Ilha do Bazaruto (island of the mist) is a sandy island located approximately 80 kilometres southeast of the mouth of the Save River, Mozambique. It is the largest island in the Bazaruto Archipelago and in the Bazaruto National Park. Because the water along this coastal area is very clear, much of the sub-surface channel pattern around the island is discernible. Bazurato Archipelago holds the largest population of dugong in Mozambique (around 300 animals) and almost certainly is the last remaining viable population of dugongs left off East Africa. The closest mainland town to the island of Bazaruto is Inhassoro, although administratively it belongs to the Vilankulo District and Inhambane Province.
