One & Only Gorillas Nest: Eye to eye with swaying eucalyptus trees, One&Only Gorilla’s Nest is the closest resort to Volcanoes National Park. In and around the resort, there is an incredible topography of peaceful sleeping volcanoes that defy gravity, creating an awe-inspiring atmosphere and perfect setting for cyclists. One&Only Gorilla’s Nest is set against the historic volcanic mountains of Volcanoes National Park – the first national park in Africa and home to endangered mountain gorillas. This is a place that has fostered a spirit of love and protection over the years, most notably from renowned primatologist Dian Fossey.
