Gorilla Trekking Etiquette — What to Do, What Not to Do, and Why It Matters
The rules governing gorilla trekking encounters at Volcanoes National Park and Bwindi Impenetrable National Park are delivered during the morning briefing and enforced by the ranger guides throughout the encounter. Some are legal requirements with consequences for non-compliance; some are best-practice guidelines whose enforcement depends on ranger attentiveness and visitor cooperation. All of them exist for reasons that are traceable to specific documented incidents or documented disease transmission pathways, and understanding the reasoning behind each rule produces more reliable compliance than receiving it as a list to be memorised.
The Seven-Metre Distance Rule
The minimum distance of seven metres between visitors and gorillas is the single most important rule in the encounter and the one most frequently compromised by visitor excitement rather than deliberate violation. When a juvenile gorilla approaches the visitor group — which curious juveniles frequently do — the correct response is to back away to re-establish the seven-metre gap, not to remain stationary (which allows the gorilla to approach within the minimum distance) or to move toward the gorilla (which compounds the violation). Rangers maintain the distance actively, but the distance is the responsibility of every visitor in the group, and the ranger’s instruction to “move back” should be responded to immediately and without discussion.
No Flash Photography
Flash photography is prohibited during the gorilla encounter. The prohibition is not about the gorilla’s response to light — habituated gorillas do not react strongly to camera flashes in the way that less habituated animals might. The prohibition is about the management of the encounter quality for all participants: a camera flash during a quiet, still gorilla family moment is a visual disturbance that affects both the animals’ behaviour and the experience of other visitors who are attempting to photograph in natural light. The practical implication is that gorilla photography in the forest requires camera settings appropriate to low-light forest conditions — ISO 1600 or higher, wide aperture (f/2.8–f/4), and image stabilisation. Learning these settings before the encounter is the difference between usable photographs and blurred images taken at settings appropriate for bright daylight.
Illness Exclusion
Any visitor who is ill on the morning of the trek — presenting with cough, runny nose, sore throat, fever, or any active respiratory symptoms — is required to withdraw from that day’s permit. This rule is applied at the park headquarters briefing, before the groups are assembled and dispatched to the forest. The financial consequence — the loss of the $1,500 permit cost, or the cost of the rescheduling process — is real, and the decision to withdraw when ill is one that some visitors resist. The reasons to comply — the documented susceptibility of habituated gorilla families to human respiratory pathogens and the deaths in Virunga gorilla families from diseases traced to human transmission — are sufficiently serious that the rule should be followed without exception.
Voice Control and Movement
The approach to the gorilla family, the encounter hour, and the departure are conducted in quiet voices or silence. There is no absolute prohibition on speaking — rangers communicate with guides and with each other, and visitors may speak quietly — but loud voices, sudden exclamations, and the sharp sounds produced by camera equipment being dropped or clipped are all disruptive to the family’s tolerance of the visiting group. The gorilla family’s indifference to visitor presence — which is the visible sign of successful habituation — is maintained by a visiting group that behaves in a consistent, predictable, non-threatening way. Unpredictable sounds and movements are the triggers that produce the silverback displays that become charged moments; avoiding them is good manners and good safety practice simultaneously.
Eating and Drinking in the Presence of the Gorillas
Food and drink are not consumed in the presence of the gorilla family. The prohibition has two bases: the disease transmission risk from food surfaces touched by multiple hands in a group snacking situation, and the potential for food to attract gorilla attention in a way that habituates the animals to seeking food from human visitors. Both consequences are documented in gorilla conservation management history. Water is consumed on the approach walk and during any break before the encounter; the one-hour encounter period is not a food-and-water break.
