Gorges d'Arak Canyon Walk
A spectacular canyon walk through ancient sandstone gorges carved by prehistoric rivers, now dry. The narrow passageways open into vast amphitheaters, and the stratified red-and-orange rock walls glow intensely at sunset.
The Gorges d'Arak canyon walk explores a series of ancient sandstone gorges in the central Algerian Sahara, located approximately 50 kilometers north of Aïn Salah (In Salah) in Tamanrasset Province. The gorges were carved by prehistoric watercourses that flowed when the Sahara was a wetter environment, and the resulting canyon system features narrow passageways, wide natural amphitheaters, and stratified rock walls in shades of red, orange, yellow, and white that intensify dramatically at sunrise and sunset.
Access to the gorges is via National Road 1 (RN1), the trans-Saharan highway that passes directly alongside the canyon entrance. Visitors with private 4WD vehicles can park off the main road near the gorge entrance. The area is a natural stopping point for trans-Saharan convoys and organized desert tours traveling between Algiers and Tamanrasset. No formal permit is required for the canyon walk, though independent travelers should comply with general Algerian regulations for remote desert travel, including notifying the nearest gendarmerie post of their itinerary in some cases. The nearest fuel and supplies are available in Aïn Salah.
The route covers approximately 10 kilometers with 150 meters of elevation variation over 4 to 5 hours. The terrain varies from sandy washes at canyon bottoms to compacted sandstone ledges along the walls. Some scrambling over boulders is required in the narrower sections. The main canyon splits into several arms, and exploring the secondary gorges adds both distance and interest to the walk.
The canyon walls rise to approximately 50 to 80 meters at their highest points, creating narrow passages that filter the desert sun and provide partial shade during morning and late afternoon. The stratification of the rock is particularly striking at sunset, when low-angle light turns the walls deep amber and copper. The photogenic narrows are most accessible in the central section of the route, approximately 3 to 5 kilometers from the start.
Desert silence is a defining feature of this walk—the canyon walls block wind and ambient sound, creating an unusual stillness. Wildlife is limited but includes desert monitor lizards, various birds of prey nesting in the cliff faces, and occasional desert hares. There are no facilities within the canyon: no shade structures, toilets, or water sources. All water and supplies must be carried for the entire outing. Navigation within the canyon follows intuitive drainage channels in the main gorge but requires care when exploring side arms.

Tips
- Start the walk before 8:00 AM or after 4:00 PM to avoid the most intense midday sun and to benefit from the best light on the canyon walls.
- Carry at minimum 3 liters of water per person; there are absolutely no water sources within the gorge system.
- A wide-brimmed hat, sunglasses, and high-SPF sunscreen are mandatory—shade is limited outside the narrow passages.
- Inform the nearest gendarmerie post in Aïn Salah of the intended route and estimated return time before entering the gorge.
- Soft-soled approach shoes provide better grip on polished sandstone surfaces than hard-soled boots.
FAQ
Is a guide necessary for the Gorges d'Arak walk?
A guide is not legally required for this particular walk, but familiarity with the terrain is helpful in the maze-like interior gorges. Local guides can be arranged in Aïn Salah for those unfamiliar with desert navigation.
Are there facilities at the gorge entrance?
There are no permanent facilities—no toilets, café, or information centre. The main road passes nearby and vehicles can be parked off the road, but there is no formal infrastructure within the gorge.
How does the gorge look at different times of day?
Sunrise and sunset produce the most spectacular canyon colors, with stratified rock glowing in warm amber and copper tones. Midday light is harsh for hiking but can be good for photographing overhead rock forms. Early morning is most comfortable for walking.
Can the gorge be visited as a day trip from Aïn Salah?
Yes. Located off National Road 1 approximately 50 km from Aïn Salah, the gorge fits comfortably into a day trip. With a 4–5 hour walk and driving time, plan for a full day and carry sufficient water and food.
Accessibility

When to visit
November through March provides comfortable hiking temperatures in this low-elevation desert canyon. Summer heat (June–August) renders midday walking dangerous; spring and autumn are also acceptable, though sandstorms are more frequent in March and April.
