Rwanda enforces a strict set of gorilla trekking rules designed to protect both visitors and the gorillas: maintain 7 metres distance at all times, no flash photography, keep your voice low and movements calm, don't eat, drink or smoke near the gorillas, never touch them even if they approach you, and never trek if you're feeling unwell, since gorillas are genetically close enough to humans to be vulnerable to our respiratory illnesses.

Distance and Behaviour
The 7-metre minimum distance rule exists to protect gorillas from disease transmission and reduce stress on the family, and rangers actively enforce it throughout your visit, even if a gorilla approaches you first (which does happen). If a gorilla moves closer than 7 metres on its own initiative, the correct response is to stay calm, avoid direct eye contact, and let your guide manage the situation rather than backing away suddenly, which can be interpreted as a threat.
Touching a gorilla is never permitted, regardless of how close one comes or how calm the encounter feels. This rule exists for disease-transmission reasons in both directions, not just gorilla-to-human. Sudden movements, pointing directly at a gorilla, and raised voices are all discouraged, since gorillas read body language closely and calm, predictable behaviour from visitors keeps an encounter relaxed for everyone, gorillas included. If a gorilla performs what's known as a mock charge (a short, loud display rather than genuine aggression), the correct response is to stay still, avoid eye contact, and follow your guide's calm lead rather than run, which can trigger a real chase response.
Group Size and Time Limits
Visitor groups are capped at a maximum of 8 people per gorilla family per day, a limit set to keep habituation pressure on any single family manageable. Once you reach the gorillas, your viewing time is capped at exactly one hour regardless of how the encounter unfolds. Rangers keep time and will signal when it's up, which can feel abrupt but reflects the same conservation-first reasoning behind every other rule on this list. Travellers wanting more than an hour should look into the separate habituation experience, which allows up to four hours with a family still being acclimatised to human presence, under a different permit type with its own rules and pricing.
Trail and Group Rules Before You Reach the Gorillas
Some rules apply on the walk in rather than during the viewing hour itself. Litter of any kind, including small items like tissue or fruit peel, should be carried out rather than left on the trail, since even biodegradable waste can introduce unfamiliar bacteria into the ecosystem. Staying together as a group and following your ranger's lead on pace and route matters too. Wandering off, even briefly, isn't permitted, both for your own safety on unmarked forest terrain and because the group's collective movement is part of how rangers manage the approach to a sensitive gorilla family.
Walking sticks and hiking poles, if you've brought or rented one, are typically left with your porter or set aside just before the final approach to the gorillas, since the movement and sound of poles can be an unnecessary distraction at close range. Porters themselves stay a short distance back from the immediate viewing group once you arrive, though they remain close enough to assist if needed on the way back.
Photography Rules
Flash photography is strictly prohibited, as sudden bright light can startle or distress the gorillas. Standard photography without flash is welcomed; just be mindful of noise from camera settings and movement. See our photography tips guide for camera settings and gear suited to the forest's low light.

Health-Related Rules
If you're feeling unwell, particularly with any respiratory symptoms (a cold, cough, or flu-like illness), you should not trek. Gorillas share enough genetic similarity with humans to be vulnerable to our illnesses, and disease outbreaks have had serious consequences for wild gorilla populations historically. Most operators allow rescheduling in this situation, and disclosing symptoms honestly at check-in, even if it means missing your booked date, is taken seriously by park authorities for good reason.
If you need to cough or sneeze during the trek, turning away from the gorillas and covering your mouth reduces transmission risk, and a lightweight face mask is a sensible, low-effort addition to a daypack even outside of illness. There's also a minimum age of 15 for gorilla trekking permits: see our age limit guide for the reasoning behind this and how families with younger children typically plan around it.
What Happens If You Break the Rules
Rangers have the authority to end a trek early or ask a visitor to step back from the group if rules are repeatedly ignored, since their responsibility to protect the gorillas' welfare takes priority over any individual visitor's experience. This is rare in practice (the vast majority of trekkers follow guidance without issue), but it shows that these rules aren't just polite suggestions; they're actively enforced conservation measures with real consequences for non-compliance.
Why These Rules Exist
Mountain gorillas were, for decades, listed as critically endangered, and the population's slow recovery is closely tied to exactly this kind of careful, rules-based tourism management rather than unrestricted access. Our guide to the Dian Fossey grave and Karisoke Research Center covers more of the conservation history behind why these protections became standard practice in the first place. Every rule on this page traces back to one of two goals: preventing disease transmission between species that are genetically similar enough to share illnesses, or minimising stress and behavioural disruption to a family that tourism revenue depends on remaining wild and healthy.
| Rule | Primary Reason |
|---|---|
| 7-metre minimum distance | Disease transmission risk in both directions |
| No flash photography | Avoids startling or distressing gorillas |
| One-hour viewing limit | Limits habituation pressure and stress |
| Max 8 visitors per family | Manages cumulative daily disturbance |
| No trekking if unwell | Prevents introducing human illness to the group |
| No touching gorillas | Disease risk and behavioural disruption |
Beyond the gorilla-specific rules, general courtesy toward your rangers and porters (who are the ones actually making a safe, well-managed encounter possible) is worth extending too; see our tipping etiquette guide for guidance on recognising their work appropriately at the end of your trek.
Frequently Asked Questions
What happens if a gorilla approaches closer than 7 metres?
This can happen naturally. Stay calm, avoid direct eye contact, and follow your guide's instructions rather than moving away abruptly.
Can I reschedule my trek if I feel sick?
Most reputable operators allow rescheduling for illness given the risk to gorilla health. Always disclose symptoms honestly rather than trekking anyway.
What is a gorilla mock charge and how should I react?
A mock charge is a brief, loud display rather than a genuine attack. Stay still, avoid direct eye contact, and follow your guide's calm response rather than running.
Is there a maximum number of visitors allowed per gorilla family?
Yes. Groups are capped at 8 visitors per family per day, a limit designed to manage habituation pressure on any single family.
Can I bring food or drinks on the trek?
Snacks and water are fine during the hike itself, but eating, drinking or smoking is not permitted once you're in the gorillas' immediate presence.
Am I allowed to talk during the viewing hour?
Quiet conversation is fine, but loud talking, shouting or sudden loud noises are discouraged, since calm, low-volume behaviour keeps the encounter relaxed for the gorillas.
What if I need to cough or sneeze near the gorillas?
Turn away from the gorillas and cover your mouth. This simple habit meaningfully reduces disease-transmission risk, which is the same reasoning behind the sick-trekker policy.
Do children need to follow the same rules as adults?
Yes. Anyone old enough to trek (the minimum age is 15) is expected to follow the same distance, noise and health rules as every other visitor in the group.
Are rules different for the gorilla habituation experience?
The core distance and health rules stay the same, though the extended four-hour format and smaller group size come with their own specific guidelines covered in our dedicated habituation experience guide.
