Chimpanzee trekking in Tanzania happens mainly in two remote western parks, Mahale Mountains and Gombe, both on the shore of Lake Tanganyika, where habituated communities of wild chimpanzees can be followed on foot through the forest. These are the country’s only reliable chimp-trekking destinations, reached by flying west from the northern safari hubs. A trek pairs a forest hike of thirty minutes to several hours with about one hour beside the group once trackers find it.
Chimpanzee Trekking Safari in Mahale Mountains National Park
The Mahale Mountains offer the most celebrated chimpanzee trekking in Tanzania. The park protects a large wild population, and one community known as the M group has been studied since Japanese researchers began work here in the 1960s, which is why these chimps accept human visitors at close range.
A Mahale chimpanzee trekking safari starts with trackers locating the group, then a hike uphill through dense forest that rises straight from the lake. Some mornings the walk is short, other days it climbs steeply for hours. The forest here is thick and the mountains high, topping out above 2,400 metres, so a reasonable level of fitness helps. Sightings are strong by wild-primate standards but never certain, since the chimps roam where the fruit is.
Gombe Stream Chimpanzee Tracking Tours
Gombe Stream National Park is the smaller and more historic of the two, and the place where Jane Goodall began her long study of wild chimpanzees in 1960. That research made Gombe one of the most important primate sites in the world, and its habituated chimps remain the focus of visits today.
Being compact, Gombe often gives shorter treks than Mahale, though the terrain is still hilly and forested. Beyond the chimps, the park holds red colobus, olive baboons and a good range of birds, and the same clear waters of Lake Tanganyika lap its shore. It is reached by boat from Kigoma, which sits at the end of a long overland or flight route from the rest of the country.
What a Chimpanzee Trekking Adventure Involves
A chimpanzee trekking adventure follows a fairly set rhythm. Groups are small, guides and trackers lead the way, and once the chimps are located visitors are usually allowed a single hour with them. Wearing a face mask is required to protect the animals, who share much of our biology and can catch human illnesses.
The chimps are active and loud when you find them, feeding, grooming, squabbling and moving through the trees, so photography can be tricky in the low forest light. Keeping the required distance is part of the rules, though the chimps do not always read the rulebook and sometimes pass close by on their own terms.
Permits are limited each day, which keeps group sizes small and the pressure on the animals low. There is usually a minimum age of around fifteen for trekkers, and anyone showing signs of a cold or flu may be turned back at the briefing to protect the group. Guides brief every party on the rules before setting out, covering how to behave around the chimps, what to do if one approaches, and how to move quietly through the forest so the group stays relaxed.
Physically, come ready for humidity and uneven ground. Long trousers, closed shoes with grip and a light rain layer all earn their place, and a walking pole is worth having on the steeper descents. The reward for the effort is time with animals that share close to ninety-eight percent of their DNA with us, watching family behaviour play out at close range in the wild rather than through glass.
Best Time for Chimpanzee Trekking in Tanzania
The dry season, roughly May to October, is the most reliable window for chimpanzee trekking in both Mahale and Gombe. Drier weather often brings the chimps lower down the slopes, which shortens the hikes, and the forest trails are firmer and less slippery. The lake is also calmer for the boat transfers that both parks depend on.
The table below compares the trekking seasons across the western parks.
| Season | Months | Trekking conditions |
|---|---|---|
| Dry season | May to October | Chimps often lower on the slopes, shorter treks, firm trails, calm clear lake. Peak period. |
| Short rains | November to December | Green forest, passing showers, fewer visitors, treks can be longer. |
| Long rains | March to April | Heaviest rain, slippery trails, some camps close, access harder. |
| Warm interval | January to February | Drier spell, good trekking, hot and humid by the lake. |
How to Reach Tanzania’s Chimpanzee Trekking Parks
Both parks sit in the far west and neither has a normal road link that safaris use. The usual route to Mahale is a light-aircraft flight from Arusha or the Serengeti to a nearby airstrip, then a boat transfer along Lake Tanganyika to your camp. Gombe is reached by flying or driving to Kigoma, then taking a boat up the lake to the park.
Because of the effort and cost of getting there, chimpanzee trekking is usually built into a wider Tanzania itinerary rather than done alone. Travellers frequently open with the northern circuit, taking in the elephants and baobabs of Tarangire National Park, before flying west for the forests and the lake.
Chimpanzee trekking is one of several ways to see great apes in the region. Tanzania has the lakeside chimps of Mahale and Gombe, while over the border the forests of Rwanda are known for both gorillas and the chimpanzees of Nyungwe, covered in guides to Rwanda primate trekking.
Where to Stay for a Chimpanzee Trekking Safari
Accommodation in both parks is limited and mostly upper-tier, a reflection of how much it costs to supply a camp with no road access. Mahale has a small cluster of lakeside camps, while Gombe offers a park-run rest house and a lodge or two. Beds are few in either park, so booking well ahead is important in the dry-season peak, and the trade-off for the price is trails that rarely feel crowded.

Frequently Asked Questions
How much does chimpanzee trekking in Tanzania cost?
Costs vary by park and season, but plan on a park entry fee plus a separate chimpanzee permit, together running to a few hundred US dollars per person per day. Flights and boat transfers to the western parks add a large amount on top, which is why chimp trekking is usually priced as part of a multi-day package.
Where can you go chimpanzee trekking in Tanzania?
The two main parks are Mahale Mountains and Gombe Stream, both on Lake Tanganyika in the west. Mahale is larger with a big wild population, while Gombe is smaller and historically tied to Jane Goodall’s research.
Is chimpanzee trekking difficult?
It can be. Treks range from short and easy to steep, slippery climbs of two or three hours through forest. A moderate level of fitness and sturdy footwear make it manageable for most active visitors, and guides set the pace.
Are chimpanzee sightings guaranteed?
No. The habituated groups are usually found most days in the dry season, so the odds are good, but these are wild animals in dense forest. Weather and feeding patterns can lengthen a search or occasionally prevent contact.
How is chimpanzee trekking different from gorilla trekking?
Chimps are faster, noisier and more spread through the canopy, so treks can cover more ground and sightings feel more active. Gorillas, found in Rwanda and Uganda rather than Tanzania, tend to stay lower and calmer on the forest floor.
When is the best time for chimpanzee trekking in Tanzania?
The dry months from May to October are the most reliable, with firmer trails and chimps often lower on the slopes. The green season is quieter but wetter, and some camps close during the long rains of March and April.
