Dive Spot Guide•
Bio Rock
Shallow Gili Trawangan BioRock reef-restoration dive with easy access.
Usually dived as a relaxed east-coast site near Gili Trawangan, where the restored structures keep the route simple and make it practical for gentle scuba dives and shallow exploration.
About Bio Rock
Bio Rock is a shallow Gili Trawangan reef-restoration site built around electrified metal structures that encourage coral growth. Divers visit it less for dramatic topography than for the artificial reef framework itself, which draws reef fish, small predators, turtles, and other marine life around a site that is easy to combine with relaxed island diving.
