Wadi Numeira is one of several slot canyons or "siq" in Jordan and one of the most accessible. It is located just off the Jordan Valley Highway, near the Dead Sea. Surprisingly, it receives few visitors and I basically had the canyon to myself. After only a few hundred meters the walls narrow. At various points you have to scramble across some boulders. It is a wonderful hike.
At this point the canyon is still widebut the canyon soon narrowsThe canyon was shaped by water so don't visit if there's a chance of heavy rainOne of the wider sections. Beware of falling rocks.Wadi Numeira is pretty awesome. I was genuinely surprised (and glad) there were no other hikers.It is tempting to keep going to look what's behind the cornerThis is where I returnedAt some sections the walls are covered with tropical vegetationThe entrance/exit of Wadi Numeira
