Nusa Penida -- This island is the nearest dive site for those staying in the south of the island. It is a 40-minute boat ride from Sanur and benefits from the main deep water channel current running down the Lombok Strait. The main draw is from July to November when there is a high chance of swimming with the large Mola-Mola, or oceanic sunfish, or around the same time, you may find manta rays.
Bloo Lagoon -- This small, white-sand bay just outside Padangbai is not normally a recipe for finding interesting fish, but the treasure-trove of marine life here includes sharks, stonefish, scorpionfish, and nudibranches. One of the highlights of this dive spot is its night dives.
Gili Biaha -- This island is a 25-minute boat ride north of Candidasa and has some of Bali's most stunning diving. Here you will find a vast diversity of fish, sharks, and frequent pelagic visitors set against a backdrop of chiseled black walls with beautiful, healthy corals and often superb visibility. Go to the Shark Cove and you are almost guaranteed to see a white tip shark or two.
USAT Liberty -- Certainly the most famous and most popular dive site in Bali, this wreck lies between 3m and 37m (10 ft. -- 120 ft.) from the surface and can be enjoyed by serious divers and snorkelers alike. It is easy to reach from the shore and hosts over 300 species of fish. Go for a night dive.
Menjangan Island -- Situated in the West Bali National Park, 10km (6 miles) offshore, this deer-inhabited island offers deep coral reef walls only 45m to 90m (150 -- 300 ft.) from shore, with a diversity of gorgonian fans and plenty of small and medium-size fish on view. The protected island is reached by boats staffed by ex-fishermen from the area. The high visibility coupled with the gentle currents make this an exceptional place for the whole family.
Belongas Bay -- This bay in south Lombok has many excellent dive sites and pristine and as yet unpolluted reefs. There is plentiful macro life and an abundance of mackerel, tuna, barracuda, napoleon wrasse, and white and black tip reef sharks. You may even get to see hammerhead sharks.
The Gili Islands -- Located off the west coast of Lombok, and with over 20 accepted sites, this is an ideal location to base yourself if you want to spend the day sub aqua. The Gilis are famous for their turtles and if you are quick and fortunate, you may even get to swim with them.
