Main image

Tumbatu is a small inhabited island off the northwest coast of Unguja (Zanzibar), within Tanzania’s Zanzibar archipelago and administratively part of Unguja North Region. The island is separated from Unguja by a narrow channel and is home to local fishing communities.

The island has few tourist facilities and is principally visited for its local culture, fishing villages and quiet coastal scenery; most visitors arrive by small boat for day trips rather than overnight resort stays. Commercial development is limited compared with Zanzibar’s main tourist hubs.

Tumbatu sits off Unguja’s northwest shore in the Zanzibar archipelago in the Indian Ocean. Access is by local boat services from the main island; the island’s shoreline is low-lying with mangrove and reef in places.

  • Access and facilities: Ferry access is by small local boats rather than large car ferries, and facilities on the island are limited so visitors should bring supplies for day trips.
  • Local character: The island is inhabited and retains traditional local lifestyles, making it of interest for cultural day visits rather than resort-style tourism.
