Fantastic experience. Ron was our tour guide and went the distance to create a great day. Can't thank him enough. My advice, bottom line: Just do it. Pull the trigger and sign up. You'll be glad for it. I was traveling through with limited time in the Moab area so decided to rely on a tour to get the best experience for both Arches and Canyonlands. I would not have seen the incredible places Ron took us without being on that tour. All the tour guides do their best to provide great experiences. The full day tour that I purchased provides lunch, plenty of water refills and lots of good snacks. To have someone else do the driving and show you around while you focus on the sights and take all the pictures your camera can manage. Wear good walking/trail shoes, a hat, and bring your personal water bottle for refills.
