What is the Dolphin Tour?
Kizimkazi, a small fishing village on the southern tip of Zanzibar, is home to two resident species of dolphin: the Indo-Pacific bottlenose dolphin and the humpback dolphin. These pods live in the shallow coastal waters year-round, which has made Kizimkazi the most accessible location in Zanzibar for dolphin-watching trips. The tours are among the island's most booked excursions.
Trips depart early in the morning by small motorboat, when the sea is calmer and dolphin activity is at its highest.
What to Expect
Boats leave Kizimkazi Dimbani harbour shortly after sunrise. Local fishermen who run the tours have years of experience reading the water and tracking pod movements — they often spot dolphins within 20 to 40 minutes of departure. Both bottlenose and humpback dolphins in this area are accustomed to boat presence, and it is common to see them swimming alongside the hull or surfacing nearby.
Most operators offer the option to enter the water when a pod is located. In practice, the dolphins rarely stay in one place long enough for sustained swimming, but snorkellers do occasionally find themselves briefly surrounded by a passing group. Humpback dolphins tend to be shyer and less likely to approach.
The journey to and from the dolphin grounds passes over shallow reef, so some operators combine the trip with reef snorkelling either before or after the dolphin search.
Good to Know
The ethical dimension of these tours deserves serious attention. During peak season, dozens of boats can converge on a single pod simultaneously. Research on East African coastal dolphins has documented stress-related behaviour changes in areas with heavy boat traffic. When booking, ask whether the operator limits the number of boats per pod, avoids using engines near animals, and instructs passengers not to chase or corner dolphins. Choosing a conscientious operator makes a difference. Bring a waterproof bag for your phone or camera and expect a wet ride on open water. Kizimkazi is about 50 kilometres from Stone Town — most visitors combine it with Safari Blue or a visit to the village's ancient Shirazi mosque.
