You have to work a little if you start in Mckelligon Cannyon going to the Transmounatin side,but after you climb the "window" a  13 ft wall (aprox), is pretty easy . Difficult if is your first time hiking. I went with my kids, 11 and 14 at that time, the guide thought that we wasn't going to finish but we did.

The lenght is Aprox ,I forgott the lenght and the hours we took to complete it ,has been a while.
