Here's a view from along the stream that runs the full length of the gorge, to Selime. It will take you some four hours, with the option to get out halfway. I think it is well worth the trouble of going the full length. The path runs on either side, although I think the left bank (going downstream) may be a bit easier till the halfway-point. Or maybe I just took a wrong term when I took the right side, and found myself climbing up and down big boulders.
