How hard is gorilla trekking, really?

Uganda Wildlife Authority states that a gorilla trek can last between two and seven hours, and describes the fitness required as moderate. The hard part is not the distance but the ground: steep, wet, trackless forest at altitude, walked at the trackers' pace, with no fixed turnaround point, because you keep going until the group is found.

It is the only walk on a safari itinerary where nobody can tell you in advance how long it will be.

How long does a gorilla trek take?

Uganda Wildlife Authority gives a range of two to seven hours for tracking in Bwindi, and says tracking can last from a few hours to a whole day depending on how far the gorillas have moved overnight. There is no published equivalent range from the Rwanda Development Board for Volcanoes National Park.

Under UWA's 2024 Guidelines for the Management of Gorilla and Chimpanzee Tracking, tracking time runs from immediately after the morning briefing until you return for debriefing. Gorilla tracking starts from 8:00am; the Gorilla Habituation Experience starts from 6:30am. In Rwanda, RDB's booking guidelines set a 07h00 reporting time for Volcanoes National Park.

Once you reach the gorillas, the viewing window is fixed and short. UWA allows a maximum of one hour, timed from the moment you reach them; the Gorilla Habituation Experience allows a maximum of four. Visit Rwanda states a strict maximum of one hour per day per group. So the variable part of the day is entirely the walking.

Plan the whole day for it: no afternoon flight, no long transfer, no second activity.

What actually makes it hard?

Six things, roughly in the order people underestimate them.

• The ground. There is often no path. Guides cut a line through vegetation, and the surface underneath is root, mud and slope rather than trail. Distance covered is small; effort per kilometre is not.
• Gradient. Bwindi and the Virungas are steep in both directions, and coming down a wet slope is harder on the knees than going up it is on the lungs.
• Altitude. The Institute of Tropical Forest Conservation's long-term weather station at Ruhija in Bwindi sits at 2,400 metres, and Volcanoes National Park spans roughly 2,400 to 4,507 metres. Bwindi's other trailheads are lower, and no authority publishes a park-wide trekking altitude. Neither is extreme altitude, but it is enough that a climb feels heavier than it would at home, especially in your first day or two.
• Mud and rain. The ITFC record for Ruhija shows rainfall peaking March to May and September to November, with dry troughs in December to January and June to July. June, July and August were the driest months in every year of that 13-year record. But the same record notes heavy rain in July 1988 — a dry-season month is a probability, not a promise.
• Cold. Also from Ruhija: a mean daily maximum of 19C and a mean daily minimum of 14C, with recorded extremes of 11C to 24C, and June and July the coldest months. That is colder than equatorial Africa sounds. Our gorilla trek packing list covers the layers properly.
• No refuelling. UWA's tracking rules state no smoking, eating or drinking during the tracking. Eat a real breakfast, and take your guide's instruction on the day about where and when a break is allowed.

What does not make it hard: pace. You move at the speed of the slowest person in a group of eight, and the trackers ahead set the route.

Is Uganda or Rwanda physically easier?

No authority publishes a difficulty rating for either, so treat confident rankings with suspicion. What can be compared is published detail.

Neither is reliably the easier trek, because in both countries the deciding factor is where the gorillas happen to be that morning. Operators will tell you Rwanda's volcanic slopes are more open and Uganda's forest denser; that is operator observation, not published policy. The wider comparison — cost, access, feel — is in our piece on Uganda versus Rwanda for gorilla trekking.

Can you book an easier trek?

Not directly, and this is the most misunderstood point in gorilla trekking. UWA's 2024 guidelines are explicit that permits are booked by date and by designated entry point, and that visitors are allocated to a gorilla family on the morning of tracking. Nobody can sell you a named family or a guaranteed gentle day, because that allocation does not exist until the briefing.

What you can influence:

• The entry point. Uganda's designated trailheads are Buhoma, Ruhija, Nkuringo and Rushaga in Bwindi Impenetrable Forest, and Ntebeko in Mgahinga. Operators hold views on which trailheads sit on gentler ground; that is operator knowledge, not published policy, and the family you are given still decides the day.
• What you say at the briefing. If you have a knee, a hip, a heart condition or simply a realistic view of your limits, say so there rather than assuming it was noted at booking. Whether it changes your allocation is at the warden's discretion — no UWA guideline promises it.
• The month. You cannot choose the terrain, but you can choose whether it is likely to be wet. Note the trade-off in April, May and November: UWA's low-season months, when a foreign non-resident permit is USD 600 rather than USD 800, sit inside the wetter parts of the ITFC rainfall record, and UWA states low-season permits cannot be rescheduled.

What help is available on the mountain?

Hire a porter. Not as a courtesy — as fitness strategy. Visit Rwanda states that porters are available to carry backpacks and cameras as well as to offer a helping hand along the route, and that helping hand on a wet descent is worth more than the carrying. In Uganda, no gorilla-trekking porter fee appears in the UWA Conservation Tariff, so there is no official rate to quote in advance. We confirm the going rate when we quote and make sure you have small notes for it.

For travellers with limited mobility, Rwanda publishes a position: Volcanoes National Park staff will provide a strong arm to lean on, or a stretcher for those confined to a wheelchair, arranged by contacting the park directly. No price is published for it.

Uganda has no equivalent published product. The carried chair that operator sites advertise appears in no UWA tariff and no UWA guideline. We check case by case what can actually be arranged before anyone books a trip around it, and we will tell you if the answer is no.

What could stop you trekking on the day?

Two rules matter more than fitness, and both are absolute.

Age. The minimum is 15 in Uganda (UWA guidelines) and 15 in Rwanda (RDB guidelines). There is no discretion in it.

Illness. UWA's rules state that you must not visit the gorillas with a cold or other infectious illness, because they catch human respiratory infections. A visitor showing signs of illness before tracking is not allowed to go, is referred to the nearest health facility, and bears the cost of diagnosis and treatment. Where that happens to a visitor already in the park, UWA's guidelines provide a refund of 50% of the permit value, less incidental costs, authorised by the Executive Director. The same 50% applies to a client who cannot track because of an accident sustained in the park.

If you track a full day and the gorillas are not found, UWA's guidelines allow the Executive Director to authorise rescheduling to the following day; where no slots exist or the itinerary does not allow it, the permit may be cancelled with a 60% refund, certified by the Chief Warden and less incidental costs. The discounted low-season permit — USD 600 in April, May and November, against USD 800 the rest of the year — cannot be rescheduled at all.

We are not a medical service. Take any question about your heart, lungs, joints, altitude or medication to a travel clinic or your own doctor well before you book, and to official government travel-health guidance for your country.

How should you prepare in the months before?

The training that works is specific and boring. Walk hills, with a daypack on, for an hour or more, once or twice a week for the two months before you travel. Add stairs if you have no hills. Descend as often as you climb, because the descent is what hurts. Wear the boots you will trek in until they are genuinely broken in — new boots on a wet Bwindi slope are a classic self-inflicted injury.

Two things to be realistic about. The Gorilla Habituation Experience is a harder day than a standard trek: a 6:30am start and up to four hours with the gorillas on top of the walking, at USD 1,500 per foreign non-resident, rising to USD 1,800 on 1 January 2027. Book it only if your hill fitness is genuinely good. If a full gorilla day looks like too much, chimpanzee tracking is a different proposition — UWA gives treks from Kanyanchu in Kibale Forest as lasting two to five hours, in groups capped at six, at USD 250 for a foreign non-resident, USD 200 in April, May and November, and USD 300 from 1 January 2027. Our chimpanzee tracking page sets out how it differs.

The short version

If you can walk uphill for two hours, in the rain, without needing to stop every ten minutes, you should manage the walking comfortably. If you cannot, you may still be fine — but tell us before we buy the permit rather than on the morning of the trek, because a permit paid in full is not easily undone. UWA suspended its seven-day reservation window on 1 March 2026, so there is no free hold: a permit is secured only on full payment at booking, and a foreign non-resident cannot buy one directly — a Uganda Tourism Board licensed operator has to. Our guide to Uganda gorilla permit costs and booking covers that.

Our gorilla trekking page sets out how we run a trekking day, and the Bwindi gorilla short break shows how a trekking day sits inside an itinerary. When you are ready to talk specifics — including honestly about fitness — start your safari plan. What you tell us changes what we recommend.
