Mnazi Bay-Ruvuma Estuary Marine Park is a vast coastal and marine protected area in southern Tanzania, offering diverse coral reefs, mangrove forests, and rich marine biodiversity, ideal for snorkeling, diving, and eco-tourism.
Mnazi Bay-Ruvuma Estuary Marine Park is located along Tanzania’s southern coastline, near the border with Mozambique in the Mtwara Region. Covering approximately 650 square kilometers, this marine park protects critical habitats including coral reefs, seagrass beds, and expansive mangrove forests. The park encompasses the Mnazi Bay and the Ruvuma River estuary, creating an ecologically rich transition zone between freshwater and marine environments. Historically, local fishing communities have depended on these waters for sustenance. The establishment of the park in 2000 aimed to preserve fragile ecosystems while promoting sustainable tourism and fisheries management. Visitors can explore thriving coral gardens teeming with tropical fish, marine turtles, and dugongs, one of the few places in East Africa where these elusive mammals are regularly sighted. The mangrove forests serve as nurseries for important fish and crustacean species and help protect coastal areas from erosion. Key recreational activities include snorkeling over vibrant reefs, birdwatching along the estuary, and boat tours highlighting the park’s natural beauty and cultural heritage of the Mwani and Makonde peoples. While the park is relatively remote, it attracts eco-tourists and conservationists seeking off-the-beaten-path marine experiences and opportunities to support community-led environmental stewardship. Responsible visitation and local guides enhance the appreciation of this unique ecosystem, which is crucial for marine biodiversity in the Western Indian Ocean. The park’s ongoing conservation efforts address threats from overfishing, habitat degradation, and climate change impacts such as coral bleaching.
