This was one of the most fun adventures I've done in Phoenix. Our guide - Mark was experience, friendly and fun. He showed us the part of Desert which was absolutely beautiful.. Sonoran Outdoor Adventures provided us with brand new fat bikes, which were very comfortable. It was easy to ride them but at the same time it was a great exercise! We all enjoyed the fat bike tour. I would definitely recommend to everyone. Fat tire biking is a great way to get outside and explore the Desert in a whole new way. Super fun! Try it .You will love it !
