Gili Biaha
Candidasa · Indonesia
Gili Biaha is a small uninhabited island north of Candidasa known for its underwater cave and resident population of white-tip reef sharks. The cave entrance at around 15 metres leads into a shallow cavern where sharks rest during the day — one of the few accessible shark cave experiences in Bali. Outside the cave, walls drop to 30 metres with healthy hard coral and abundant reef fish. Strong currents are common so timing and briefing are essential.
