Batu Bolong Dive Site

Batu Bolong is a small pinnacle that rises from deep water, creating a unique underwater mountain covered in an extraordinary density of soft corals, sea fans, and marine life. The nutrient-rich currents that sweep past the rock attract everything from tiny nudibranchs to reef sharks, making it the single most biodiverse dive in Komodo National Park.

We recommend at least Advanced Open Water certification and some drift diving experience. The currents at Batu Bolong can change quickly, and divers need to be comfortable managing buoyancy near a reef wall. Our dive guides always brief the conditions thoroughly and time every dive to match the tidal window.

Batu Bolong is diveable year-round, but April through November offers the best visibility (up to 30 meters) and calmer surface conditions. Even during the wet season, the site remains spectacular since the currents that reduce visibility also bring in more pelagic action.

The pinnacle starts at about 5 meters below the surface and drops steeply to beyond 40 meters. Most dives stay between 10 and 25 meters where the coral coverage and fish density are at their peak. Your dive guide will plan the depth based on group experience and current conditions.

Yes, white-tip reef sharks are common residents around the deeper sections of the pinnacle. Grey reef sharks also visit regularly, especially when the current is running. They are not aggressive toward divers and can often be observed resting on ledges or cruising along the wall.

Batu Bolong is approximately 45 minutes by boat from our resort on Sebayur Island. We run daily dive trips to this site when conditions are favorable. It is also a regular stop on our Komodo Sea Dragon and King Neptune liveaboard itineraries.
