Widely regarded as the second largest canyon in the world after
the USA's Grand Canyon, the Fish River Canyon is located in
southern Namibia in the eastern Namib Desert. The 100-mile (161km)
long canyon was caused by a fracture in the earth's crust and then
further carved by the erosion of the Fish River over millions of
years. The river can still become a torrent of fast-flowing water
after heavy rainfall in summer, but dries up into occasional
semi-permanent pools during the winter months. The main attraction
of the area is hiking, but hiking the Fish River Canyon can only be
undertaken during the winter months, requires a high level of
fitness and good health and offers no facilities whatsoever. The
five-day trail covers 53 miles (86km) and is the best way to take
in the canyon's magnificent immensity, passing beneath the sheer
cliffs with their visible rock strata patterns towering 1,640ft
(500m) above the harsh, rock-strewn plain. The canyon comes to an
end at Ais-Ais (meaning 'burning water' in Nama) where one of the
most famous hot spring resorts in the country is located, and
hikers can look forward to a relaxing soak in the therapeutic hot
water after completing the trail.
