The most strenuous hike at Redrock Canyon climbs 2,000 ft in 2 hrs to the top elevation of about 6300ft. I can see where it would be very hard if you aren't in decent shape. The views from the top are worth the effort you have to put in. The trail is not very clear cut. On the way up you just kind of find your way with trial and error. There is some loose rock and steep areas you will encounter. It took us 3 hrs to hike the whole thing rpund trip and we relaxed and took in the scenery at the top for an additional 30 mins. I would advise some of the easier or moderate trails if you aren't in decent hiking shape. I am in good shape and hike often. By the end of our trip I admit I was pretty tired.
