Volcanoes National Park is remote. It’s literally the very heart of Africa. Getting here is a challenge and trekking gorillas will take time. It’s as far from a zoo experience as you can ever possibly be.
So after you come to Volcanoes National Park why go gorilla trekking only once? On a second gorilla trek you will visit a different troop, a different family with their own behaviours. Some troops have multiple silverback males, others have newborns. You can experience contrasting emotions and gorilla trekking is too good to only do once.
Most preciously, a second gorilla trek will give you time. The first trek will fill you with anticipation, adrenaline and understanding. On a second trek you know exactly what to expect. You can put your camera down and let the entire experience sink in.
