Menjangan Island is a 30 minute boat ride from the harbor near Pemuteran. The island is small and not the destination itself, rather the waters and reefs surrounding the island are the attraction, offering some of the best snorkeling and diving in Bali.
There is a well marked snorkeling trail off the shore, providing an easy to follow path along the edge of the many corals growing close to the shore. The reefs provide a vital aqua-culture sustaining a wide variety of sea life. Hard corals, soft corals, clown fish, blue starfish, cuttlefish, barracuda and a wide variety of beautiful fish are commonly seen.
Pemuteran provides the best jumping off point with a variety of accomodations available and tour operators who can arrange to get you to Menjangan. Shop around as prices vary. Many will pack a box lunch for you to enjoy on the small beach on the island. Make sure you check for safety equipment on the boats yourself before leaving harbor. Seas can be choppy in January and February, with poorer visibility. Get an early start and avoid both problems.
