Jozani-Chwaka Bay National Park covers roughly 50 square kilometres of southeastern Unguja, protecting the island's last significant patch of indigenous forest alongside a tidal bay fringed by mangroves. It is the only national park in Zanzibar and the single best place on the island to encounter the endangered Zanzibar red colobus monkey in the wild.
Located in Zanzibar
Jozani-Chwaka Bay is where Zanzibar drops the beach-resort script entirely. This is forest, wetland, and tidal bay: a genuinely wild interior that most visitors only glimpse from a car window on their way to the southeast coast, but which rewards anyone who stops and walks.
Jozani-Chwaka Bay sits in the southeastern quarter of Unguja, the main island of the Zanzibar archipelago. The protected area spans roughly 50 square kilometres, stretching from the dense groundwater forest around Jozani village in the interior to the tidal flats and mangrove channels of Chwaka Bay on the Indian Ocean coast. The main visitor entrance and ranger station are on the central road that cuts across the island between Stone Town and the southeast coast villages.
Stone Town lies approximately 35 kilometres to the northwest. The villages of Paje and Jambiani are roughly 15 to 20 kilometres south along the coast. This geographic position makes Jozani a natural midpoint stop on any journey between Stone Town and the southeast beaches, and most organised day trips are structured exactly that way. Chwaka Bay itself faces northeast, opening toward the open ocean, and its shoreline communities have historically depended on fishing and seaweed farming rather than tourism.
The park has no town centre or main street in the conventional sense. The visitor infrastructure concentrates at the main entrance gate near Jozani village: a ticket office, a small information centre, ranger-guided trail departure points, and a car park. Everything else, including the mangrove boardwalk and the bay-side trails, requires walking from that hub. For broader context on how this area fits into a wider Zanzibar itinerary, the one week in Zanzibar guide covers how to sequence a park visit with the coast.
The shift in atmosphere as you leave the coastal road and enter the Jozani forest is immediate and physical. The tree canopy closes overhead, the temperature drops a few degrees, and the light changes from the hard white glare of the beach to something softer and green-tinged. The forest floor is dark red earth, often damp even in the dry season because Jozani sits above a freshwater lens that keeps the groundwater forest alive through months when the rest of the island looks parched.
Mornings are the best time to visit. Before 9 a.m., the forest trails are quiet, the bird noise is at its loudest, and the red colobus troops tend to be active and moving through the lower canopy. By late morning, organised tour groups begin arriving from Stone Town and the north-coast resorts, and the entrance area can become congested around the most frequently visited monkey territory. If you are travelling independently, arriving at opening time is worth the early start.
Afternoons in the forest have a different quality. The tour buses have largely left by 2 p.m., and the trails become quiet again. The light through the canopy turns golden in the hour before dusk, and the mangrove boardwalk, which can feel crowded at midday, becomes almost meditative. The bay side of the park, away from the main forest trails, rarely sees many visitors at any hour, and the tidal channels at low tide have the particular silence of a landscape that is mostly water and mud and birds.
This is not a neighbourhood in the urban sense. There are no restaurants, bars, or guesthouses inside the park boundary. The communities around the park edges, including the fishing villages on Chwaka Bay, live at a pace and on a scale that has little to do with the visitor economy, even though the park is one of Zanzibar's most visited natural attractions. That contrast is part of what makes the area feel genuinely distinct from the resort-heavy coastline.
💡 Local tip
Arrive at the park gate before 9 a.m. to see the red colobus troops before the main tour group rush. Rangers begin guided walks at opening time and group sizes are smallest in the first hour.
The Zanzibar red colobus monkey is the reason most visitors come, and the park delivers reliably. This subspecies is found nowhere else on earth, and Jozani holds the largest surviving population. Troops move through the forest canopy and frequently descend to ground level near the main trail, close enough that no binoculars are needed. Entry to the park includes a ranger-guided forest walk, and the rangers are genuinely knowledgeable about colobus behaviour, tree species, and forest ecology. The Jozani-Chwaka Bay National Park page has full practical details on entry fees and what to expect on the guided walk.
The mangrove boardwalk is a separate trail that leads from the forest edge into a raised wooden walkway over the mangrove channels. It takes about 20 to 30 minutes to complete and offers a completely different ecosystem from the forest: tidal, salt-tolerant, populated by crabs, herons, kingfishers, and the occasional monitor lizard resting on a root system at the waterline. The boardwalk is included in the standard park entry and is accessible without a guide, though rangers can accompany you if requested.
Beyond the main visitor infrastructure, the park contains areas of coral rag forest, a rarer and drier habitat than the groundwater forest around the main entrance, as well as the tidal flats of Chwaka Bay itself. The bay is an important nursery ground for fish and is recognised under the UNESCO Man and the Biosphere Programme, which designated the national park. Birdwatching in the bay-edge habitats is productive, particularly for waders and herons at low tide.
If you are combining natural attractions in a single day, the park is commonly paired with a spice farm visit on the way out from Stone Town, or with a stop at one of the southeast coast beaches afterward. The drive between Jozani and Paje or Jambiani takes roughly 20 to 30 minutes.
⚠️ What to skip
Do not feed the colobus monkeys. Park rules prohibit it, rangers enforce it, and human food is genuinely harmful to their digestive systems. Keep at least three metres of distance at all times and do not crouch or make sudden movements near a troop.
There are no restaurants or cafés inside the park, and the immediate surroundings offer very limited food options. A small refreshment stand near the entrance gate typically sells water, soft drinks, and basic snacks. This is not a place to plan a meal.
If you are driving from Stone Town, the most practical approach is to eat before you leave or pack food for the trip. Visitors heading onward to the southeast coast will find a better range of options in Paje and Jambiani, where beach-facing guesthouses and restaurants serve everything from grilled seafood to wood-fired pizza, at prices well below what you would pay in Stone Town. The drive from the park gate to the first restaurants in Paje takes about 20 to 25 minutes.
For those interested in connecting the park visit to the wider Zanzibari food culture, the Zanzibar food guide covers the island's cooking traditions in detail, including the spice-inflected Swahili cuisine that the region's agricultural landscape helped create.
💡 Local tip
Bring at least 1.5 litres of water per person. The forest feels cool compared to the beach, but the humidity is high and the walks are longer than they look on the trail map. Do not rely on buying water inside the park.
From Stone Town, the most straightforward option is a private taxi or a pre-arranged transfer. The drive takes approximately 45 minutes to one hour depending on road conditions and traffic around Zanzibar Town. Taxis do not operate on meters; agree the fare before departing, and confirm whether the driver will wait during your park visit or return at a set time. A round trip with a waiting period of two to three hours is a common arrangement.
Dala-dala shared minibuses are the budget option. Routes 309 and 310 are reported to serve the Jozani area from Stone Town, though route numbers and stopping points can change. The dala-dala journey takes considerably longer than a taxi due to stops along the route and will typically leave you at or near the park entrance road rather than at the gate itself. For practical guidance on dala-dala travel across the island, the getting around Zanzibar guide explains how the shared minibus system works and what to expect.
Organised day tours from Stone Town and the north-coast resorts typically include transport, park entry, and a guide in a single package. These can be booked through your hotel, any travel agent in Stone Town, or one of the many tour operators along the Stone Town waterfront. The advantage of a tour is convenience; the disadvantage is that you are on the group's schedule and will arrive at peak time with other tour vehicles.
Renting a scooter or car gives the most flexibility: you can arrive early, spend as long as you want, and continue directly to the southeast coast afterward without backtracking to Stone Town. The road from Stone Town to Jozani is tarmacked and in reasonable condition. Inside the park, all movement is on foot on the marked trails.
The park is a natural addition to a day trip from Stone Town, or can anchor the middle section of a longer circuit that includes Kizimkazi dolphin watching to the south and a beach stay on the east coast.
There is no accommodation inside the park boundary. The closest base for visitors who want to spend more than a few hours in the area is the southeast coast, particularly the villages of Paje and Jambiani, both within 20 to 30 kilometres of the park entrance. Staying on the east coast puts the park within easy reach as a half-day excursion and lets you combine it with beach time and the mangrove and seaweed-farming landscapes that characterise that stretch of coastline.
For a wider overview of accommodation options across the island, the where to stay in Zanzibar guide compares the main areas, including the southeast coast, the northern beaches, and Stone Town. If your priority is the national park, the southeast coast lodges are the most practical base, and some of the smaller guesthouses in Jambiani and Paje organise early-morning park transfers for guests.
Travellers whose primary interest is wildlife rather than beaches might also consider pairing a Jozani visit with a wider Tanzania safari, since the park, while excellent for primates and birdlife, is modest in size and best understood as one component of a richer wildlife itinerary. The Zanzibar and Tanzania safari combination guide covers how to structure that kind of trip.
The park is open every day of the year. Entry fees are paid at the gate and are charged in US dollars for non-residents. The fee structure has changed over time, so confirm current prices at the gate or through your accommodation before budgeting. Children are typically charged at a reduced rate.
Wear closed-toe shoes or sturdy sandals for the forest trails. The paths can be muddy after rain, and the mangrove boardwalk occasionally has wet patches even in dry weather. Light, long-sleeved clothing is useful: the forest has mosquitoes, and some sun protection is needed on the more exposed sections of the mangrove trail. A hat and insect repellent are worth carrying.
The park is generally considered safe, and rangers accompany visitors on the main trails. The wider context of safety on the island is covered in the is Zanzibar safe guide, which addresses the practical considerations relevant to most travellers.
Photography is permitted throughout the park. The light under the forest canopy is low, so a camera that performs well in dim conditions will produce better results than a phone camera alone. The colobus monkeys are accustomed to visitors and will often remain still for extended periods, which makes for better photographs than trying to track fast-moving wildlife.
ℹ️ Good to know
Jozani-Chwaka Bay was designated a UNESCO Man and the Biosphere Reserve and became Zanzibar's only national park in 2004. The park protects the island's largest remaining groundwater forest and is the core habitat for an estimated total Zanzibar red colobus population of 5,862, a subspecies found nowhere else in the world.
Jozani Chwaka Bay National Park is Zanzibar's only national park, protecting ancient groundwater forest, coastal mangroves, and the endangered Zanzibar red colobus monkey across roughly 50 square kilometres of southern Unguja. It is a serious nature destination, not a theme park, and rewards patient visitors who arrive early and move quietly.
