Tulamben has become Bali's most famous diving area and therefore where you are most likely to meet internationally recognised underwater photographers and writers. Tulamben Bay, like the rest of Bali, is situated in the richest marine biogeographic zone in the world. Being on the north-east coast, the bay receives very plankton-rich waters from the major ocean current that moves from the Pacific to the Indian Ocean. This, coupled with the fact that the three main dive sites provide totally different physical environments, mean that Tulamben contains a stunningly diverse underwater ecosystem.
The beach is fist-sized black volcanic rocks that become sand in the shallows. This black sand does not provide the reflective properties of white limestone sand and, combined with the amount of plankton in the water, accounts for the relatively low visibility (12-25M). It does however provide a dramatic contrast, which brings out the colours of the corals, gorgonians, fish and other marinelife. The 100s of macro-species that live here both blend and contrast beautifully with the sand.
