For me, the highlight of the fall is the mountain biking. Not only is it a little cooler and the trails less crowded, but there also tends to be more participation in the fall, which, when that moisture is absorbed into the dirt, makes the trails grippier. That being said, the changing colors of the leaves are a close second. Nothing, besides snow of course, serves as a better reminder of the impending winter than watching the Aspen trees’ leaves change from green to yellow and then eventually fall to the ground.
Fall is also an excellent time to visit southern Utah. With five National Parks, Arches, Bryce Canyon, Canyonlands, Capitol Reef, and Zion, you can explore a huge variety of natural beauty in a limited amount of time and not get fried by the sun. Additionally, Moab, UT, and Fruita, CO, offer some of the best desert mountain biking around.
