My husband and I each had a child in a carrier we wore when we did this trail. It really wasn't as bad as people make it sound. I work out about 4 times a week, and my legs did not burn at all when we climbed back up. The thing that I found difficult was being able to breath as I climbed the stairs as such a high altitude. You just need to stop every little bit and get your breath. There are plenty of benches and ways to do that no problem. I even walked up and down several a portions of the stairs several times with my carrier on for different pictures. It really wasn't hat bad. It was a work out, but totally doable. I was even up for another hike to the bottom area of different falls a few hours later. The falls were beautiful and the view was great. This trail doesn't actually go to the base of the falls, but rather about 2/3 of the way down. This was a great hike, and a must do if you are in good health and in the area.
