Fish River Canyon

The Fish River is Namibia's longest interior river, and the gigantic canyon through which it passes is the largest in Africa. In fact, it is the second largest in the world, after the Grand Canyon in the USA. Parts of the canyon began to form about 650 million years ago, when plate movement cracked the earth. Much of the rest took shape from the river cutting its way through the granite river bed.

Today, this activity has created a breathtaking sight. In places, the river bed reaches a depth of 1,640 feet (550 metres), whilst the canyon itself is 100 miles (161 kilometres) in length, and at its widest point, it is 21 miles (34 miles) across.
