Exploring the gorge at foot, you will walk through a palm sided river bed, an excellent excursion if you do this during a summer visit to Algeria. Along the steep hill sides, mud-brick villages cling. If you're setting out for the whole walk to Biskra in the south, expect to use 3-4 days. Sleeping bag should be OK for trekkers. Restaurants are equally sparse, bring your own food and be ready to prepare it yourself.
Most larger villages has food stores, though.
