I wish I could remember what trail we were on, and it was strenuous, but we went down as far as the mules went before they turned around and went back up. If we had gone farther down, we would have been hugging the cliff walls on a good portion of the trail.
Yup! That's the North Kaibab trail! I think you went as far as the falls, but I could be wrong. I've seen pictures of the part of the trail you describe. It's a knife-edge drop on one side and a straight up cliff face on the other. It's not a place I'd like to find myself at night. I think there've been a few deaths from falling there.
