How many people are in a group when tracking gorillas in Uganda?

And the rules...

There can only be a maximum of 8 people tracking the gorillas per group, per day. It is important that all gorilla tracking participants familiarize themselves with the following regulations and rules of conduct:

- You must, at all times, follow the instructions of your guide. He is in contact with the gorillas every day and understands them well. Always remain in a quiet, compact group behind the guide, who will attempt to position you in such a way that the dominant male of the group can see you at all times. Please try to keep a minimum distance of 7 metres at all times from the gorillas.

- If the dominant male gorilla (usually a silverback) approaches very closely, or if he charges, it is very important that you do not move backwards. Remain exactly where you are, look downward, and adopt a submissive, crouched posture.

- Never make any sudden moves or loud noises in the presence of the gorillas.

- If a young gorilla approaches, never under any circumstances make any move to touch it. Your guide, in certain instances, may take steps to discourage a youngster from trying to touch you, as this could create a threatening situation with the dominant male.

- If a gorilla stares at you, look away or down.

- Avoid taking an excessive number of photographs, and never use a flash when photographing the gorillas.

- Only visitors in good health at the time of tracking will be permitted to track gorillas, as gorillas are susceptible to colds and other respiratory diseases transmitted by humans. All visitors must be physically fit and capable of enduring a walk of several hours in difficult terrain.

- Each gorilla family may be visited only once each day, during the morning hours.

- At this time, all gorilla visits are limited to a maximum of eight (8) persons per gorilla family for a maximum length of one (1) hour. Due to the already-limited number of persons allowed to visit the gorillas each day, it is not possible to do gorilla tracking on a private basis.

- Smoking, eating, and/or drinking are not permitted within 200 meters of a gorilla family. Please avoid smoking at any time if possible.

- It is prohibited to destroy any vegetation unnecessarily and to make open fires in the national parks and reserves. The flora and fauna of national parks and reserves are strictly protected.

- All visitors must carry their own litter with them out of the park or reserve, leaving nothing behind.

- Children under the age of fifteen (15) cannot be accepted on gorilla tracking excursions.
