Fish River Canyon

If the Grand Canyon is America’s geological masterpiece, Fish River Canyon is Africa’s. At 160 km long, up to 27 km wide and 550 metres deep, it is the world’s second-largest canyon — and unlike the Grand Canyon, it has relatively few visitors, no shuttle buses, no guardrails and a 5-day hiking trail along the canyon floor that is widely considered one of Africa’s finest long-distance walks.

The canyon was carved over 600 million years by the Fish River, the longest river entirely within Namibia. The geological layers exposed in the walls read as an archive of southern Africa’s ancient history: basement granite over a billion years old at the bottom, sedimentary layers above recording ancient seas and inland basins, capped by the more recent desert plateau. It is, in the most literal sense, deep time made visible.

Where is Fish River Canyon?

Southern Namibia, approximately 170 km north of the Orange River (South African border). The main visitor infrastructure is at Hobas Camp on the canyon rim and Ai-Ais Hot Springs Resort at the southern end. From Windhoek: 760 km, approximately 8–9 hours. From Keetmanshoop (the nearest town with accommodation): 130 km, 1.5 hours.

The canyon hike

The Fish River Canyon Hiking Trail runs 85 km along the canyon floor from Hobas to Ai-Ais over 5 days, following the Fish River as it winds between the canyon walls. It is an unguided, unsupported trail — no huts, no water except the river pools, no trail crew — which makes it considerably more serious than most African multi-day walks. Requirements:

• Minimum group of 3 people (solo hiking not permitted).
• A doctor’s certificate of fitness (issued within 40 days of the hike).
• Permit from NWR (Namibia Wildlife Resorts), bookable online.
• Season: May 1 to September 15 only.

The terrain alternates between rocky river bed, pools requiring wading, and sand banks. Water is from the river and must be treated. The final day ends at the Ai-Ais hot springs, where hikers traditionally soak in the thermal pools for an hour before the transfer back to Hobas.

The rim viewpoints

For non-hikers, the canyon rim road at Hobas provides a series of viewpoints over the canyon. The Main Viewpoint and Hiker’s Viewpoint (where you can look down the full depth of the canyon to the river 550 metres below) are the most dramatic. Sunrise from the Main Viewpoint, when the canyon walls turn from grey to terracotta to gold in sequence, is worth setting an alarm for.

Ai-Ais Hot Springs

At the canyon’s southern end, the Ai-Ais Hot Springs Resort (the name means “scalding hot” in the Nama language) has natural thermal pools at 60°C cooled to swimable temperature, chalets, camping and a restaurant. It is a destination in itself for Namibian holidaymakers and the logical end point of the canyon hike.

Combine Fish River Canyon with…

• Kolmanskop and Lüderitz — the southern Namibia coastal circuit.
• Sossusvlei — continue north for the Namib dune sea.
• Gondwana Cañon Park — the private conservancy adjacent to the canyon with guided drives and accommodation.

Frequently asked questions about Fish River Canyon

How difficult is the Fish River Canyon hike?

Strenuous. The terrain is rough, distances are long (up to 25 km per day) and conditions are exposed. No technical skills are needed but strong fitness, blister management, and heat regulation experience are essential. Many hikers consider it the hardest non-technical trail they’ve done.

Is Fish River Canyon bigger than the Grand Canyon?

It is the world’s second-largest canyon but the Grand Canyon is larger in depth (1,857 m vs 550 m) and volume. Fish River Canyon is longer (160 km vs 446 km of the Grand Canyon gorge) and considerably wider in places.

Can you see Fish River Canyon without hiking?

Yes — the rim viewpoints are accessible to all visitors and are genuinely dramatic without any hiking. Day visitors without accommodation bookings are welcome at the Hobas viewpoints.
