Biorocks is a shallow east-Gili Trawangan house-reef style dive where restoration frames sit on a gently sloping bottom and attract small marine life. It is better known as a patient macro and muck-style site than as a dramatic reef, with rays, seahorses, pipefish, and other critters giving the area its appeal.

Scuba Diving
Good muck-diving on a gentle slope with artificial reef structures to explore.
Freediving
Public site guides reviewed for Biorocks emphasized scuba access and shallow muck-style exploration more than structured freedive use.
Snorkeling
Because the restoration frames sit in shallow water, Biorocks can also appeal to confident snorkelers when conditions are calm and a local operator confirms access.
