The Abyss is a dramatic wall dive off a jungle-fringed shore in the Togeans, with a steep drop-off, massive sea fans, and a small cave feature partway down the wall. The reef is heavily covered in life, with soft and hard corals, reef fish, and plenty of small critters, making it one of the standout dives around Una Una. It suits divers who enjoy a relaxed boat entry, mild current, and a classic wall profile with strong visual relief.
