There's nowhere else in Africa like Fish River Canyon, which has been gouging this gorge for thousands of years with incredible results. It's huge - 160km (99mi) long and 27km (17mi) wide - and most of the canyon falls within Fish River Canyon National Park, where you can camp, walk, hike or relax in the bubbling hot springs.
At the northern end of the national park, there's the Hobas Information Centre, picnic sites, camp grounds, walking trails, and access to some of the best viewpoints in the canyon.
From Hobas, you can walk the five-day Fish River Hiking Trail to Ai-Ais, at the other end of the canyon. The 85km (53mi) walk follows the sandy bed of the river (it should contain water in May or June). There are also day walks at the northern end of the canyon.
At the southern end, Ai-Ais is a pleasant hot-spring oasis. The springs, which are piped into swimming pools and jacuzzis, apparently relieve rheumatism and nervous disorders. Ai-Ais has camping sites, bungalows and caravans.
