Among the many populations of Golden Monkeys in Volcanoes National Park, there are two groups that are habituated to human visitors. One of these groups has an estimated 80 – 100 individual monkeys. Like Gorilla Trekking, visits take place in the morning and visitors are allowed to stay for 1 hour with the monkeys. As the number of visitors is not limited, permits can be booked the morning of the trek. The current fee for Golden Monkey permit is $100 per person.
