I went with a group of friends on this spontaneous hike - we started at the top of the Wadi and walked back in to Jericho. The hike was fairly easy and we stopped at the beautiful Greek monastery on the way down (although the Greek monk there was not so friendly!). We headed down just before the sun was going down so the light was beautiful, especially as we got nearer to Jericho and the clouds turned all pink over the Jordan Valley and the evening call to prayer began from the mosque minarets - truly beautiful and atmospheric.
I would highly recommend doing this walk at sunrise or sunset to avoid the blistering heat of the Jordan Valley.
