The Ai-Ais/Richtersveld Transfrontier Park, which crosses into South Africa, features more spectacular scenery than wildlife, from the steep cliffs of the Fish River Canyon — one of the world’s largest — to the showy spring blooms of the Succulent Karoo biome, a biodiversity hot spot for succulent plants.
