This hike is very challenging. My husband and I did the cholla trail. We don't hike often and we are both in decent shape. We started the hike at 6:45 and I would recommend starting earlier than that. It got pretty hot at the end. I would say it is about 75% hiking and 25% scaling rocks using all four extremities. It's doable, but pretty tough. My husband went all the way to the top, I stopped about 300 feet from the top, and I'm glad I did. The views were phenomenal and my husband says the worst part was the part I missed. Going up to the top took about 1.5 hours, coming down was obviously way easier and way faster. Bring a lot of water. We brought about 10 bottles of water and 2 huge gatorades and that was about right. I wouldn't have wanted to have any less. You need a backpack or something. You can't climb with anything in your hands. If I ever did it again, I would start earlier in the morning, eat a good breakfast, and bring something that would keep my water at least cool so it wasn't hot when I drank it.
