Jozani Forest is the largest area of indigenous forest on Zanzibar Island. Situated south of Chwaka Bay on low-lying land, the area is prone to flooding, which nurtures a lush, swamplike environment of moisture-loving trees and ferns. The whole area is protected as Jozani-Chwaka National Park (🎟️12 USD), the only national park in Zanzibar. It is famously home to populations of Zanzibar red colobus monkey (an endangered species found only on Zanzibar) as well as other monkey species, bushbabies, duikers and more than 40 species of birds. At the park headquarters, there’s an information centre, and the main activity is following the forest nature trail (it takes about 45 minutes to walk). Nearby is a boardwalk through the creek-side mangroves.
