About this spot
Trawangan Dive Biorock sits in the Gili Islands marine protected area off North Lombok. The site is an active biorock installation—an artificial reef structure designed to accelerate coral growth through low-voltage electrical stimulation. Diving here puts you on the front lines of reef restoration, where you can observe both the technology and the marine life it attracts. The biorock itself draws juvenile fish, invertebrates, and small reef species drawn to the enhanced substrate. Because it's a restoration site, conditions vary with the restoration phase. The surrounding reefs within the protected area support the typical Coral Triangle biodiversity—triggerfish, groupers, snappers, and invertebrates are common sightings. Twelve documented species observations confirm active marine life use. Access is straightforward from Gili Trawangan's dive operators. The site sits within the Taman Wisata Perairan Gili Ayer, Gili Meno, Gili Trawangan marine park, so permits and local regulations apply. The islands themselves are accessible by fast boat from Lombok's mainland ports. Note: Current coral bleaching warnings affect the region. Water conditions and marine health vary seasonally. Check with local operators for real-time site conditions and visibility before booking.
