Zanzibar's most interesting areas for diving are to be found in the north of the island. However, if you'd like to swim with dolphins, they usually bask in the waters to the south. But before you put on your equipment, don't forget that the island of Zanzibar is subject to strong tides. This phenomenon has a huge impact on outings, since the sea displaces the marine deposit and can therefore greatly alter visibility, making diving complicated and even unpleasant.
