In Namibia's desertscape, Etosha is the green lung where plentiful wildlife gathers in droves. It's here that endangered species thrive too, including the tough-skinned black and white rhino. Leave your lodge in a 4x4 to track the hoof prints of these solitary animals. After being brought to the brink of extinction, the rhino has found a haven in the wild spaces of Southern Africa and your seasoned guide will know just how, where and when (often before or after the midday heat takes hold) to find them as they trot between waterholes and graze on sweet grasses. You'll have the chance to see them up-close without disturbing their own itinerary for the day.
