The best time to book a gorilla trek in Uganda

Gorillas don't keep a season

The habituated families in Bwindi Impenetrable National Park and Mgahinga Gorilla National Park live there every month of the year. There is no migration to time and no breeding window to chase.

Trackers head into the forest ahead of each group in the wet months as much as the dry ones. So the question is not whether gorillas are around in your month. It is how hard the walk will feel, and whether a permit is still free for your date.

The two drier spells

Southwest Uganda has two drier periods, roughly June to August and December to February. Paths dry out a little in those weeks, and your boots grip better on the steep sections.

These are also the weeks most travelers want. Each family takes at most 8 visitors a day, so permits for the drier months go first. Our guide to the $800 permit explains how operators reserve one in your name.

Drier does not mean dry. Bwindi is a rainforest, and a heavy shower can roll in on any afternoon, so a rain jacket belongs in your bag whatever the date says.

Trekking through the rains

The wetter spells run roughly March to May and September to November. Treks go ahead as normal in those months, and the early morning briefing at the park office happens whatever the sky is doing.

The price is paid underfoot. Slopes turn slick, mud can reach your ankles, and the same climb takes more effort and more care on the way down. If you doubt your knees, read how hard the trek can be before picking a wet month.

The rains have upsides too. Some operators and lodges lower their rates in the wetter months, and permits are easier to find at shorter notice. None of our five listings shows a fixed seasonal discount, so ask the operator directly.

Cool mornings at altitude

Bwindi spans roughly 1,160–2,600 meters (3,800–8,500 feet), so it is cooler than most people expect so close to the equator. Temperatures sit around 7–20 °C (45–68 °F), depending on height and time of day.

Mornings at the park office can call for a fleece, and you warm up fast once the climb begins. Mgahinga, on the slopes of the Virunga volcanoes, lies higher and more open, as our Bwindi or Mgahinga comparison explains.

How timing plays out on a three-day trip

Eco Adventure Safaris' 3-day trek at ~$1,860 shows why dates matter. The $800 gorilla permit is part of that price, so the operator must secure a permit for your day before the trip can go ahead.

It holds 5.0 from 74 reviews on Viator and includes a private air-conditioned vehicle plus all fees and taxes, with a Batwa experience added. What counts against it: it follows the same shape as our pick for less money with less evidence behind it, and GetYourGuide does not sell it.

If that trip is full for your week, Dav Safaris' 3-day trek at ~$2,600, our pick, runs a similar plan and holds 5.0 from 200+ reviews on Viator. Our page on what a gorilla trek costs compares all five prices.

Timing a longer trip

A trip that adds chimpanzees in Kibale Forest National Park needs the same thinking about weather. Kibale is rainforest too, so wet weeks bring slippery paths there as well as in Bwindi.

The two longer tours that do both are set side by side on our gorillas and chimps in one trip page. Their chimpanzee permits are limited as well, so the same advice applies, and the busy weeks fill first.

The habituation experience in Bwindi has far fewer permits per day than the standard trek. If you want those four hours with a family, settle the date before anything else, as our habituation guide explains.

Road time matters in the rains as well. The drive from Entebbe to Bwindi is a long day on dry roads, and wet stretches can slow it further, so leave slack in the plan rather than stacking flights on the last afternoon.

When we would skip

We would think twice about the wettest weeks if you have a weak knee or little hiking behind you. The walk can be long in any month, and mud adds strain going down as well as up.

We would also skip a last-minute plan for July or January. Without a permit there is no trek, and even Kawira Safaris' day trip from Kigali at ~$400 needs the $800 permit and a Uganda visa on top, both sorted in advance.

A trek the morning after a long-haul flight is a third thing we would avoid. A spare day before the forest lets you recover from the journey and get used to the altitude.

The date that works for you

The right time to go is the week you can get a permit and a few free days. With a choice, the drier spells give easier footing. Without one, the rains do not stop treks from running.

Book as soon as your dates are fixed, then pack for wet weather anyway. Our packing list for the forest covers boots and gloves, and the rules for your hour with the family stay the same in every month.
