Mountain Gorilla tracking experience can take from thirty minutes to three quarters of the day so one needs to prepare for both and also requires a certain level of fitness. This depends on several factors that include, mountain Gorilla movements, where the gorillas stayed the previous night and the mood of the gorillas. It may also depend on the people in your group since the guides/rangers move following the slowest person in the group. Katland Safaris Ltd is happy to provide all relevant advice
