Travelling to Bali promises many joys, but Bali's dive sites are in a class of their own and constitute one of the main reasons this island is endlessly popular. With deep drop-offs, steep banks, coral ridges and a world famous wreck, these waters are home to a great wealth of ecological, geological and historic sights, framed by a coast dotted with volcanoes and rice paddies. The most popular dive destinations are Nusa Penida, Tulamben, Amuk Bay and Menjangan. The famous wreck is that of the USAT Liberty, which is one of the world's most celebrated wreck dives, located just outside of the village of Tulamben.
Some of the extraordinary local marine life that you can see in Indonesia includes mola mola (sunfish), hairy frogfish and pygmy seahorses, while more 'usual' sightings include reef sharks, blue spotted stingrays, turtles and parrotfish. Visibility can be anywhere between six and 45 metres, and current strengths also vary substantially from one dive site to another. The water is generally at a comfortable temperature and the best diving months are from April to December.
There are various locally based dive operators and resorts offering everything from beginner snorkelling to dive excursions or full scuba diving courses. Visitors may use their own kit or rent equipment from the operator or resort. All divers must carry valid scuba certification. For those interested in underwater photography the dive centre in Tulamben hosts courses.
