Based on the description of the 3 options, we selected moderate. Prior to arriving, we were given 3 more options with varying degrees of difficulty, and our group selected the 2nd most difficult. Our expectations were that we would be on an actual trail as opposed to ascending and descending rock formations with sloping and unstable surfaces that required foot placement on small ledges, use of hands and sliding down on your butt if necessary. The degree of slope was more than expected. I for one did not wear clothing that was appropriate for sliding down rocks. I would rate this as a moderate to advanced hike for experienced hikers. Early on my husband slipped and fell, getting several scrapes that required treatment. After that incident we were directed to walk out towards the road on a flat path, find a shady spot, and wait for the rest of the hikers to complete their hike. We did exactly that, and feel it was the best and safest option for us. We waited for an hour until we were picked up as promised at 10:30. Going forward I recommend you modify your description of the moderate hike and equip your guides with satellite radios, including an extra, in the event of a situation similar to ours where we had no means of communication because cell phones don't work.
