Pelong Rocks & Outer Reefs – Brunei Diving

About Pelong Rocks & Outer Reefs

Pelong Rocks and the outer reefs represent Brunei's premier natural reef diving, featuring isolated granite rock islets in the open South China Sea with crystal-clear visibility reaching 30 metres and dramatic underwater geological formations. Pelong Rocks offers schooling barracuda, big-eye trevally, leopard sharks resting on sand patches, and hard coral gardens thriving on the granite boulder formations. Nearby Cochrane Reef provides a natural coral bank with table corals, angelfish, butterflyfish, and occasional green turtles in a healthy patch reef environment far from the sediment-rich coast. These outer sites are the furthest offshore of Brunei's dive locations, requiring 40-45 minute boat transfers from Serasa, but reward with the best visibility and most pristine coral communities in the country. The granite rock formations create a striking contrast to the sand and wreck environments of the coastal sites, offering dramatic underwater landscapes, swim-throughs between boulders, and the sense of diving in a remote open-ocean environment. Pelong Rocks and Cochrane Reef are essential additions to any Brunei diving itinerary, providing the natural reef complement to the country's outstanding wreck and artificial reef sites.

Getting There

Pelong Rocks and the outer reefs are reached by boat from Serasa harbour, approximately 40-45 minutes offshore in the open South China Sea. The longer crossing requires calm sea conditions and is conducted during the dry season from March to September. Some operators combine Pelong Rocks with the nearby Blue Water Wreck for a full offshore diving day. Weather-dependent scheduling is essential with flexible backup dates recommended.
