This river was so much fun. I love the heat so it the 100° weather didn't faze me. However, if you are going with a group you should tie the tubes together. If you are also bringing a cooler, then you should also put the sunscreen in there. A few of my friends got a little sunburnt. When they rapids come, you need to hold on but keep your butt lifted. I was laying on my stomach on my tube and I put my feet down amd accident and I burned some skin on my foot on the rocks. It gets shallow in the rapids. Overall it was a really fun experience. I would do it again when if I go back to Arizona!
