Zanzibar's Jozani Forest: A Time to Meet the Island's Only Red Monkeys
In the southeastern part of Zanzibar Island, Tanzania, lies the island's only national park. Designated in 2004, Jozani Chwaka Bay National Park covers approximately 50 km² and is a unique ecosystem where groundwater forest, coastal forest, mangrove forest, and salt marshes all come together in one place. According to the English Wikipedia, this is the largest remaining natural forest in Zanzibar, and in 2016, a broader area including the surrounding region was designated as a UNESCO Biosphere Reserve. The star that makes this forest special is the Zanzibar red colobus (scientific name Piliocolobus kirkii). This endangered monkey is found only in Zanzibar in the entire world, and Wikipedia estimates this population at around 1,000 individuals, noting that it has been established as the island's flagship conservation species since the mid-1990s. The UNESCO Biosphere Reserve introduction page also states that this area is an important biodiversity hub as the habitat of endemic species such as the endangered red colobus, Aders' duiker, and the Jozani frog (Kassina jozani). The park is divided into the forest area and Chwaka Bay on the sea side. Chwaka Bay, where seagrass beds and mangrove forests are intertwined, serves as an important breeding ground for fish and birds, and is an area for which Ramsar Wetland and World Heritage listing is being pursued. In the forest area, you can closely observe colobus troops moving among the branches on guided walking trails, and in the mangrove zone, a wooden boardwalk trail has been built so you can observe the mangrove ecosystem, with its exposed roots, at eye level.
Visiting Tips
Jozani Forest is located southeast of Stone Town on Zanzibar, so it is usually visited as part of an itinerary combined with the island's southern or eastern beach areas. Entry to the park and use of the trails are generally accompanied by a local guide, and since the colobus are wild animals, you should keep in mind that sightings and their movement routes can vary from day to day. For PlayitTrip users, it is recommended to check entry procedures, guided tour arrangements, and the latest operating information through official local channels such as Tanzania National Parks before visiting. Since the typical course covers both the forest and mangrove areas, it's a good idea to bring comfortable walking shoes and insect repellent.
