We wanted to do Arches, but gut "stuck" with this hike instead. It took us approximately 45-50 minutes to hike this trail with several stops along the way.
My 12 year old daughter had no problem with the ladder and the ropes in the difficult part of the sections. HOWEVER if you can't hold on to a rope and support you weight I would not recommend this hike.
My mom (65 years) passed on this for that specific reason. I did however saw several older people in their 50 doing this hike with no problem at all. Other than the rope and the ladder this is a reasonably easy hike.
