Secret Bay is the more poetic name given by Bali’s diving community to Gilimanuk Bay, located in West Bali National Park, about 20 minutes by road from Labuan Lalang/ Menjangan or 3 hours ride from Sanur. This Bali dive site offers muck-diving in shallow water with no current, so suitable for all level of divers. Visibility is average 3-15 meters with the sand and some debris. Due to strong tidal currents mean that the fish and invertebrates are extremely healthy, colourful and well-fed. It is also colder than generally found in Bali, around 25oC so wear a good wetsuit.
The bay is about 2 km wide, 3-12 meters depth. The best time to dive is on the incoming tide or around high tide, it doesn’t matter if it’s early or late in the day, as the bay will have filled with clear water from the Bali Strait. You can expect to see Mandarinfish, nudibranches, gobies, crustaceans, dragonets, abundant seahorse/pipefish, juvenile Batavia batfish, large areas of long-spined sea urchins with clingfish, and many, many other creatures.
Slowly work on the garbage and most probably there is something underneath. Snake Eels , Sea Snakes, Cockatoo Fish, Juvenile Rabbit Fishes, Flounders, varieties of Gobies, Frog Fishes, Dragonets, Nudibranch, Sea Hares and many more. If you are an Underwater Photographer or Video shooter , you may spend 2 hours bottom time, 3 to 4 dives a day and still find something new.
