Gorilla Trekking: What to Expect on the Day

Standing seven metres from a silverback mountain gorilla is not a wildlife sighting; it is a meeting. His hand looks like yours. He glances at you and returns to a leaf. Somewhere in the ferns behind him a female is nursing an infant, and a young blackback thumps past on all fours. You have one hour. Then the trackers politely wave you back down the mountain and it is over. Mountain gorillas live in only three countries — Uganda, Rwanda and the Democratic Republic of Congo — inside a handful of steep, wet, high-altitude forests. Trekking them is expensive, occasionally arduous, and consistently described by travellers as the most moving experience of their trip. This piece explains what a trekking day is really like, from the pre-dawn briefing to the descent, so you know what to prepare, what to wear, and how not to sabotage your own hour.

Key things to know

• ➜ Mountain gorillas live only in Uganda, Rwanda and DR Congo
• ➜ Permits cost roughly USD 800 (UG), 1,500 (RW) and 400 (DRC)
• ➜ One hour with the family, at least seven metres away
• ➜ Trek 1–6 hours through steep, wet, high-altitude forest
• ➜ Health rules are strict — do not trek if unwell
• ➜ Porters are inexpensive and transformative
• ➜ Photography with no flash, no big tripods
• ➜ Combines with chimpanzees, savanna safari and beach

Where mountain gorillas live

Mountain gorillas (Gorilla beringei beringei) survive in two populations: the Virunga volcanoes shared by Rwanda's Volcanoes National Park, Uganda's Mgahinga and DR Congo's Virunga NP; and Uganda's Bwindi Impenetrable Forest. Numbers have grown from a low of about 250 in the 1980s to over a thousand today thanks to intense protection funded largely by permits and tourism — one of conservation's genuine success stories.

Each park habituates a limited number of family groups for tourism, protects the rest for research, and rotates rangers and vets who monitor every family daily. Only eight visitors per family per day are allowed anywhere.

• ➜ Volcanoes NP, Rwanda
• ➜ Bwindi Impenetrable Forest, Uganda
• ➜ Mgahinga Gorilla NP, Uganda
• ➜ Virunga NP, DR Congo
• ➜ Sub-populations: Bwindi and Virunga

A day in the forest

You leave your lodge around 5:30 am, drive to the park headquarters and gather with other visitors for a briefing at about 7 am. Groups are assigned in eights based on a mix of fitness, age and preference for shorter or steeper hikes. Rangers set off before dawn to find each family; your guide meets them on radio during the trek and steers you towards where they have settled.

The trek itself can be anything from a 45-minute stroll to a five-hour scramble on wet, slippery slopes at 2,000–3,000 m. The last stretch is often the hardest, off the path, through nettles and knotted vines. When you arrive, you leave day packs and poles with the porters, wear a face mask, and step in — the family is often just metres away, moving through vegetation, feeding, playing, or sleeping.

The one hour rule and gorilla etiquette

Guests get sixty minutes with the family — a rule to minimise stress and disease transmission. Move quietly, speak in whispers, avoid coughing (turn away and lower your mask). The seven-metre distance is not always achievable if a gorilla walks toward you; in that case you must slowly step back if space allows or freeze and lower your eyes. Never turn and run.

The silverback usually ignores you. Blackbacks may thump the ground. Youngsters occasionally approach and are the greatest test of not moving — enjoy it. If a gorilla charges as intimidation, drop to a crouch, look at the ground, and let the guide handle it. Trackers know each animal personally and read behaviour long before you do.

• ➜ Seven metres, ideally
• ➜ One hour maximum
• ➜ Whisper only
• ➜ Turn away to cough
• ➜ Do not eat, drink or point

Fitness, altitude and porters

You do not need to be an athlete but you do need to walk for hours on steep, muddy ground. Bwindi is famously known as "impenetrable" for a reason — thick vegetation, roots and hidden mud. Rwanda's volcanoes are steeper but shorter; Uganda's Mgahinga is short but at higher altitude; Virunga in DRC is slick from lava and rain.

Altitude is real. Treks range 2,000–3,500 m, and pace matters more than power — go slow and drink. Hire a porter (roughly USD 20–30) even if you feel fine; they carry your bag, offer a hand on tricky steps, and their income supports former poachers and community members. It is the single most transformative decision on trekking day.

• ➜ Solid hike-tested boots
• ➜ Waterproof shell and gaiters
• ➜ Long trousers and thin gloves for nettles
• ➜ Small daypack (porter-friendly)
• ➜ Water, snacks, camera + one lens

Photography and rules

No flash. Ever. Auto ISO up to 6400, aperture priority around f/4, shutter 1/250 or faster to freeze micro-motion in low forest light. A single fast telephoto (70–200 or 100–400) is enough; wide lenses capture context, but distance limits their usefulness. Turn off any audible focus beep and never lie down on the ground or crawl.

Spend the first ten minutes without your camera. Simply watch. The images that people cherish are usually taken in the second half of the hour, when the family is used to you and you have relaxed enough to compose.

Health rules and permits

Mountain gorillas share more than 98% of our DNA and are vulnerable to human respiratory diseases. Anyone with a cold or fever is legally required to skip the trek — most parks refund or reschedule. Face masks are mandatory in Rwanda and Uganda. No touching. Age minimum is 15 across all three countries. Yellow-fever vaccination is required to enter.

Permits: Rwanda USD 1,500 per person per day, Uganda USD 800, DR Congo USD 400. Include the trek fee, ranger and tracker escort, and the one-hour visit. Book well in advance in high season (June–September, December–February). Volcanoes NP habitually sells out; Bwindi has more capacity but the best sectors (Ruhija, Buhoma, Rushaga, Nkuringo) each need dedicated logistics.
