Rain defines the rhythm of equatorial life. In Uganda, Rwanda, and eastern DRC, gorilla trekking regions experience two primary rainy seasons: March to May and October to November.
During these periods, forests receive short, heavy bursts of rainfall, often in the early morning or late afternoon, followed by hours of stillness.
Despite this predictable pattern, the belief persists that gorilla trekking cannot happen during the rainy season.
Some consider it a logistical gamble. Others worry about visibility, trail access, or simply whether the gorillas will be out at all. You may have asked yourself the same: Is it even worth going during the wet months?
This article separates speculation from operational truth. It lays out exactly what to expect if you decide to go gorilla trekking in the rainy season, based not on hearsay, but on real field knowledge from East and Central Africa’s protected mountain parks.

Understanding the Rainy Season in Gorilla Trekking Habitats
Rainy seasons in East and Central Africa follow a dual pattern.
In Uganda and Rwanda, long rains fall between March and May, while short rains arrive from late September through November.
In the Democratic Republic of Congo, Virunga National Park observes a similar cycle, though patterns shift slightly in southern zones near Kahuzi-Biega.
These rainy months bring short, often intense showers. They typically occur in the early hours or late afternoon, with dry intervals in between.
Most forest trails remain navigable during daylight, especially when treks begin in the morning.
Mountain gorillas live in montane and submontane forests, where elevation influences rainfall. Bwindi Impenetrable National Park, for instance, sits between 1,160 and 2,600 meters above sea level.
The higher the altitude, the more moisture the vegetation holds. You will feel it almost instantly when you enter.
Myth vs. Reality – Gorilla Trekking in the Rain
“You can’t go gorilla trekking during the rainy season.”
This assumption is false and widespread.
Gorilla trekking is conducted year-round in all three countries where permits are issued: Uganda, Rwanda, and the Democratic Republic of Congo.
In Uganda, the Uganda Wildlife Authority maintains operations in Bwindi Impenetrable and Mgahinga Gorilla National Parks without seasonal closure.
The Rwanda Development Board does the same in Volcanoes National Park. In DRC, the Institut Congolais pour la Conservation de la Nature manages open access to gorilla trekking permits throughout the calendar year, including peak rainfall months.
Trekking schedules are unaffected by rain forecasts. Rangers meet early each morning to assess weather, assign gorilla families, and match tourists to trails based on fitness and interest.
If it rains overnight or during the trek, guides adjust timing and routes on the ground, but they do not cancel the activity.
Besides, the infrastructure is prepared. Paths are monitored and cleared regularly, and guides carry radios to coordinate route decisions with on-the-ground teams.
There are ponchos available for hire at park entrances, and waterproofing recommendations are included in pre-trek briefings.
So yes, you can, and thousands do.
“You won’t see gorillas if it’s raining.”
Gorilla behaviour does not follow tourism logic. These primates are not discouraged by rainfall.
They do not retreat into hidden shelters or disappear into the forest when it rains. They remain within their defined home ranges year-round, rain or shine.
Trackers who follow gorilla groups from dawn are often in contact with the apes well before the tourist groups depart.
Because trackers stay close to known nests, dung trails, and feeding sites, they report movements to park headquarters in real time.
In the rainy season, gorillas tend to forage at slightly lower altitudes, where secondary vegetation is richer and easier to feed on.
This means they are sometimes closer to park boundaries and accessible within shorter trekking distances.
It is not uncommon for tourists trekking in April or October to find their assigned gorilla group within an hour.
And when it rains lightly during the trek, gorillas often huddle in family clusters or feed under vines and forest canopy, perfect conditions for unobstructed photography.
If your concern is visibility, rest assured: the rain may wet your sleeves, but it rarely hides the gorillas.
“Treks are always longer during the rainy season.”
This is a half-truth that often leads to confusion. The duration of a gorilla trek depends on more than just rainfall. It depends on which group you’re assigned to, how far they’ve moved, and the altitude at which they nest that morning.
While it’s true that some trails get muddy or slippery during wet months, this doesn’t always translate into longer treks.
On the contrary, gorilla groups during the rainy season sometimes stay near trail-accessible feeding zones due to cooler temperatures and denser edible vegetation.
Each morning, the ranger team assesses gorilla movement data from the previous day and assigns groups accordingly.
If mobility is a concern, guides will allocate guests to a nearby family. There are over 20 habituated groups in Bwindi, 12 in Volcanoes National Park, and several in Virunga and Kahuzi-Biega.
Options allow for flexibility, even during challenging weather.
Moreover, park management makes accommodations. Porters are readily available. Walking sticks are handed out. Rangers choose accessible routes and pace the group based on comfort.
So while the trail may slow your steps, it doesn’t mean the experience will be longer or harder than expected.
“The experience is less enjoyable when it rains.”
Enjoyment is subjective. But if you measure value by solitude, photo quality, and environmental intensity, the rainy season has its own merits.
Fewer tourists visit parks during wet months, meaning groups are smaller and quieter.
Bird calls are sharper. Trails feel more isolated. And forest colours turn from muted greens to deep, saturated hues.
Photography during and after light rainfall can produce beautiful results.
Leaves glisten. Fog hangs in the canopy. The contrast of black fur against bright foliage becomes visually dramatic.
Many professional photographers time their visits for these conditions.
Yes, conditions are slippery. Your boots will sink slightly. You might crouch more often to avoid dripping vines. But what you get in return is a sensory experience few dry-season tourists receive.
If you’re someone who prefers comfort above all, you may find the rain inconvenient. But if you’re someone who finds meaning in raw nature, mud and all, the rainy season might surprise you.
Key Challenges of Gorilla Trekking in the Rainy Season
1. Slippery and Eroded Trails
Rainwater softens forest soil quickly, particularly in sloped areas.
In Bwindi and Mgahinga, footpaths become slick with clay, roots, and leaf litter after only 20 minutes of rain. This makes descent more difficult than ascent, especially on steep inclines or narrow bends.
Trail erosion is common during April and October. Guides adapt by choosing routes with better grip or using ranger-maintained bypasses.
You will be given a walking stick at the start of the trek; don’t underestimate its usefulness.
2. Gear Vulnerability to Water Ingress
Even waterproof gear reaches its limits after prolonged exposure.
Rain jackets work well in light showers, but constant downpour during ascent can soak through seams and zippers. Boots, even high-ankle designs, may fill with runoff on steep slopes.
Plastic backpack liners or heavy-duty rain covers are necessary to protect essentials like passports, permits, and electronics.
Some tourists carry extra socks sealed in freezer bags. These small precautions make a difference mid-way through a five-hour hike.
3. Delayed Departures and Extended Waiting
Heavy morning rainfall may delay departure from the trailhead as rangers reassess route conditions.
While rare, it happens. You may wait 30 to 60 minutes for updates before receiving a go-ahead from the briefing centre.
Moreover, gorillas sometimes move during the delay, which requires rerouting trackers and tourists in real time. Patience is essential on these days. (The forest keeps its own schedule.)
4. Increased Physical Demand
Trekking in the rainy season isn’t necessarily longer, but it’s certainly more tiring.
The forest becomes heavier with moisture. Clothes cling. Steps sink deeper into the mud. And air pressure at higher altitudes becomes more noticeable when humidity spikes.
Hydration is important, even when it’s cool. You’ll sweat under your rain gear, and altitude may exaggerate fatigue. Guides are trained to read body language and adjust pace as needed, but let them know how you feel at intervals.
Advantages of Gorilla Trekking in the Rainy Season
a. Greater Permit Availability and Flexibility
Rainy season months often experience reduced booking pressure.
In Uganda and Rwanda, permits remain available closer to the travel date, offering planners more flexibility.
In Uganda specifically, April, May, and November are categorised as “off-season,” and discounts may apply through local operators in collaboration with Uganda Wildlife Authority.
Tourists who struggle to secure permits in July or August often find April or October a viable alternative, with the same access to habituated groups and daily treks.
b. Smaller Trekking Groups and Quieter Parks
Daily treks are limited to eight visitors per gorilla group, but in the low season, groups often depart with five or fewer.
This creates a quieter experience, especially in entry zones like Ruhija, Rushaga, or Bukima.
Besides enhancing the acoustic environment of the forest, smaller group sizes give you more flexibility during the one-hour viewing window.
You’re not rushed by others and can maintain your observation rhythm.
c. Shorter Trekking Distances Are Sometimes More Likely
During rainy months, mountain gorillas often stay closer to feeding areas at lower altitudes.
Rain softens young shoots and wild celery, which are easier to access near forest edges.
Rangers note that in April and October, groups like Mubare (in Buhoma) and Amahoro (in Rwanda) are regularly located within a 90-minute walk of the trailhead.
While not guaranteed, the likelihood of shorter treks does increase. For some, that alone justifies the timing.
d. Photographic Richness and Atmospheric Conditions
Rain amplifies visual contrast in montane forests.
Dark trunks stand out against bright moss, and moisture deepens colour tones across undergrowth.
Mist sometimes hangs in the canopy for hours after a light shower, adding atmospheric quality to wide shots and portraits.
If you’re travelling with a camera or even a good phone, expect richer light diffusion, softer shadows, and naturally reflective surfaces.
Essential Gear for Rainy Season Treks
Wet-season gorilla trekking requires just a few gear adjustments, but they make all the difference once you’re on the trail.
The items below are considered essential for comfort and mobility in Uganda, Rwanda, or the DRC during the rainy months.
- Waterproof hiking boots
Trails turn slick after short rain bursts. High-ankle boots with solid grip help prevent slipping and protect your feet from pooling water.
- Rain jacket with hood
Choose a breathable, seam-sealed jacket. Ponchos work too, but strong winds in higher zones make a fitted jacket more reliable. - Backpack rain cover
Waterproof covers shield electronics, snacks, and personal items. In some parks, mist alone is enough to soak an uncovered pack. - Gaiters
These prevent mud, ants, and thorns from entering your boots. They also reduce sock saturation during long downhill walks. - Gardening or trekking gloves
You’ll use your hands more than expected, grabbing vines or balancing on rocks. Gloves protect your grip and skin, especially in wet undergrowth. - Walking stick or trekking poles
Even short trails become more technical in the rain. Guides provide wooden sticks, but collapsible trekking poles give better control if you’re familiar with them.
Conclusion: Who Should Consider Rainy Season Treks
Not every tourist should trek in the rainy season, but for some, it’s an ideal time. The groups below benefit the most from wet-season planning.
- Photographers and filmmakers
Rain heightens the forest atmosphere. Moisture sharpens contrast. Mist hangs longer in the upper canopy. For close-range primate photography, April and October can be visually exceptional. - Budget-conscious travellers
April, May, and November often come with seasonal permit discounts in Uganda. Tour operators may also offer lower rates on accommodation and transfers. - Repeat visitors or second-time trekkers.
Those returning for another gorilla experience often value intimacy over comfort. Rainy season treks feel slower, quieter, and less structured. That appeals to the experienced. - People seeking quieter forests
Fewer tourists visit during the rainy months. Briefing centres are calm. You may trek in a group of four or fewer. It changes the feel entirely. - Physically fit hikers who enjoy a challenge
Steep inclines, soft ground, and cooler temperatures make the trek more physically demanding. For fit hikers, this can add purpose rather than difficulty.
If any of these sound like you, or a client you’re advising, then a rainy season trek might be a smart and deeply memorable choice.
