Dar es Salaam Marine Reserve, Marine reserve of nine uninhabited islands in Dar es Salaam Region, Tanzania

The Dar es Salaam Marine Reserve System comprises nine uninhabited islands in the Indian Ocean off Dar es Salaam: Bongoyo, Mbudya, Pangavini and Fungu Yasini north of the city, and Makatumbi, Kimbubu, Sinda and Kendwa to the south. It protects coral reefs, mangroves and seagrass beds, and is managed by Tanzania's Marine Parks and Reserves board.

Marine protection began in 1970 with the Fisheries Act and became more formal through the 1998 Marine Parks and Reserves Act. These laws established the framework for safeguarding coastal ecosystems.

Fishermen from Kunduchi, Ununio and Msasani depend on the reserve's fish, and local fishermen link falling catches to small-mesh nets and dynamite fishing. Bongoyo and Mbudya are the islands most visited, by foreign tourists and Tanzanian residents alike, for swimming, sunbathing, coral viewing and walking.

Regular boat services from Msasani Peninsula provide access to the islands, especially to popular destinations like Bongoyo Island. Crossings work with different time schedules, allowing visitors to explore individual islands.

Bongoyo Island harbors some of Tanzania's largest coconut crabs in their natural habitats. These unusual crustaceans often surprise visitors and demonstrate the reserve's ecological distinctiveness.
