Best Time for Gorilla Trekking

Understanding the Weather in Gorilla Country

Mountain gorillas live high up. Bwindi Impenetrable National Park ranges from about 1,160 to 2,600 metres, while Mgahinga and Rwanda’s Volcanoes National Park climb higher still, onto the slopes of the Virunga volcanoes. At that altitude the air stays cool. Daytime temperatures usually sit between about 10°C and 23°C, and early mornings can feel cold, especially in Rwanda.

These are rainforests, so rain can fall in any month, often as a heavy afternoon shower that clears within an hour or two. What changes through the year is how often it rains and how long the trails take to dry out. That is why seasons matter more for comfort than for your chances of seeing gorillas.

June to September: The Long Dry Season

This is the most popular time for gorilla trekking in Uganda and Rwanda. Rainfall is at its lowest, the paths are firmer underfoot and the steep sections are less slippery. Clearer skies also mean better views across the forested ridges and, in the Virungas, of the volcano peaks themselves.

The catch is demand. July and August line up with school holidays in Europe and North America, so permits and the best-located lodges sell out early. If you want these months, plan at least three to six months ahead.

December to February: The Short Dry Season

The second dry window is warm, fairly dry and beautifully green after the November rains. It is a favourite for travellers who want to spend Christmas or New Year in Uganda or Rwanda. Expect lodges near Bwindi and Volcanoes to fill up fast around the holidays, and note that short showers can still arrive, especially in early December.

March to May: The Long Rains

This is the wettest part of the year, with April usually the heaviest month. Trails turn muddy and some slopes become hard work, so good boots and a walking stick matter more than ever. Our gorilla trekking packing list covers exactly what to bring. Roads into the parks can also be slower.

In return you get quiet forest, calm lodges and lush scenery, and many lodges offer lower rates in these months. Gorillas often feed lower down when food is plentiful, which can shorten a trek, although no guide can promise how far a family will be on any given day.

October to November: The Short Rains

The short rains tend to arrive in bursts rather than settling in for days. Mornings are often dry, with showers later in the day. For many travellers this is a good middle ground: fewer people than the peak months, but not the persistent rain of April. It is also a rewarding time for birders, because migrant species arrive from the north.

Best Time for Gorilla Trekking by Country

Uganda, Rwanda and the Democratic Republic of Congo share the same broad pattern of two dry and two wet seasons. The differences come from altitude, access and how each country fits into your wider trip.

Best Time for Gorilla Trekking in Uganda

Uganda is home to roughly half of the world’s mountain gorillas, spread across Bwindi Impenetrable National Park and Mgahinga Gorilla National Park. Bwindi is lower and slightly warmer than the Virunga parks, but its hills are steep and thickly forested, so dry-season trekking is noticeably easier on the legs. June to September and December to February are the most comfortable months.

Bwindi has four trekking sectors: Buhoma, Ruhija, Rushaga and Nkuringo. In the rainy months, Buhoma’s better road access can make it the more practical choice, while Rushaga in the south is closest to Kigali and Lake Bunyonyi. Uganda is also the only country offering the Gorilla Habituation Experience, which gives you around four hours with a family that is still being habituated. It runs all year, but permits are very limited, so book early whatever the season.

Best Time for Gorilla Trekking in Rwanda

Volcanoes National Park sits high on the slopes of the Virunga range, so it is cooler and often mistier than Bwindi. The dry months of June to September and December to February give the clearest views of the volcanoes and the firmest paths through the bamboo and nettle zones.

Rwanda’s big advantage is distance. The park headquarters at Kinigi is only about two to three hours’ drive from Kigali, so even a wet-season trek is easy to fit into a short trip. Rwanda’s permit costs considerably more than Uganda’s, which is one reason many travellers fly into Kigali and cross into southern Bwindi instead.

Best Time for Gorilla Trekking in DR Congo

Congo’s Virunga National Park follows the same seasonal pattern as Rwanda, with drier conditions from June to September and December to February. Kahuzi-Biega National Park, further south, is home to eastern lowland gorillas, a different subspecies from the mountain gorillas of Uganda and Rwanda.

For Congo, the security situation matters more than the weather. Parks can close at short notice, so check the latest advice before booking, and travel only with an operator who is in daily contact with the park authorities.

When to Book Your Gorilla Trek

Whatever month you choose, the permit is what decides your dates. Each habituated gorilla family can receive only eight visitors a day, so permits sell out before lodges do. For the dry months, book six months or more ahead. For the wet months, three months is usually enough, although last-minute permits sometimes come up. Permit rates are set by the Uganda Wildlife Authority and its counterparts in Rwanda and Congo, and they change from time to time. Our guide to booking gorilla permits explains how it works.

Plan Your Trek with Roots

So, which season is right for you? If you want firmer trails, choose the dry months and book early. If you prefer quiet forest and lower lodge rates, the wet months are a great choice. Either way, tell us your dates and interests, and we will check permit availability for you. Then we will build a free tailor-made itinerary around your trek.
