Dive-site story
Located in Gilimanuk on the northwest tip of Bali, Secret Bay is a premier muck diving destination consisting of a shallow coastal inlet. The substrate is largely fine grey and black volcanic sand mixed with patches of rubble, discarded debris, and sparse seagrass beds. Photographers flock here specifically for macro oddities that thrive in quiet, sheltered estuarine environments, with high-tide windows offering the clearest conditions.
