Numas Ravine, slicing through the western face of the Brandberg, is another treasure house of ancient paintings. Most people ask their guide to take them to the rock facing the southern bank of the riverbed, which bears paintings of a snake, a giraffe and an antelope. It lies about 30 minutes’ walk up the ravine. After another half-hour you’ll reach an oasis-like freshwater spring and several more paintings in the immediate surroundings.
