gorilla trekking jet lag is one of Africa’s most extraordinary wildlife experiences, connecting travellers with mountain gorillas in their natural forest habitat. The best way to stop jet lag spoiling your gorilla trek is to leave at least two full days between landing in Uganda and trekking. That usually means a night in Entebbe, a travel day to Bwindi and a night at your lodge, so you trek on your third morning or later. Uganda is on East Africa Time (UTC+3), seven to eight hours ahead of New York and two to three hours ahead of London, so travellers from the Americas and Asia-Pacific feel it most. Morning daylight, steady meals and sensible sleep timing help your body clock catch up.
Gorilla trekking and jet lag: managing long-haul fatigue on your trek day
Why jet lag matters on trek day
The briefing starts at about 7:30 am, and treks last anywhere from two to eight hours in total, including the hour with the gorillas. The slopes are steep, muddy and at 1,500–2,600 m, and you need concentration to keep your footing. If your body still thinks it is the middle of the night, everything feels harder. A gorilla permit costs US$800 (US$600 in April, May and November) and is issued for a fixed date, so it is worth planning the trip around arriving fresh.
How big is the time difference?
Uganda does not change its clocks, so the gap depends on the season where you live. It is two hours ahead of London in summer and three in winter, and one or two hours ahead of most of continental Europe. From New York and Toronto it is seven hours ahead in summer and eight in winter; from Los Angeles, ten or eleven. Travellers from Australia go the other way: Uganda is seven hours behind Sydney, or eight during Australian daylight saving.
Europeans therefore have little jet lag, while North Americans and Australians face a bigger shift. Our guides for travellers from Toronto and Sydney cover the routes.
Plan buffer days
Most well-planned itineraries already include buffer time, because Bwindi is 8–10 hours by road from Entebbe or a short domestic flight away. A common pattern is to land in Entebbe and stay near the airport, travel to Bwindi the next day, and trek the morning after. Coming from the Americas or Australia, an extra night, perhaps at Lake Mburo or Lake Bunyonyi on the way, or a few days in Kibale and Queen Elizabeth first, puts the gorillas later in the trip when you are fully adjusted. Avoid booking the trek for the morning after a late-night arrival.
On the flight
Set your watch to Uganda time when you board, and try to sleep when it is night in Uganda rather than at home. Eye mask, earplugs or noise-cancelling headphones and a neck pillow make sleep more likely. Drink plenty of water and go easy on alcohol and caffeine, which both disrupt sleep. Some travellers use melatonin, taken at bedtime in the new time zone, to help shift the body clock; ask your doctor whether it suits you. Avoid sleeping pills you have not tried before.
Your first days in Uganda
Daylight is the strongest signal for resetting your body clock. If you have travelled east from the Americas, get outside in the morning, with breakfast on a terrace, a walk by Lake Victoria or the Entebbe Botanical Gardens, and avoid bright light late at night. Eat meals at local times, even if you are not hungry, and keep naps short, no more than 20–30 minutes in the early afternoon. Go to bed at a normal local time; Uganda is on the equator, so it gets dark around 7 pm all year.
Gentle exercise helps too. A short walk on arrival day and an easy afternoon nature or village walk at your lodge the day before the trek loosen your legs after the flight without tiring you out.
The night before and on trek day
Pack your daypack, lay out boots and clothes, charge your camera and arrange your wake-up call the evening before, so the early start is easy. Eat a proper dinner, drink water and skip the extra drinks at the bar. In the morning, have a good breakfast and take snacks and at least two litres of water.
Hire a porter to carry your bag; it makes a real difference when you are tired. If you feel unwell rather than just tired, tell the ranger at the briefing. Our health preparation timeline and fitness guide cover the rest of your preparation.
Frequently asked questions
At least two full days, so you trek on your third morning or later. Travellers from the Americas or Australia benefit from an extra day.
East Africa Time, UTC+3, all year, with no daylight saving.
It can be, as Uganda is seven to eleven hours ahead of the US depending on the coast and season. Buffer days and morning daylight help most.
Rarely. Bwindi is a full day from Entebbe by road, and trekking straight after a long flight is hard work.
