The daypack you carry on your gorilla trek is a small but consequential decision. Too heavy and it becomes a burden on a potentially long, steep walk. Too light and you arrive at the gorilla family without the gear you needed. The ideal daypack for Bwindi is a well-organised 15 to 20 litre bag containing a specific set of items chosen for the conditions of the forest, the duration of the trek, and the particular physical and photographic demands of the encounter. This guide provides a detailed contents list based on the actual conditions of a Bwindi gorilla trek.
The pack itself: size and fit
A 15 to 20 litre daypack is the ideal size range. Smaller and you cannot fit all necessary items without awkward external attachment. Larger and the pack becomes heavier than necessary and potentially unwieldy on narrow forest trails. The pack should fit close to the body and distribute weight to the hip belt or waist strap — a bag that swings or bounces with every step increases fatigue significantly over a multi-hour hike.
Waterproof or water-resistant fabric is strongly advisable. Even in the dry season, forest humidity is high and unexpected rain showers occur. A pack liner — a waterproof dry bag that sits inside the main compartment — provides additional protection for electronics and paperwork. The camera section of the pack (if you carry a dedicated camera bag insert) should be padded on all sides.
Remember: if you hire a porter — which is strongly recommended — they carry your daypack. You walk with only a small waist or chest bag containing your camera, water bottle, and personal essentials accessible during the trek. The porter carries the heavier main pack. This halves the physical burden and allows the porter’s local knowledge and physical strength to manage the awkward terrain sections.
Water: the most important item
Carry two litres of clean drinking water at minimum. For longer treks (four hours or more anticipated), three litres. A hydration bladder with a drinking tube is more convenient than bottles on a long trek, as it allows drinking while walking without stopping to retrieve and replace a bottle. If using bottles, place them in side pockets for easy access without removing the pack.
The lodge will typically provide at least one bottle of water in your packed lunch. Count this against your total water allocation but bring your own supply rather than relying on it — some lodges are less consistent than others with packed lunch provision, and the last thing you want on a long trek is to run out of water before the observation hour begins.
Food: the packed lunch and supplements
Most lodges provide a packed lunch box, which should be confirmed with lodge staff the evening before the trek. In addition to whatever the lodge provides, carry: two to three bananas (potassium for muscle function, natural packaging, self-contained), a bag of roasted groundnuts (protein, fat, calorie density), two energy bars or equivalent, a small piece of dark chocolate (quick energy, morale), and any personal snacks that you know work well for you during physical exercise.
The total food weight should be minimal. You are not provisioning for a multi-day expedition — you need fuel for a single day of moderate to hard exercise with a rest period at the midpoint. Avoid heavy, water-rich foods that add weight without proportional caloric return.
Rain gear and layers
A waterproof jacket is essential regardless of season. The forest creates its own microclimate, and rain can arrive without warning even on clear mornings. The jacket must be genuinely waterproof (sealed seams, waterproof membrane) rather than merely water-resistant. A lightweight packable jacket that compresses into its own pocket works well — it adds minimal weight and volume when not needed and is immediately available when conditions change.
A light fleece or merino mid-layer is worth including for early morning starts and for the high-altitude sections of certain treks. Even in Uganda’s equatorial climate, Bwindi at 2,000+ metres can feel cold in the pre-dawn hours, and arriving at the briefing point in a single T-shirt on a cool morning is uncomfortable. The mid-layer packs small and can be removed and stowed in the pack once the exertion of the hike warms you.
First aid and personal health items
A compact personal first aid kit: blister plasters (the single most-used item), a small tube of antiseptic cream, antihistamine tablets (for insect sting or allergic reaction), ibuprofen or paracetamol, and a small bandage or gauze pad. This covers the realistic range of minor issues that arise on a forest hike. Do not over-pack the first aid kit — a full expedition medical kit is unnecessary and adds weight. If you have a specific medical condition that requires equipment (EpiPen, inhaler, blood pressure medication), carry it in an easily accessible front pocket.
Insect repellent: apply DEET-based repellent (minimum 30 percent DEET) to exposed skin before leaving the lodge. The forest environment has biting insects — not necessarily the major malaria risk that lower-altitude areas present, but mosquitoes, forest flies, and biting midges are present. A small bottle of repellent in the pack allows re-application after sweating removes the initial application.
Sunscreen: less critical in the dense forest canopy than on open terrain, but apply to face, neck, and any exposed skin before departure. The briefing point is typically in open terrain where sun exposure is meaningful.
Camera gear and accessories
Camera body and lens in a padded camera bag insert within the main pack. Spare battery — the most commonly forgotten item — fully charged the night before. Spare memory cards. Lens cleaning cloth and a small air blower for dust removal. UV filter on the lens provides physical protection without optical penalty. Consider a small tripod or monopod for the gorilla hour if you shoot with a heavy telephoto — stabilisation significantly improves image sharpness in the low light of the forest interior.
Rain cover for the camera bag insert — a small waterproof cover that goes over the camera section of your pack in wet conditions. Camera gear and water are an expensive incompatibility. This small item costs almost nothing and provides genuine peace of mind in the forest.
Documents and essentials
Gorilla trekking permit (printed or in a plastic sleeve — wet permits become illegible). Passport or ID. Cash in UGX for porter tip (20,000–30,000 UGX per porter is the standard) and any on-the-day expenses. A charged mobile phone with the lodge number and your operator’s emergency number saved. These should be in a sealed waterproof bag within an accessible outer pocket, not buried in the main compartment.
Total packed weight for a well-organised 20-litre daypack with the contents above should be between 4 and 6 kilograms. With a porter carrying this, the physical demand of the trek is substantially reduced, and you can focus entirely on the trail ahead and the encounter to come rather than the load on your back.
