A Namibian icon, quiver trees are tall with thick round trunks topped by spiny branches once used by bushmen as spears for hunting. A geological phenomenon, the Giant’s Playground has towering boulders stacked on top of one another as if placed there by giants. Both the Quiver Tree Forest and the Giant’s Playground form eerie silhouettes during the blue hour and their surfaces take on a warm hue during the golden hour. If you’re into photography, this is a twilight scene you’ll want to capture.
