About this spot
The Cleavage is a dive site located near Genteng Besar Island in the Thousand Islands Regency, Jakarta Province. This spot draws divers seeking access to the unique geology and marine life of Indonesia's island chain. The site sits outside a marine protected area, giving it a different character than some neighboring destinations. Divers at The Cleavage can expect encounters with diverse marine species documented through local observations. The community has logged multiple video records from the site, creating a growing library of reference material for dive planning. Year-round access makes this a flexible choice for travelers with variable schedules. Coral health in this region warrants attention.
