Located five miles (8 km) northwest of Bali within West Bali National Park, the small island of Menjangan offers some of the best scuba diving in the Bali area thanks to its pristine coral reefs, deep drop offs and various caves. Dive operators in Bali make day trips to the island to spot groupers, moray eels, batfish, snapper, barrel sponges and enormous sea fans among others.
Some of the island’s most notable dive sites include Anchor wreck (the site of a sunken Dutch slave ship), Eel Gardens (home to a large colony of garden eels) and Secret Bay, a unique underwater habitat popular among underwater photographers for its colorful collection of sea horses, nudibranches, lionfish and ribbon eels. The island is also home to many deer ("Menjangan" is the Javanese word for "deer").
Diving conditions around Menjangan Island are best from April to November. The snorkeling is also topnotch, with calm, clear waters and plenty to see just beneath the surface.
