The Fish River canyon, situated along the lower reaches of the Fish River, is one of the most impressive natural beauties in the southern part of Namibia. With a depth of up to 550 metres, the Fish River Canyon is the second largest canyon in the world. The enormous gorge meanders along a distance of approx. 160 kilometres through the fissured Koubis massif all the way down to Ai-Ais. The canyon starts near Seeheim. It is 161 kilometres long and ends at Ai-Ais.
