Tulamben has become Bali's most famous diving area. Tulamben Bay, like the rest of Bali, is situated in the richest marine biogeographic zone in the world. Being on the northeast coast, the bay receives plankton rich waters from the major ocean currents that move from the Pacific to the Indian Ocean. This, coupled with the fact that the three main dive sites provide totally different physical environments, means that Tulamben contains a stunningly diverse underwater ecosystem.
