Gorilla trekking rules in Uganda and Rwanda are strictly enforced by wildlife authorities to protect endangered mountain gorillas and human visitors alike. Before entering Bwindi Impenetrable Forest or Mgahinga Gorilla National Park, head rangers deliver a mandatory morning briefing covering 12 core rules. These rules focus on health protection, physical distance, group behavior, and safety protocols during gorilla encounters.
Why Gorilla Trekking Rules Exist
Mountain gorillas share over 98 percent of human DNA. This genetic closeness makes wild mountain gorillas extremely vulnerable to human respiratory illnesses, including influenza, common colds, and airborne viruses. Because wild gorillas lack immunity against human diseases, an outbreak could prove catastrophic for an entire gorilla family.
Strict regulations established by the Uganda Wildlife Authority and Rwanda Development Board safeguard fragile gorilla populations while maintaining a safe, respectful habitat for ecotourism.
The 12 Things Rangers Will Tell You Before Your Trek
1. Age Restriction: Minimum 15 Years Old
Trekkers must be at least 15 years of age on the day of the trek. Children under 15 are excluded because young individuals carry higher risks of childhood communicable diseases and may panic if a silverback makes sudden vocalizations.
2. Group Size Limit: Maximum 8 Trekkers Per Family
Only eight visitors are permitted to visit a single habituated gorilla family each day. Limiting human group sizes minimizes stress on gorillas and reduces exposure to potential airborne pathogens.
3. Time Limit: Maximum 1 Hour With Gorillas
Once your ranger locates the gorilla family, your viewing time is limited to exactly sixty minutes. Restricting contact time ensures wild gorilla routines such as foraging, grooming, and resting remain undisturbed.
4. Maintain Distance: Minimum 7 Metres (23 Feet)
Trekkers must remain at least seven metres away from gorillas at all times. If curious young gorillas approach you, rangers will instruct you to step back slowly to preserve safe spacing.
5. Stay in a Tight, Cohesive Group
Never wander away from your lead ranger or scatter around the gorilla family. Staying together in a compact group helps gorillas recognize you as a non threatening, single presence.
6. Keep Voices Low and Movements Calm
Speak in quiet whispers during the approach and while observing gorillas. Avoid sudden hand gestures, loud laughter, or rapid body movements that wild animals could interpret as aggressive threats.
7. No Flash Photography or Video Lights
Flash photography is strictly prohibited. Bright flashes intimidate gorillas and can trigger defensive reactions from silverbacks. Ensure flash functions and focus assist lights are completely turned off before arriving.
8. No Eating, Drinking, or Smoking Near Gorillas
Consuming food, drinking liquids, or smoking within 27 metres of gorillas is banned. Food particles or dropped scraps can transmit bacteria, while human snacks might attract curious primates.
9. Turn Away When Coughing or Sneezing
If you need to cough or sneeze while near gorillas, turn your head away completely and cover your mouth and nose with your elbow or a handkerchief to prevent aerosol droplets from spreading.
10. Proper Sanitation and Waste Disposal
If you need to use the toilet during the forest trek, inform your ranger immediately. The ranger will dig a trench at least 30 cm deep, which must be fully covered afterward to prevent wild animals from unearthing human waste.
11. How to Respond to a Gorilla Charge
If a silverback gorilla charges, beats his chest, or vocalizes loudly, remain calm. Crouch down slowly, lower your eyes, and avoid direct eye contact. Never run away, as running triggers a natural chase instinct.
12. Do Not Trek If You Are Sick
If you feel sick with a cold, fever, cough, or stomach upset on trek morning, report to park wardens. Trekkers showing illness will be excluded from forest entry to protect gorillas, with permit rescheduling options provided by park policy.
Ranger Wisdom on Trail Etiquette
Your lead ranger and armed escorts are experienced conservationists who know every gorilla family by name and personality. Following ranger instructions immediately ensures a smooth, awe inspiring, and safe wildlife encounter.
Real Guide Field Story
In March 2026, Senior Specialist Brian led a private group in the Rushaga sector of Bwindi. During their encounter with the Nshongi gorilla family, an energetic juvenile gorilla walked directly toward a guest named Sarah. Remembering the morning ranger briefing, Sarah kept completely still, lowered her eyes, and let the ranger gently guide her step back. The silverback watched calmly, recognized the respectful space, and continued feeding on wild celery. Sarah described that peaceful moment of mutual respect as the highlight of her lifetime travels.

Frequently Asked Questions About Gorilla Trekking Rules
What happens if a gorilla comes closer than 7 metres to me?
Because habituated gorillas are comfortable around humans, curious juveniles or silverbacks may walk toward you. If this happens, remain calm, stand your ground or step back slowly as directed by your ranger, and keep your hands low.
Are face masks required during gorilla trekking in Uganda?
Yes. The Uganda Wildlife Authority requires all trekkers to wear surgical or N95 face masks when observing gorillas to prevent human droplets from reaching the animals.
Can I get a permit refund if I report sick on trek morning?
According to Uganda Wildlife Authority guidelines, visitors who declare illness at park headquarters before the trek receive a partial permit refund or can reschedule their permit for a future date upon medical evaluation.
Can I bring a trekking pole into the forest?
Yes. Park rangers strongly recommend using a sturdy wooden walking stick, which is provided at park headquarters or supplied by your lodge, to maintain stability on steep inclines.
