It is the largest area (10 km2) that remains of the endemic alluvial forest that once covered almost the whole island before it was subjected to reclamation and crops; it constitutes a rich set of different natural habitats of the island; entering inside, between lianas and imposing trees of ficus and red mahogany, exotic birds, antelopes, vervets, reptiles and mangroves whose view really takes your breath away, you will find yourself surrounded by Colobus monkeys: characterized by a red cloak and a character tame, they are exclusive to Zanzibar; to preserve their existence and the balance of this fragile ecosystem, since 1995 Jozani has become a protected area.
