Access to the place
Hiking to the start 10'
Cross the sandy valley on the east side to reach the starting point. The Khazareh Canyon is easy to spot, with a wide lateral fault that can almost be seen from the front. Reach the foot of the cliffs on the right to find the starting point.
The canyon crosses from west to east and can be completed in around 2 hours. You'll need an 80m rope to return via the Khazareh Canyon, and possibly a 40m safety rope for exposed passages, as well as all the associated gear (harness, helmet, descender...).
Enter a stony ravine that climbs to the right, with an easy-to-spot passage (Goat's gully), and reach the plateau. Cross due east to find a path that makes a large S, first to the left, then to the right. This leads into the bed of a narrow wadi. Follow it zigzagging upwards until it turns due east and closes off. At this point, there's a stone arrow on the ground, and you have to climb to the far left.
Cross a small, well exposed slab and head right uphill to reach a sort of slightly exposed aerial ledge at the top of the canyon (in fact, this passage allows you to avoid the very closed, impassable part of the canyon). You soon reach the bed of the wadi. Continue until you reach a cul de sac, where you must turn left, then right, then left (cairns indicate the way). The passages are narrow and very steep. We then climb a small slope to reach a small pass.
Descend to the left, taking a step that's not easy, and end up on Bedouin steps. Follow this path and you'll come to a wider opening. Continue, passing an area of large boulders below or above. You can now see the orange exit dune. The end consists of following the right-hand flank to finally reach the sandy floor and finish at the foot of the dune.
This can be done from the south, bypassing the Um Ishrin jebel over the sand, but this seems a long way off (or you can be picked up by a Bedouin cab). The best way is to loop around to the north and cross the Um Ishrin jebel again via the Khazareh Canyon.
