This is one of our most recommended activities to do in Zanzibar. Mnemba Island reef is one of the best reefs in East Africa, where you spot different species of fishes. This trip includes Dolphin Tour, Snorkeling at Mnemba Island reef, and Sandbank if it will be available. (it will not be possible to see a sandbank when it is high tide as it will be fully covered).Snorkeling at Mnemba reef is a lifetime experience that you will not want to miss.
