Secret Bay

Secret Bay in Gilimanuk is one of the world's most renowned muck diving sites, a shallow sheltered bay on Bali's northwestern tip where extraordinary critter diversity belies the unassuming setting. The sandy and silty bottom between 2 and 12 meters depth hosts an incredible array of rare species: Banggai cardinalfish (an introduced colony far from their native Sulawesi), robust and ornate ghost pipefish, dragonets, Ambon scorpionfish, and multiple species of seahorse and pipefish. Bobbit worms lie in ambush, coconut octopus hide in shells, and frogfish blend seamlessly into sponges. Night dives are legendary, revealing Spanish dancers, bobtail squid, and stargazers. The combination of incredible biodiversity, easy diving conditions, and shore access makes Secret Bay a world-class destination for macro photography and critter enthusiasts.
