Map & topo
Hiking to the start 2h30
From the village reach the small mosque to find below it the path recently marked with red, white and yellow flags. Follow the path before branching off downhill to find the canyon bed (30′). A few easy climbs, and you're at the top of Wadi Hijri and the uninhabited village of Masirat Al Shreeqiyeen. Descend further to reach the palm grove and the hanging pool, the end of the signposting (approx. 1h30 from the start). A compulsory swim with an aerial view of the canyon entrance. After a refreshing swim, descend behind the pool and head off to the right, staying high and cutting through the terraces to find an access gully to the bed of the wadi, with a few not-too-difficult climbs.
South-facing, the canyon is aquatic throughout, with numerous swimming pools and reaches. Many waterfalls are avoidable or passable, with jumps between 3m and 7m. 5 abseils, 3 of them compulsory, the highest under a 25-meter waterfall. All belays are equipped on 1 point, some with no ring or no quick link (to be provided). Wetsuits are preferable, even if the water is very pleasant in hot weather.
Allow around 8h for the descent from the start of the 1st abseil to the end of the aquatic section, including the bivouac under the large 120m waterfall of Aqabat El Biyout.
Part 1: obstacles (6h)
Abseil 1 (12m): after 2h of aquatic hiking in the wadi and just after crossing the finish of the canyon coming from Hulailat on the left (large crossroads).
Rappel 2 (22m) under a waterfall 1 hour later, arrival in a large swimming pool.
Rappel 3 (10m) easy, ending on the left on a rocky slab to avoid a splash.
Rappel 4 (8m, ring missing) avoidable with a 4/5m jump.
After 6h of descent, at abseil 5 (10m, 1 point without ring), this is the place to climb to the left and reach the bottom of the large 120m waterfall at the finish of the Wadi Aqabat El Biyout. Bivouac by the pool and end of obstacles.
Part 2: aquatic hike (2h)
From the bivouac, return to Wadi Hijri and cross to the left to reach the torrent bed, avoiding abseil 5. There's almost 2 hours of aquatic hiking left, without abseiling. The waterfalls can all be avoided by looking for passages to the right or left. The watery end is marked by 2 long reaches to swim, the wadi then bends to the left and the water disappears. Start of the return journey.
At the bend, where the water disappears, there's another 1h to 1h30 of walking in full sunlight, on gravel, to reach Wadi Tanuf and the junction with Wadi Qasheh.
