A beautiful hike, with tremendous views and really fun in the technical section (I would skip using the chains and simply climb up using the natural hand-holds). I've done it in both directions and prefer starting in McKelligon Canyon and ending at Trans-mountain road (the decent into the wash at Trans is a bit loose at the top but manageable). 2.5hrs start to finish, at an easy pace, but bring water as it can get hot!

Btw, we did manage to do it with one car, by having an Uber pick us up and bring us back to the start...
