Mnemba Atoll is the most popular dive site of Zanzibar where there is a great variety of marine life, including a resident pod of dolphins! Meeting time is in the morning (between 8:00 a.m. and 11:00 a.m.) and we are back after 5-6 hours (between 1:30 p.m. and 3:30 p.m.), depending on the tide and sea conditions.
