It was in 1978 that Menjangan became Bali's first internationally-known dive location. Consequently, in older dive guidebooks, Menjangan is described as having beautiful reef flats. Unfortunately that is no longer true. On a more positive note, Menjangan is actually famous for the wall-diving.

The walls descend to varying depths, the shallowest being 26m, the deepest 60m+. The walls offer the greatest diversity of gorgonian fans in Bali. They generally start at 10m with the flat coral reefs offering gentle conditions and lots of sunlight. These are full of medium and small fish. The walls are full of small nooks and crannies, overhangs, and bigger cavelettes, crevasses, etc. They are covered with soft corals, gorgonian fans, sponges.
