While Zanzibar is world-famous for its pristine white sands and turquoise waters, the island hides a verdant secret in its interior. Jozani Chwaka Bay National Park is the island’s only national park and a critical biodiversity hotspot. Spanning approximately 50 square kilometers, this protected area offers a rare glimpse into the ancient indigenous flora and fauna that once covered the entire archipelago. Whether you are a wildlife photographer, a nature enthusiast, or a traveler looking to escape the beach for a day, Jozani Forest offers an unforgettable encounter with nature. This comprehensive guide covers everything you need to know, from spotting the rare Red Colobus monkeys to navigating the park’s enchanting mangrove boardwalks.
Established as a national park in 2004, Jozani Chwaka Bay is more than just a forest; it is a sanctuary for endangered species and a triumph of community-based conservation.
The park’s undisputed stars are the Zanzibar Red Colobus monkeys (Piliocolobus kirkii). Unlike their shy cousins on the mainland, these primates are endemic to Unguja (Zanzibar’s main island), meaning they are found nowhere else on Earth. With a population of roughly 2,000 to 2,500, they are an endangered species. However, they are remarkably habituated to humans. Visitors can often observe them at close range as they play, groom, and feed on leaves in the lower branches. Their distinctive white hair, rusty-red back, and expressive faces make them a photographer’s dream.
Jozani is an ecological marvel. It is not a single uniform forest but a mosaic of diverse habitats. The park creates a transition zone from the interior groundwater forest—where ancient mahogany and palm trees rely on the high water table—to the coastal coral rag forests and finally the salt marshes and mangroves of Chwaka Bay. This variety allows a diverse range of species to thrive in a relatively small area.
While the monkeys steal the show, the park teems with other life. Keep your eyes peeled for Sykes’ monkeys (also known as Blue monkeys), which are often seen high in the canopy. The forest is also home to the shy Ader’s duiker, bushbabies, and over 40 species of birds, including the mangrove kingfisher and little greenbul. Locals may also tell you whispers of the Zanzibar Leopard, a mythical apex predator officially considered extinct, though rumors of sightings persist among island elders, adding an air of mystery to the dense undergrowth.
A typical visit to Jozani is split into two distinct parts: the forest nature walk and the mangrove boardwalk.
Upon arrival, you will be assigned an official park guide (included in your entrance fee). The tour begins with a walk through the lush groundwater forest. Your guide will point out medicinal plants used by locals for centuries, towering mahogany trees, and, of course, the Red Colobus troops.
After the forest trail, a short drive or walk takes you to the other side of the main road to the Mangrove Boardwalk. This elevated wooden path winds through a dense mangrove forest that thrives where the land meets the sea. It is a serene, almost otherworldly experience. Depending on the tide, you might see the twisted roots submerged in water or standing tall in the mud. Look closely at the mud below to spot thousands of fiddler crabs waving their oversized claws and mudskippers hopping between puddles. This ecosystem acts as a natural nursery for fish and protects the island from coastal erosion.
Located just near the park (often combined in tours) is the Zanzibar Butterfly Centre. It is a community conservation project where you can walk through a netted tropical garden filled with hundreds of colorful butterflies native to Zanzibar. It is a fantastic add-on, especially for families with children.
The park is open year-round, but the Dry Season (June to October and January to February) is the most comfortable time to visit. During these months, the trails are less muddy, and the humidity is lower.
Visiting Jozani Chwaka Bay National Park is a highlight of any Zanzibar itinerary. It provides a vital connection to the island’s natural history and directly supports the conservation of one of Africa’s rarest primates. Whether you spend an hour or a half-day here, the sight of a Red Colobus leaping through the mahogany trees is a memory that will last a lifetime.
arose58 This is a nice wilderness walk but the only animals we saw were the monkeys at the very front of the park. The monkeys come very close to people but you are to stay 3 meters away. The mangrove is about a 15 min drive from the forest.
Yvonette Aiko Koyama There's is enough red monkeys to see and information about the forest is interesting. To take note, go with water shoes or sandals that you can get dirty as it is a tropical weather forest, there's sure to be muddy area where you will walk!
Caroline Crutchley An amazing insight into the only surviving forest in Zanzibar. Protection from Tsunami and even climate change. Once under a coral ocean it is now strong mahogany trees and mangroves . Find the monkeys that are only found in this forest. Guides are well informed.
Ιωαννης Αντωνακης Beautiful experience because we went at the right time (08:40) we had a private tour because there were only people there, we saw animals and plants our guide Amur was very informative and patient, the money from the entrance ticket is used for the maintenance of the forest and for protection. The duration of the tour varies, it can be up to two or three hours for those who have a lot of questions and want to know everything.
Aneesa My god, what a fantastic place. Just myself and 2 other people with a brilliant tour guide. As a monkey fanatic, naturally I absolutely loved it; getting to see the monkeys in their natural habitat, as well as so up close and personal was such a dream of mine. Monkeys seem to be very relaxed around humans too. The mangrove tree forest afterwards was also so unique, and your guides takes some photographs for you. Just such an unplanned yet magical day - one of my highlights of Zanzibar.
