Drop Off is a wall and cave dive site in Malaysia, in the Celebes Sea, within Sipadan Island Park. The site begins with a 9.14 metre walk on the beach before the wall drops to about 600 metres. Divers reach it by boat, to a maximum depth of 22 metres. It is rated for advanced divers, with an overhead environment. Divers must be accompanied by a local dive master to enter the interconnecting caverns. Sipadan Island Park requires a permit to dive, issued under a daily quota. Grey reef sharks, whitetip reef sharks, big reef fish and schooling fish are resident, and turtles are occasionally seen.
