The best time for chimpanzee trekking in Rwanda is during the dry seasons: June to September and December to February. Nyungwe Forest National Park, where all chimpanzee trekking takes place, is open year-round, but dry-season trail conditions produce firmer, more manageable paths and allow rangers to locate the habituated communities more efficiently near water sources. Chimpanzee permits cost $150 per person for foreign non-residents in 2026 and are available daily from the Rwanda Development Board, though dry-season permits sell out months in advance.
Rwanda experiences two distinct wet seasons: the long rains from March to May and the short rains from October to November. Both wet periods bring significant rainfall to Nyungwe’s high-altitude montane forest, leading to slippery trails, river crossings that become more difficult, and mud conditions that slow trekking considerably. That said, chimpanzee trekking does not stop in the wet season, and the period has specific advantages including more abundant fruit in the forest, which can concentrate chimpanzees closer to the trails and reduce search time. Permit availability during wet season months is considerably better, and lodge rates are often lower.
Best overall period. Trails are dry and navigable. Chimps move toward water sources, making location more predictable. Peak visitor demand — permits often sell out 6 to 12 months in advance. Most comfortable trekking conditions.
Second dry window. Good trail conditions. Slightly fewer visitors than June to September outside the Christmas and New Year period. A strong alternative for those who cannot travel in the peak months.
Long rains. Trails become muddy and steep sections more challenging. Food abundance in the forest may bring chimps closer to the trail network, reducing trek duration. Permits more available. Lower accommodation rates.
Short rains. Similar conditions to March to May. Migratory birds arrive, making this a strong period for birders combining trekking with Nyungwe’s avian diversity. Fewer trekkers than dry season.
Best Time for Chimpanzee Trekking in Rwanda: The Dry Season Advantage
During the dry season months of June to September, Nyungwe Forest National Park receives less rainfall and the trail network dries out between sessions. The paths are firmer underfoot and steep sections, which account for a significant portion of the trekking route in both the Uwinka and Cyamudongo sectors, remain negotiable without the risk of falls on wet volcanic soil. Rangers report that during the dry season, chimpanzees concentrate around streams and other water sources within the forest, which are consistent locations that rangers track daily.
Photography conditions during the dry season are generally stronger than during the wet months. Lower humidity reduces the condensation on camera glass, and the thinner vegetation in the drier forest allows more light to penetrate the canopy, improving exposure options for forest photography. The reduced leaf density also improves sightlines when chimpanzees are in the middle and upper canopy, making it easier to see and photograph the animals clearly from ground level.
The primary disadvantage of the June to September window is demand. Chimpanzee permits in Nyungwe are limited to 24 per day across all habituated communities, and during the peak months this quota is frequently exhausted weeks or months in advance. Travelers planning dry-season chimpanzee trekking in Rwanda should book permits and accommodation six to twelve months ahead. Last-minute availability is rare for June, July, and August in particular.
Chimpanzee Trekking Rwanda in December to February
The December to February dry window is considered the second-best period for chimpanzee trekking. Trail conditions in Nyungwe during these months approach those of the June to September peak, with reduced rainfall and firmer paths. Temperatures in Nyungwe during December and February are slightly warmer than during the June to September peak, which reduces the need for heavy layering at early morning briefing times.
The Christmas and New Year period within this window — roughly 20 December to 5 January — is a high-demand period that should be booked as far in advance as any peak-season date. Outside of those specific dates, January and early February are generally easier for permit availability than the core June to September months, and accommodation rates in January may reflect low-season pricing at some lodges in the Nyungwe area. This window is a good choice for travelers from the Southern Hemisphere who travel over the Northern Hemisphere’s low season.
Wet Season Chimpanzee Trekking: March to May
Chimpanzee trekking in Nyungwe during the long wet season from March to May is a valid option for visitors with flexible travel dates or a tighter budget. The forest receives its highest rainfall during this period, and trails on steep slopes become slippery enough that walking poles are strongly recommended. River crossings within the park may be deeper than usual. However, the Rwanda Development Board does not close the trekking activities due to rain, and trekking proceeds on scheduled days unless conditions are unusually severe.
The key advantage of wet-season trekking is food abundance. Nyungwe’s forest produces significant quantities of fruit during the wet season, and the chimpanzees respond by feeding intensively in concentrated areas rather than ranging widely in search of food. Rangers frequently locate habituated communities more quickly during the wet months because the chimps remain in fruit-bearing tree zones rather than travelling across broad areas of the forest. Shorter search times in the wet season can mean the total trekking day is three to four hours rather than the five to six hours possible during dry-season searches.
Permit availability during March, April, and May is considerably easier than during dry-season months. The 24 daily permits across Nyungwe’s habituated communities are rarely fully subscribed in the wet months, which means bookings made two to four weeks in advance can usually be secured. Lodges in the Nyungwe area typically offer lower rates during the wet season, and some operators reduce package prices to reflect the lower demand. The forest scenery during the long rains is also at its most lush and colourful, which some visitors and photographers prefer for the atmosphere it creates.
October and November: Short Rains and Chimpanzee Trekking
The October to November short rain period shares most of the characteristics of March to May but is shorter in duration and typically less intense in total rainfall. October and November bring good conditions for combining chimpanzee trekking with the other activities Nyungwe Forest offers: migratory bird species arrive during this window, and the park’s 310 recorded species are supplemented by additional visitors from outside the region. The Great Blue Turaco, Rwenzori Batis, and several sunbird species are most visible during this period on the forest trails.
Permit availability in October and November is better than in the dry months but can be more constrained than March to May. Some travellers planning for October book two to three months in advance as a precaution, particularly for the Cyamudongo sector which is the more popular of the two chimpanzee trekking areas due to its shorter and more predictable trek durations. November permits are generally among the easier to secure in the annual cycle, as this is a transition period between short rains and the December to February dry window.
Month-by-Month Chimpanzee Trekking Conditions in Rwanda
January sits within the dry window and offers good trail conditions with slightly fewer visitors than June to September. February is dry with good conditions; wildlife including chimps is active. March marks the beginning of the long rains; trails begin to deteriorate and search times may shorten as food concentrates the chimps near the trails. April is the wettest month in most years; trekking continues but conditions are most challenging. May sees the tail end of the long rains, beginning to ease by the third week. June opens the peak dry season; permits fill quickly and conditions are at their best. July and August are the driest months and see the highest visitor volumes. September remains dry but begins to see the first signs of seasonal transition. October brings the short rains; conditions deteriorate quickly after heavy overnight rainfall but clear during the day. November continues the short rains with some easing by mid-month. December opens the second dry window from mid-month onwards, with early December still potentially wet.
Only 24 chimpanzee trekking permits are issued per day in Nyungwe Forest National Park across all habituated communities. For June, July, and August 2026 dates, booking should have begun no later than early 2026. If peak dates are already fully booked, consider the October to November window as the next best option for reasonably available permits without the full commitment of wet-season trekking conditions in April. The Rwanda Development Board website at rdb.rw shows live permit availability by date.
Getting to Nyungwe Forest National Park for Chimpanzee Trekking
Nyungwe Forest National Park is located approximately 225 kilometres southwest of Kigali. By road in a 4WD vehicle, the drive takes five to six hours along a paved route that passes through the towns of Butare and several highland communities before reaching the park at Gisakura. Road conditions are generally good on this route year-round, though the final approach to some lodges within the forest boundary involves steeper unpaved sections that can be challenging after heavy rain.
RwandAir operates domestic flights from Kigali International Airport to Kamembe Airport, which is approximately 50 kilometres from Gisakura, reducing transit to around one hour in the air. A transfer from Kamembe to Gisakura takes an additional 45 to 60 minutes by road. The domestic flight option is particularly useful for visitors combining chimpanzee trekking with gorilla trekking in Volcanoes National Park, as it eliminates the need to drive the full length of the country between the two parks. Kigali is a convenient midpoint between Volcanoes and Nyungwe for itineraries covering both parks.
Which months have the most available chimpanzee permits in Rwanda?
March, April, May, October, and November are the months when chimpanzee permits in Nyungwe Forest are most readily available, as these are the wet season months with lower overall visitor numbers. April is typically the easiest month for last-minute permit acquisition. Permits for June, July, and August are the most competitive and should be booked as far in advance as possible.
Is chimpanzee trekking cancelled during heavy rain in Rwanda?
Chimpanzee trekking in Nyungwe Forest is not cancelled due to rain under normal conditions. Rwanda’s habituated chimpanzee communities are active year-round and rangers conduct daily tracking regardless of weather. Heavy overnight rain that makes specific trail sections genuinely impassable may cause rangers to redirect the trekking group to an alternative route, but full cancellations are uncommon. Visitors should carry appropriate rain gear regardless of season.
How does the best time for chimpanzee trekking compare to gorilla trekking in Rwanda?
The optimal season for both chimpanzee and gorilla trekking in Rwanda is the same: the dry months of June to September and December to February. Both activities are located in highland rainforest environments where trail conditions improve significantly during the dry season. The key practical difference is permit scarcity: gorilla permits at $1,500 each are more heavily competitive than chimpanzee permits, and gorilla trekking bookings for peak months can be fully subscribed a year in advance.
Can I do chimpanzee trekking in April in Rwanda?
Yes. Chimpanzee trekking operates in April despite it being Nyungwe’s wettest month. Trail conditions are at their most challenging in April, with significant mud on steep sections and possible river crossings at higher water levels. Chimps are often found more quickly in April due to concentrated fruit feeding near the trails. Waterproof boots, trekking poles, a rain jacket, and full pack cover are all necessary for April trekking. Permits are easier to secure in April than any other month.
What time of day does chimpanzee trekking start in Rwanda?
Chimpanzee trekking in Nyungwe Forest departs from Uwinka or Gisakura Reception Centre from approximately 5:00 to 6:00 a.m. after a ranger briefing. This early start reflects the chimpanzee community’s pattern of peak activity in the morning hours and the need to find the group before they disperse widely through the forest during mid-morning. Visitors staying at lodges more than 30 minutes from the reception centre should plan pre-dawn departures and ensure their accommodation can provide an early breakfast or packed breakfast.
