Fish River Canyon in Namibia: Hiking and Self-Drive Visit

The main site, Hobas, is reached on a well-maintained gravel track from the B4 (Keetmanshoop–Lüderitz road) or from Ai-Ais further south. From the Hobas camp, the flagship viewpoint — often called Hiker's Point or Main Viewpoint — is a ten-minute walk away on a flat, easy path, no 4x4 or particular fitness required.

Several other viewpoints are strung along the track between Hobas and Ai-Ais, notably toward Sulphur Springs (Ai-Ais Hot Springs) in the south: each offers a different angle on the canyon's bends, with the best light early morning or late afternoon, when the low sun carves out the relief of the rock.

The full traverse of the canyon — roughly 85 km on foot over 4 to 5 days, fully self-supported with no resupply along the way — is reserved for experienced, physically fit hikers. Namibian regulations require a group of at least three people (solo hiking is never allowed) and, depending on the period, a medical certificate no more than forty days old confirming fitness for the effort.

This hike is only open during the cool season, roughly May to mid-September: outside that window the heat inside the canyon becomes dangerous and the route simply closes. Spots are limited and are booked several weeks ahead through Namibia Wildlife Resorts (NWR).

The Ai-Ais camp, with its natural hot springs, marks the southern end of the canyon and the finishing point of the long hike. For a self-drive traveller not walking the full 85 km, Ai-Ais is still a pleasant stop in its own right — a hot soak after a long drive — and a good base before heading to the South African border or back up toward Lüderitz and Kolmanskop.

The canyon sits in one of the hottest, driest parts of the country: even a short walk to a viewpoint can catch you out at midday in the hot season, with no shade for kilometres. Setting off early, carrying far more water than seems necessary, and avoiding any extended walking between 11am and 4pm remain the basic rules — see our dedicated article on preventing heatstroke on a road trip for the warning signs to know.

Despite this aridity, the canyon holds a surprisingly rich biodiversity: a study by Antje Burke, published in 2017 in the Namibian Journal of Environment, recorded 835 plant species across the Greater Fish River Canyon landscape, 265 of which were rated of particular conservation importance (study available online). The river itself, dry for most of the year, remains the driving force behind this landscape: a study by Tamir Grodek and co-authors, published in 2024 in the journal Geomorphology, analysed how rare flash floods and upstream dams reshape the canyon's dynamics, one of the world's most extreme examples of a desert environment shaped by water (study available online).
