The Fish River Canyon (Afrikaans: Visrivier Canyon or Visrivier Kuil, German: Fischfluss Canyon), is located in the south of Namibia. It is the largest canyon in Africa, as well as the second most visited tourist attraction in Namibia. It features a gigantic ravine, in total about 100 miles (160 km) long, up to 27 km wide and in places almost 550 meters deep.
The Fish River is the longest interior river in Namibia. It cuts deep into the plateau which is today dry, stony and sparsely covered with hardy drought-resistant plants. The river flows intermittently, usually flooding in late summer; the rest of the year it becomes a chain of long narrow pools. At the lower end of the Fish River Canyon, the hot springs resort of Ai-Ais is situated.
Public view points are near Hobas, a camp site 70 km north of Ai-Ais. This part of the canyon is part of the Ai-Ais/Richtersveld Transfrontier Park. The other 90 km of this canyon are privately owned.
