Site details

A striking wall dive off Ternate island where large underwater crevices form a sizeable arch at roughly 20 to 30 m. Coral cover is very healthy with whip corals and gorgonians, and the long whip corals can host rare wire-coral shrimp. Impressive topography of walls, arches and overhangs makes it one of the most dramatic dives in the Alor area.
