Secret Bay is the name given by divers to Gilimanuk Bay in west Bali. The Bay is part of the Bali Barat Nasional Park and is shallow with a muddy bottom. The reason for diving in Secret Bay is the extraordinary marine life including nudibranches, gobies, crustaceans, dragonets, seahorses, pipefish, juvenile batfish, long-spines sea urchins, clingfish and many more. The muddy bottom means divers have to be careful not to stir things up. Larger fish tend not to dwell in Secret Bay but the advantage of that is the smaller ones do not have to hide.
Night dives include sights of octopus, squid and cuttlefish. The man draw of Secret Bay is that is offers a different diving environment to the other locations on the island. There is no reef, its shallow and full of macro-photography subjects.
Divers at Pemuteran around to the NE might enjoy a days diving at Secret Bay. From Kuta you head west towards Tabanan. Gilimanuk Bay will be approximately 3 hours. Be sure to go with a reputable company like Scuba Duba Doo in Kuta.
