Gorillas and chimpanzees understandably dominate most primate-focused safari planning in East Africa, but the region is home to a considerably wider cast of primate species, many of them found nowhere else on earth and each offering a genuinely distinct encounter from the two headline great apes. Golden monkeys bouncing through bamboo thickets, red colobus troops moving through Kibale’s canopy in numbers that can exceed a hundred individuals, and the strange, haunting calls of black-and-white colobus at dawn all offer primate experiences that many travellers, fixated purely on gorillas and chimps, never discover. Building one or two of these lesser-known primate encounters into an itinerary rounds out a trip considerably, often for a fraction of the cost of a single gorilla permit.
This guide surveys the best of East Africa’s other primates, where to find them, and how they fit alongside a gorilla or chimpanzee trekking itinerary.
Golden Monkeys: The Closest Rival to Gorillas and Chimps
Golden monkeys are found only in the Virunga Massif and immediately surrounding areas spanning Rwanda, Uganda and DR Congo, making them almost as geographically restricted as mountain gorillas themselves. Their striking orange-gold fur, playful, highly social troops often numbering forty or more individuals, and relatively easy, low-altitude bamboo forest habitat make tracking them a considerably less physically demanding activity than gorilla trekking, typically completed within one to two hours rather than a full day.
At around $100 per person in both Rwanda and Uganda, golden monkey tracking costs a small fraction of a gorilla permit, making it an easy, worthwhile addition for travellers already visiting Volcanoes National Park or Mgahinga Gorilla National Park who want a second primate encounter without a significant additional time or cost commitment.
Why Golden Monkeys Suit Families and Less Fit Travellers
The comparatively gentle terrain and shorter duration of golden monkey tracking make it a genuinely good option for travellers who want a primate encounter but are concerned about gorilla trekking’s physical demands, or for families with younger children below gorilla trekking’s minimum age of fifteen.
Red Colobus and Black-and-White Colobus in Kibale Forest
Kibale Forest National Park, already known internationally for chimpanzee trekking, also hosts thirteen primate species, the highest diversity of any East African forest, including large troops of red colobus monkeys recognisable by their reddish-brown backs and strikingly patterned faces. Red colobus troops in Kibale can number well over a hundred individuals, creating a genuinely spectacular sight as they move through the canopy together, a scale of primate activity that neither gorilla nor chimp trekking typically offers.
Black-and-white colobus, with their long, flowing white tail and cape-like fur, are somewhat easier to spot than red colobus and are frequently seen even from vehicles travelling through Kibale or Nyungwe, making them one of the more accessible primate sightings available without any dedicated tracking activity or permit required at all.
L’Hoest’s Monkeys and Blue Monkeys
L’Hoest’s monkeys, a striking dark-coated species with a distinctive white beard, inhabit the same forests as gorillas and chimps but are considerably more elusive, often glimpsed briefly on the forest floor rather than tracked deliberately, adding an unplanned bonus sighting to many gorilla or chimp treks rather than being a dedicated destination in their own right. Blue monkeys, despite the name, display more of a grey-blue sheen than true blue colouring and are among the more commonly encountered forest primates across Uganda, Rwanda and Tanzania, often seen moving through mid-canopy vegetation during almost any forest walk.
Vervet Monkeys and Baboons Beyond the Forest
Outside the dense rainforest habitats favoured by gorillas and chimps, savannah-adapted primates like vervet monkeys and olive baboons are almost impossible to avoid across East Africa’s national parks and even many lodge grounds, offering visitors an ever-present, low-effort primate presence that requires no dedicated tracking activity whatsoever. While less exotic to experienced safari-goers than the forest specialists, these savannah primates remain a genuine highlight for first-time visitors unfamiliar with primate behaviour, and their habituation to human presence around lodges often provides considerably closer, more relaxed viewing opportunities than any tracked forest species.
Nyungwe Forest: A Concentrated Primate Hotspot
Rwanda’s Nyungwe Forest National Park hosts thirteen primate species within a single, relatively compact protected area, including chimpanzees, L’Hoest’s monkeys, and large troops of Angola colobus, a subspecies found in particularly striking concentrations along the park’s canopy walkway trail. Visitors combining gorilla trekking in Volcanoes National Park with a few additional days in Nyungwe can realistically encounter five or six different primate species within a single trip, a level of primate diversity difficult to match almost anywhere else on the continent.
The Canopy Walk as a Primate Viewing Platform
Nyungwe’s suspended canopy walkway, one of relatively few of its kind in Africa, offers an unusually elevated vantage point for observing primates moving through the upper forest canopy, a genuinely different viewing angle from the ground-level encounters typical of gorilla and chimp trekking elsewhere.
Building a Multi-Primate Itinerary
Travellers with enough time to spare benefit considerably from combining several of these species into a single, deliberately planned primate-focused itinerary rather than treating gorillas or chimps as the sole objective. A realistic itinerary might combine gorilla trekking and golden monkey tracking in Rwanda’s Volcanoes National Park, followed by a few days in Nyungwe for chimpanzees and colobus troops, or in Uganda, pairing Bwindi gorilla trekking with Kibale’s chimpanzee and red colobus populations for a similarly diverse primate-focused trip.
Because most of these secondary primate activities cost considerably less than a gorilla or chimp permit and require no advance booking in the same way gorilla permits do, they are relatively easy to add into an existing itinerary without the scheduling pressure that governs the headline activities.
Tanzania’s Primate Options Beyond Gombe and Mahale
While Tanzania’s chimpanzee populations at Gombe and Mahale Mountains attract most attention, the country’s broader forest reserves and national parks host additional primate diversity worth considering for travellers already exploring Tanzania’s northern or western circuits. Vervet monkeys and baboons are common across the Serengeti and Ngorongoro Conservation Area, and the Udzungwa Mountains, part of the Eastern Arc range sometimes described as Africa’s Galapagos for their high level of species endemism, host the Sanje mangabey, found nowhere else on earth, alongside several other localised primate species rarely encountered by typical safari itineraries focused purely on the northern parks.
Travellers with a serious interest in primate diversity specifically, rather than the more general wildlife viewing that dominates most Tanzania itineraries, may find a dedicated detour to the Udzungwa Mountains worthwhile, though this requires considerably more planning and off-the-beaten-path travel than the standard northern circuit most visitors follow.
Cost Comparison Across Different Primate Activities
Understanding the relative cost of these different primate activities helps with realistic budgeting for a multi-primate itinerary. Golden monkey tracking at roughly $100 per person and standard chimpanzee trekking at $150 to $250 depending on country both sit considerably below gorilla trekking’s $800 to $1,500 range, while colobus and other non-permitted primate sightings that occur simply as part of a broader forest walk or game drive carry no additional cost at all beyond the underlying park entrance fee. This pricing structure means a genuinely diverse, multi-species primate itinerary need not carry a proportionally multiplied cost, since the most expensive single activity, gorilla trekking, can be supplemented with several lower-cost or free additional primate encounters without dramatically inflating the overall trip budget.
Why Primate Diversity Matters Beyond the Headline Species
Beyond the simple appeal of seeing more species, East Africa’s broader primate diversity reflects the genuine ecological richness of its remaining forest habitats, and encountering this diversity firsthand often deepens a traveller’s understanding of gorilla and chimpanzee conservation itself, since these headline species do not exist in isolation but as part of a much larger, interconnected forest ecosystem worth protecting as a whole rather than piece by piece.
Our guides on East Africa’s primate diversity beyond gorillas and chimps and the golden monkey of the Virunga Mountains cover several of these species in additional depth. Our overview of Nyungwe Forest’s tea estate trail offers a useful look at a different side of one of the region’s most primate-rich parks. The IUCN Red List maintains current conservation status information for each of these species, useful background for travellers wanting to understand how threatened, or relatively secure, each population currently is.
For most travellers, the most practical approach is simply to ask a knowledgeable operator, while planning a gorilla or chimpanzee-focused itinerary, which additional primate encounters are realistically achievable within the same trip without significant extra cost or travel time. More often than not, the answer reveals that a single well-planned East Africa trip can deliver a far richer primate experience than the headline gorilla trekking or chimp trekking activity alone would suggest, turning what many travellers plan as a single-species pilgrimage into a genuinely comprehensive primate safari that showcases the full breadth of what these forests actually hold, well beyond the two famous great apes that first drew them to the region, and leaves most visitors already planning their next trip before the current one has even ended.
