Wild gorillas live in a handful of countries across central and east Africa, and you can visit them in roughly half a dozen national parks. The experience you get depends on which subspecies you’re looking for: mountain gorillas in Rwanda, Uganda, and the Democratic Republic of Congo, or western and eastern lowland gorillas in countries like the Republic of Congo and Gabon. With a global mountain gorilla population that has climbed past 1,000 individuals, conservation-funded tourism is a major reason these animals still exist.
Mountain Gorillas in Uganda
Uganda is the most popular destination for mountain gorilla trekking, and it offers two parks. Bwindi Impenetrable National Park is the flagship location, home to roughly half the world’s mountain gorillas across multiple habituated family groups. The dense, steep forest means treks can take anywhere from one to six hours depending on where the gorillas happen to be that day, but trackers head out before dawn to locate the group, and your chances of a sighting are above 95 percent.
Mgahinga Gorilla National Park, in Uganda’s far southwest corner, is smaller and less visited. It sits along the Virunga volcanic range and has fewer habituated groups, which means fewer permits are available on any given day. That can work in your favor if you prefer a quieter experience.
Uganda also offers something no other country does: the gorilla habituation experience. Available only in the Rushaga sector of southern Bwindi, this lets you spend up to four hours with a gorilla family that is still being acclimated to human presence, rather than the standard one-hour visit. A habituation permit costs $1,500, compared to $800 for a standard trekking permit for foreign visitors.
Mountain Gorillas in Rwanda
Volcanoes National Park, in Rwanda’s northwestern corner, is the country’s sole gorilla trekking destination. It sits in the Virunga Mountains, the same volcanic chain made famous by primatologist Dian Fossey. The park’s terrain is generally considered slightly easier to navigate than Bwindi’s thick jungle, and treks often start at higher elevations on the volcano slopes.
Rwanda positions itself as a premium destination. A single gorilla permit costs $1,500 for international visitors, nearly double Uganda’s price. East African citizens pay $200. The higher cost funds conservation work and keeps visitor numbers low, but it also means Rwanda draws travelers who want a more polished, less rugged experience. The park is only about two hours from Kigali, making logistics simpler than Uganda’s longer overland transfers.
Mountain Gorillas in the DRC
Virunga National Park in the eastern Democratic Republic of Congo is Africa’s oldest national park and home to habituated mountain gorilla groups. Permits historically cost around $400, making it the most affordable option by far. However, Virunga closed to tourism in March 2020 due to security concerns in the region and has not consistently reopened since. If it is open when you plan your trip, you should check the current security situation carefully, as political instability in eastern Congo has been an ongoing issue for decades.
Eastern Lowland Gorillas in the DRC
Kahuzi-Biega National Park, also in eastern Congo, is the primary place to see Grauer’s gorillas, the eastern lowland subspecies. These are the largest of all gorillas and are critically endangered, with only around 250 individuals in the park’s highland sector. The park straddles the Albertine Rift and Congo Basin, creating a lush habitat of montane and lowland rainforest between 2,100 and 2,400 meters elevation.
Trekking at Kahuzi-Biega is currently possible, but the park faces serious challenges. Poaching, artisanal mining, and the displacement of local populations due to regional conflict have all degraded the park’s resources. UNESCO lists it as a World Heritage Site in Danger. Visiting here is a more adventurous, less predictable experience than the well-oiled tourism operations in Uganda and Rwanda.
Western Lowland Gorillas in Central Africa
Western lowland gorillas are far more numerous than their mountain cousins (an estimated 100,000 or more exist), but they are paradoxically much harder to see. They live in dense lowland rainforest across Gabon, the Republic of Congo, Cameroon, and the Central African Republic, where thick vegetation and their skittish nature make sightings less reliable than mountain gorilla treks.
In the Republic of Congo, Odzala National Park is the best-known option. The park has several habituated western lowland gorilla groups and runs multi-day trekking programs through its swampy forest clearings, called “bais,” where gorillas come to feed. The experience is more remote and expedition-style compared to East African treks.
Gabon offers gorilla viewing at Loango National Park, a coastal park with forest, savannah, and lagoons where you may also see elephants, hippos, and whales offshore. Moukalaba-Doudou National Park has some of the highest gorilla densities in the country and is developing eco-tourism infrastructure. There is also a gorilla rehabilitation sanctuary on an island in the Fernan Vaz Lagoon, though these are rescued animals rather than wild gorillas.
What Trekking Actually Involves
Gorilla trekking is a guided hike through dense tropical forest, not a game drive. You walk through mud, climb steep hillsides, and push through thick undergrowth. The trek itself can last anywhere from one to six hours each way depending on where the gorillas are that morning. Park rangers locate the group before you set out, which is why sighting success rates are so high. Once you reach the gorillas, you get one hour to observe them (four hours if you’re doing Uganda’s habituation experience).
Groups are capped at eight tourists per gorilla family per day. You must stay at least seven meters from the gorillas at all times, and face masks are required or strongly recommended to prevent respiratory disease transmission. Gorillas are highly susceptible to human illnesses, and a single cold virus could devastate a group. If you’re visibly sick on trek day, you will not be allowed to participate.
The minimum age is 15, with no upper age limit. You don’t need to be an athlete, but you should be able to walk for several hours over uneven, hilly terrain. Most parks offer the option of hiring a porter to carry your bag and help you over difficult sections, which is worth considering regardless of fitness level.
Permits, Costs, and Timing
Permits sell out, sometimes months in advance during peak season. Current prices for international visitors: $1,500 in Rwanda, $800 in Uganda, and $400 in the DRC. These are per person, per trek. You book through the national wildlife authority or through a licensed tour operator, and permits are non-transferable.
The best months to trek are during the two dry seasons: June through September and December through February. Trails are less muddy, the forest floor is more navigable, and the overall experience is more comfortable. That said, gorillas can be trekked year-round. The wet season (March through May, October through November) brings fewer tourists and sometimes lower permit availability pressure, but the hikes are significantly harder in the mud.
Most travelers book gorilla trekking as part of a larger safari or multi-day itinerary. In Uganda, the drive from Kampala to Bwindi takes eight to ten hours, so most people fly to a nearby airstrip or combine the trek with other parks. Rwanda’s Volcanoes National Park is far more accessible from the capital. For western lowland gorilla destinations in Gabon or Congo, expect bush flights and remote lodge stays as part of the logistics.
