough to reward divers who position across the flow rather than fight it. Visibility exceeds 25 meters in the dry season, with water at a comfortable 27–29°C.
Explore Liveaboard OptionsDramatic pinnacle topography and constant pelagic action make Batu Bolong a wide-angle photographer’s favorite, especially in the dry season’s clearer, brighter water. Strong currents call for solid buoyancy control to keep both camera and composition steady.
Book Your Dive
Batu Bolong is best experienced by liveaboard, which allows early-morning dives, multiple return visits across a week, and the flexibility to wait out weaker conditions before returning when currents and light are right.
It pairs naturally with nearby Castle Rock and Crystal Rock—three sites often combined across a single liveaboard week to showcase Komodo’s range of current-driven diving. Day trips from Flores reach it too, just in a narrower window of conditions.
Advanced Open Water certification or equivalent experience is recommended, given the strong currents and deep pinnacle structure. Rescue Diver or Divemaster-level training is better suited for optimal safety and enjoyment.
Currents typically run 1.5–2.5 knots, with 3+ knots possible during spring tides. Guides position divers to use the current to their advantage rather than fight it.
Expect grey and blacktip reef sharks, napoleon wrasse, large schools of giant trevally, groupers, snappers, and hawksbill and green turtles. Manta rays and whale sharks appear seasonally, though sightings are never guaranteed.
The dry season (April–December) is prime, with April-June and September-November offering the most consistent conditions and 25-40+ meter visibility. Batu Bolong can be dived year-round, though the wet season (January-March) brings less predictable weather.
Yes, typically requiring 45-90 minutes of boat travel. A liveaboard unlocks the site’s full potential though, with multiple dives and overnight positioning for the best light and conditions.
The pinnacle descends from about 8 meters at its shallowest to 40+ meters at its deepest, with the distinctive tunnel at roughly 12 meters. Most dives operate between 12-35 meters, and your guide sets exact depth parameters during the briefing.
Recreational dives last 45-55 minutes on average. The strong current increases air consumption somewhat, so guides monitor supplies closely and build in safety margins for ascent.
Yes—it’s exceptional for wide-angle photography, pairing dramatic pinnacle topography with abundant pelagic action. The dry season’s clearer water and better light enhance color, though photographers need solid buoyancy skills to manage the current and their gear together.
