How Many Mountain Gorillas Live in Rwanda?
Rwanda is home to approximately one-third of the world’s remaining mountain gorilla population. As of the most recent census data, roughly 400 mountain gorillas live within and around Rwanda’s Volcanoes National Park — part of a total global mountain gorilla population of approximately 1,063 individuals (as counted in the 2018 census, the most recent complete count available at time of writing).
This number — one-third of a global total of just over 1,000 — defines the stakes of mountain gorilla conservation and explains the importance of every decision made about their management.
Where Rwanda’s Gorillas Live
Rwanda’s mountain gorillas live within the Virunga Massif — the chain of eight volcanoes shared between Rwanda, Uganda, and the Democratic Republic of Congo. The Rwandan portion of this range, protected by Volcanoes National Park, covers approximately 160km² of high-altitude volcanic forest between 2,400 and 4,507 metres. This is a small area relative to the ecological requirements of large primates, which is why the Virunga gorilla population as a whole shares territory across three countries rather than existing within a single national boundary.
Rwanda also shares gorilla territory with Bwindi Impenetrable National Park in Uganda through the Bwindi-isolated population, which numbers approximately 459 individuals and is classified as a separate subpopulation from the Virunga population. Rwanda’s mountain gorillas are part of the Virunga subpopulation; Uganda’s Bwindi gorillas are genetically distinct.
The Census Methodology
Mountain gorilla population counts are conducted through a combination of direct observation (for habituated families whose members are individually known) and sign surveys (nest counts, fresh dung, footprints) for non-habituated individuals living in remote sections of the park. The most recent complete Virunga census, conducted in 2015–2016 with results published in 2018, counted 604 mountain gorillas in the Virunga range — of which a significant proportion live in or regularly use the Rwandan section of the park.
Of these, more than 12 gorilla families at Volcanoes National Park are fully habituated for trekking visits, with additional research families habituated for scientific observation but not open to regular tourist access.
The Conservation Story — From 254 to More Than 1,000
The mountain gorilla population was estimated at approximately 254 individuals in 1981. The species was widely considered to be heading toward extinction. The combination of Dian Fossey’s research at the Karisoke Research Centre, the establishment and enforcement of national park protection across the Virunga range, the development of the gorilla tourism economy (which created economic value in gorilla conservation), and the anti-poaching operations of RDB, UWA, and ICCN in Rwanda, Uganda, and DRC respectively produced a recovery that now constitutes one of the most significant conservation successes of the 20th and 21st centuries.
The population crossed 1,000 individuals for the first time in the 2018 census — the threshold at which the IUCN downgraded the species’ classification from Critically Endangered to Endangered. This is a significant distinction: it means the immediate extinction risk has receded, though the species remains vulnerable and the conservation infrastructure that produced the recovery must be maintained for the numbers to hold.
Rwanda’s Contribution to the Recovery
Rwanda’s contribution to the gorilla population recovery is directly connected to the gorilla tourism economy. Permit revenue — $1,500 per standard permit, $15,000 for Exclusive and Behind the Scene products — funds the anti-poaching ranger force that patrols Volcanoes National Park continuously, the health monitoring and veterinary intervention programme run by Gorilla Doctors, and the community revenue sharing that gives communities adjacent to the park a direct economic stake in gorilla survival. Visiting gorillas in Rwanda is, in a direct and measurable sense, contributing to the continued existence of the species.
How Many Gorilla Families Can You Trek in Rwanda?
As of 2025, Rwanda has more than 12 habituated gorilla families available for trekking visits at Volcanoes National Park. Each family is assigned a maximum of eight visitor permits per day; the total daily visitor footprint across all families is therefore capped at approximately 96 permitted visitors. This controlled access is both a conservation measure and a quality-of-experience decision — the encounter is meaningful partly because it is rare.
