Gorilla Trekking in the Volcanoes National Park offers visitors the unique opportunity of discovering the 10 families of gorillas that live within the national park. Visitors can enjoy a cup of coffee before the trek starts and will be separated into groups of 8 depending on their physical abilities. Each group is guided by a guide and two scouts who are well trained in emergency situations. The amount of time set aside per trek is different depending on where the gorilla family is situated. Some trips may take as little as half an hour and some taking the better part of the day.
