March to May and October to November are the ‘green season’. Yes, it rains — usually a heavy burst, not all day — and the trails are muddier.
In exchange: permits are available at short notice, lodges drop their rates, the forest is loud with birds, and you may have the family to yourselves. If you’re fit and flexible, it’s the smart time to come.
Uganda’s other primate permit costs USD 60 and rarely sells out. The troop lives in the bamboo zone on the lower slopes of the Virungas, and a visit is usually a gentle 1–2 hour walk.
They move fast and constantly, so it’s a different kind of hour to the gorillas — less awe, more delight. Pair it with the Mgahinga gorilla family or a Sabinyo climb and you have a full, uncrowded day.
The nine that matter: broken-in waterproof boots, gaiters or long thick socks, garden gloves for nettles and vines, a rain jacket that actually works, long trousers and sleeves, 2 litres of water, energy snacks, a dry bag for the camera, and a walking pole.
Wear neutral colours. Leave the umbrella, the heavy tripod, the new boots and the cotton hoodie. Everything else your porter can carry — and you should hire one.
Rwanda’s permit is USD 1,500; Uganda’s is USD 800. Rwanda’s trailhead is 2 hours from Kigali airport on tarmac; Uganda’s Bwindi is a long drive or a light-aircraft hop.
Rwanda’s Volcanoes NP is open bamboo and potato fields on a volcano’s flank — photogenic, often muddy, sometimes high. Bwindi is true rainforest: darker, denser, more of a scramble.
The best trips do both, back to back — one trek in each, crossing at Cyanika. See our Uganda–Rwanda combo.
Bwindi has more gorilla families, more trekking sectors and the higher success rate — but thicker forest and steeper ground. Nkuringo and Rushaga in the south are the toughest and quietest; Buhoma in the north is the most developed and the easiest to reach.
Mgahinga is a single habituated family, more open walking, often a shorter day, and far fewer people. The catch: the family occasionally crosses the border into Rwanda, and treks are suspended until it comes back.
If it’s your only gorilla trek and you want the surest thing, pick a Bwindi sector matched to your fitness. If you’re also doing golden monkeys or climbing a volcano, Mgahinga earns its place.
The briefing is short. A ranger reads out the rules — seven metres, no flash, no eating in sight of the group, one hour — splits everyone into eights, and then you’re walking.
The first hour is a farm track. It’s easy, and it tricks people. Then the track ends at a wall of green and the guide takes a machete off his back. From there it is hands-and-feet steep, wet underfoot, and slow.
Then the radio crackles, the guide stops, and says: packs down, cameras out.
The trackers have been with the family since first light. You close the last hundred metres quietly and they are just there — a blackback stripping bark, juveniles wrestling down a slope, the silverback watching you with complete indifference.
The hour goes fast. On the walk out nobody talks much. Back at the trailhead there is a certificate, a warm soda, and porters singing while they wait for the next group. Most people are already asking when they can do it again.
