The most popular dolphin spotting location in Zanzibar is in Kizimkazi village located on the Southern coast of Zanzibar Island where you can see both bottle-nose and humpback dolphins.
The shallow coastal waters around Kizimkazi are a favorite hangout for dolphins that come here for the reliable food supply, to nurse their calves, rest and socialize.
Several bottle-nose dolphins stay at Kizimkazi all year-round. There are also rather shyer humpback dolphins that put in an appearance here, although their schedule is a little more erratic.
Dolphin tour is best very early in the morning, because in the afternoon as the sun rises sea water tends to become warm, therefore dolphins dive deep down the sea bottom to escape heat.
