One of Namibia's
great natural sights, it is claimed to be the second largest in the
world.
(They made the same claim about the Colca Canyon in Peru too.)
The
Fish River Canyon probably formed about 500 million years ago. However,
the gorge was not only created
by water erosion, but also through the collapse of the valley
bottom due to movements in the earth's crust.
With
a depth of up to 550 metres, the enormous gorge meanders along a
distance of 165 kilometres
and is up to 27 km wide,
Only overnight hikers are allowed down into the canyon.
I visited the canyon during my
47-day, 5-country trip in southern Africa in 2009.
We walked about 3 km along the rim between view points.
