While Bali offers great diversity of dive sites, Gilimanuk Bay (or Secret Bay as it is known locally) is unique within Bali. It is the very definition of muck-diving. No rich coral reefs, no depth to speak of, it is basically a site for macro-photographers and for the occasional recreational diver looking for something different from the norm.

Secret Bay contains many rare macro-photography subjects that include nudibranches, dragonets (including both the colorful Mandarinfish and Picture Dragonet), abundant seahorse/pipefish, unusual scorpionfish, frogfish, eels, and many, many other organisms.
