Nyungwe Forest Chimp Trek: Rwanda’s Montane Rainforest Circuit

Nyungwe Forest National Park in south-western Rwanda is one of Africa’s most significant and least visited montane forest destinations: 1,019 square kilometres of ancient highland rainforest on the Congo-Nile divide ridge at altitudes of 1,600 to 2,950 metres above sea level, harbouring one of the continent’s most diverse primate communities and representing the largest single montane forest block in Central Africa. While Volcanoes National Park in the north dominates Rwanda’s international wildlife profile, Nyungwe offers a profoundly different and in some ways rarer experience: a cathedral forest of enormous tree ferns, ancient hagenia woodland, and dense mossy rainforest inhabited by 13 primate species, the endemic Rwenzori turaco and over 280 other bird species, and a chimpanzee community that can be trekked with guides through the steep terrain of the Congo-Nile watershed. The canopy walkway above the Igishigishigi area — a 200-metre suspension bridge at 50 metres above the forest floor — provides the most accessible and visually dramatic primate encounter in the park as habituated Angola colobus troops move through the canopy at eye level from the platform. This page covers the full self-drive guide for the Nyungwe chimp trek circuit, including the drive from Kigali, the chimpanzee trekking procedure, the canopy walkway, the forest trail network, and accommodation in the Nyungwe area.

The Chimpanzee Trek at Nyungwe Forest

Chimpanzee trekking at Nyungwe Forest is organised by the Rwanda Development Board through the Uwinka visitor centre on the main road through the park (RN1 highway, 225 kilometres south-west of Kigali). The habituated chimpanzee community at Nyungwe lives in a large group that occupies the Uwinka and Cyamudongo sections of the forest and can be trekked with an RDB guide on a permit system similar to the gorilla trekking model. The Nyungwe chimpanzees move in a dense forest environment significantly more challenging for trekking than the Uganda chimpanzee habitats at Kibale and Budongo, where the forest floor is more open and the terrain is flatter. The Nyungwe terrain is characterised by steep ridges separated by deep stream valleys, extremely dense understorey vegetation, and trails that involve significant climbing on root-covered paths. The standard approach walk to find the chimpanzee community typically takes 1 to 3 hours depending on the community’s location in their range, and the subsequent observation period is 1 hour as specified in the Rwanda Development Board’s primate trekking regulations. Nyungwe’s chimpanzees are active in a larger home range than the smaller habituated communities in Uganda’s Kibale Forest, and their movement through the steep terrain is correspondingly fast and physically demanding to follow. The Cyamudongo Community Forest, an isolated forest patch 15 kilometres south of the main Nyungwe park on the road toward Burundi, contains a separate habituated chimpanzee community in a smaller forest fragment that can be tracked with a community-based guide programme. The Cyamudongo population is believed to be the southernmost chimpanzee community in Central Africa and is of particular scientific interest as an isolated relict population separated from the main Nyungwe forest block.

What distinguishes the Nyungwe chimpanzee encounter from the Kibale or Budongo experience is the forest itself. While Kibale is a productive-but-secondary forest thinned by decades of tree-extraction and relatively open on the ground, Nyungwe is an ancient primary forest in which the canopy closes 40 to 50 metres above the trail, the understorey is dense and multi-layered, the light is dim and green-filtered, and the sense of ecological antiquity and undisturbed complexity is palpable at every step. The sounds of Nyungwe compound this effect: the haunting pant-hoot vocalisations of the chimpanzee community echoing through the ridge-and-valley topography, the calls of the Rwenzori turaco and the mountain masked apalis, and the deep silence of the dense vegetation between them. The Nyungwe chimpanzee trek is the most atmospheric primate encounter in East Africa for visitors who value the forest environment as much as the animal itself, and it rewards a 2 to 3 night stay that allows multiple walks through the forest network, the canopy walkway visit, and the dawn chorus birding session before the breakfast.

The Canopy Walkway: Angola Colobus at Eye Level

The Nyungwe canopy walkway is a 200-metre suspension bridge system at approximately 50 metres above the forest floor in the Igishigishigi area, reached by a 45-minute uphill trail from the Uwinka visitor centre. The walkway is accessible to visitors without a trekking permit (a separate canopy walkway fee is charged) and represents the most accessible wildlife encounter in the park. The Angola colobus monkey (Colobus angolensis ruwenzorii), a large black-and-white colobus with spectacular white shoulder mantle and tail fringe, has habituated to the presence of visitors on the walkway platform and the adjacent canopy. Troops of 30 to 60 individuals regularly traverse the canopy adjacent to the walkway, leaping between branches within 10 metres of the platform and providing a canopy-level encounter with one of the most visually striking primates in Africa. The walkway is the most reliable wildlife photography platform in Nyungwe for visitors who are not undertaking the chimpanzee trek: the elevated position provides clear sightlines through the canopy that are unavailable on the forest floor, the colobus habituation means close approach without disturbance, and the morning light on a clear day illuminates the white mantle of the adults against the forest green with remarkable photographic effect. The trail from the Uwinka visitor centre to the walkway is steep and takes 30 to 45 minutes uphill, with the return taking approximately 25 minutes downhill. The walk itself passes through different forest zones and is productive for forest birds including the green-headed sunbird, white-starred robin, and various greenbul species. Visitors to the canopy walkway should arrive at the Uwinka visitor centre by 7:30 am to complete the fee payment and begin the walk before the colobus troop moves away from the walkway’s immediate area later in the morning.

Nyungwe Forest Birding: The Congo-Nile Divide Species

Nyungwe Forest National Park is Rwanda’s most important birding destination, with a bird list of over 280 species including a significant number of Albertine Rift endemic species found only in the highland forests of the Congo-Nile divide from Uganda south through Rwanda and Burundi to Tanzania. The Albertine Rift endemics at Nyungwe include the Rwenzori turaco (one of the most spectacularly coloured turacos in Africa, with green, blue, and crimson plumage), the Grauer’s broadbill, the African green broadbill, the doherty’s bushshrike, the Rwenzori nightjar, the dusky crimsonwing, and 16 additional endemic or near-endemic bird species. The diversity of altitude zones within the park — from 1,600 metres at the tea plantation boundary to 2,950 metres at the park’s highest ridge — compresses several distinct forest bird communities into a relatively small area, and the transition zones between the Afroalpine heath at high altitudes and the lower-altitude rainforest are particularly productive for the specialist birder. The forest canopy from the suspension walkway provides the best elevated platform for canopy-dwelling species that are essentially invisible from the forest floor below. Dawn birding sessions beginning at first light from the Uwinka visitor centre or the park accommodation overlook are the most productive for high-species-count birding lists. The best birding period at Nyungwe is April to May (the breeding season and the period when Palaearctic migrants are still present) and September to November.

The 13 Primate Species of Nyungwe: Beyond the Chimpanzee

Nyungwe Forest National Park’s chimpanzee population is the headline primate attraction, but the forest contains 12 other primate species that make it the most diverse non-chimpanzee primate community in East Africa outside of the Congo Basin forests to the west. The grey-cheeked mangabey (Lophocebus albigena) is a large, dark-furred monkey of the forest canopy that moves in troops of 20 to 40 individuals with a distinctive loud honking call audible across the ridge when a troop is disturbed. L’Hoest’s monkey (Cercopithecus lhoesti), also called the mountain monkey, is a striking medium-sized monkey with a chestnut mantle, white beard, and deep black face that frequents the forest floor and undergrowth more than the canopy, making it one of the more regularly encountered primates on forest trail walks. The olive baboon (Papio anubis) is the only papionid monkey present at Nyungwe and occupies a distinct ecological role from the more arboreal species: baboon troops are frequently seen at the forest edge and along the main road through the park, and their robust size (up to 30 kilograms for adult males) and the alarm calls of the troop are useful indicators of chimp presence when the chimpanzee community is in the same area of the forest. The demidoff’s galago (Galagoides demidoff), Africa’s smallest primate at approximately 60 grams, is the only primate at Nyungwe that requires a spotlight to see — a wholly nocturnal species visible only on night walks with an RDB guide. The Rwenzori colobus is the dominant Nyungwe primate in terms of total population and visibility: troops of the black-and-white colobus are reliably seen at the canopy walkway, on forest trails, and in the woodland patches at the forest margins throughout the day. A dedicated primatologist visiting Nyungwe for 3 to 4 days with the full RDB primate trekking programme can realistically encounter 8 to 10 of the 13 species in a single circuit, making Nyungwe the highest-concentration primate experience in a compact area available anywhere in East Africa.
