Site details

A spectacular site between Pura and Alor where a steep above-water cliff continues underwater as jumbled boulders and a coral-clad wall of hard and soft corals and sponges. A swim-through with a cave at around 25 m can shelter resting tawny nurse sharks, while the reef holds pygmy and Pontohi seahorses, frogfish and blue-ringed octopus. Dramatic topography makes it an Alor favourite.
