The trekking starts in the morning and after breakfast you are transferred to a ranger’s station for briefing after your rangers/guides will lead you through the cultivated lands and then into the dense rain forest and as close as is allowed to a gorilla family. The rangers monitor the gorillas on a daily basis and have a fairly good idea of where they are. Trekking can take anywhere from 45 minutes to 8 hours and it can be quite strenuous, so a reasonable level of fitness is required.
To ensure the gorillas do not get too used to the presence of humans and because they share many of our genes (and are therefore able to catch our diseases), the maximum time permitted to spend with them is 1 hour. You will have plenty of time to watch their activity and to take photographs. The rangers will be able to provide you with a background to the family/group you are visiting. Once your hour is up, you trek back out of the rain forest to your meeting point. Clients intending to do this trip should realize the demands and unpredictability of the areas visited.
The families/groups of gorilla that are sought out on our jungle trek have been habituated, they have not been tamed and their behavior is not demonstrably different from that of non-habituated groups. Nobody forces them to stay with us for the allotted hour, and they can fade into the forest as you appear, if they wish to do so. Further, as gorillas are sensitive to human disease, the park authorities will not allow anyone they consider to be in poor health to visit the gorilla groups. Additionally, no children under 15 years of age are permitted to track the gorillas.
