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. At some points the gorge widens a bit, and one can take a good look at the high rocks on either side.
