The Jozani Chwaka Bay National Park is a 50 km2 (19 sq mi) national park in Tanzania located on the island of Zanzibar. It is the only national park in Zanzibar. The Zanzibar red colobus monkey can be found in the park, as a rainforest species (unlike the black-and-white colobus found in other regions of Africa). Other species of fauna found in the park are the Zanzibar leopard (which is extremely elusive to the point they were believed to be extinct), the Sykes monkey, bush babies, more than 50 species of butterflies, and 40 species of birds.
The island was used as a prison for rebellious slaves in the 1860s and also functioned as a coral mine. There are 15 holiday cottages in the northwest of the island as well as a tennis court, swimming pool, and library and the old European Bungalow has been turned into a restaurant named after Mathews. The old prison remains standing, providing shelter for some of the giant tortoises found on the island and the cells can be visited.
Mangapwani is a town on the Tanzanian island of Unguja, the main island of Zanzibar. It is located on the northwest coast, 25 kilometers (16 miles) north of the Zanzibari capital of Stone Town. The shoreline here contains numerous caves, some of which were used for holding slaves during the black-market slave trade of the 1840s. Among the caves is a popular attraction, the Coral Cavern, which is located two kilometers south of the town.
