Gorilla trekking rules and etiquette exist for one reason above all: mountain gorillas share close to 98% of human DNA and can catch human respiratory illnesses. Every rule on this list traces back to protecting a genuinely endangered population, not just visitor experience.
Key Highlights
- Minimum distance from gorillas: 7 meters at all times
- No flash photography, loud noises, or sudden movements
- Visitors who are unwell should not trek, even with a booked permit
- Maximum group size: 8 visitors per family, for one hour
- No eating, drinking or littering in the gorillas’ presence
The Core Rules
Stay at least 7 meters back at all times, keep your voice low, and never use flash photography — it startles gorillas and disrupts natural behavior. No eating or drinking while with the family, and nothing gets left behind in the forest, including tissues or wrappers.
Why Health Rules Matter Most
Because mountain gorillas are genetically close to humans, they’re vulnerable to our colds, flu and other respiratory illnesses in ways that can be fatal to them. If you’re feeling unwell — even mildly — on trekking day, tell your guide before setting out. Rangers will reschedule a sick visitor rather than risk the family’s health, and most operators build some flexibility into permit bookings for exactly this reason.
If a Gorilla Approaches You
It happens more often than visitors expect, particularly with curious juveniles. The rule is simple: stay still, avoid direct eye contact with a silverback, and let your guide manage the situation. Never approach a gorilla yourself, even if it’s moved closer than the required distance.
Photography Etiquette
Photos are welcome and expected, but flash is never permitted. Given Bwindi’s low forest light, most experienced trekkers bring a camera capable of higher ISO performance rather than relying on flash — see our packing list for gear recommendations.
Group Behavior
Groups are capped at 8 visitors per family specifically to limit stress on the gorillas. Follow your guide’s instructions on movement and positioning rather than jockeying for a better angle — rangers will ask you to move if you’re too close or too loud.
Frequently Asked Questions
What happens if I break a rule during the trek?
Your ranger will correct you immediately — most breaches are minor and unintentional, like stepping too close for a photo, and are simply addressed on the spot.
Can I still trek if I have a mild cold?
You should disclose this to your guide before trekking. Depending on severity, you may be asked to skip the trek to protect the gorillas, with rescheduling options discussed with your operator.
Is it true gorillas sometimes touch visitors?
Rare but possible, usually from curious juveniles. Visitors are instructed to stay passive and let the ranger manage the encounter.
