Grand Mesa Scenic and Historic Byway, Colorado
During the fall, Colorado's landscape becomes a tapestry of colors. The popular Aspen trees turn golden hues in September, and one of the best spots to witness this transformation is from the world's largest flat-top mountain. You can reach it by taking the 63-mile Grand Mesa Scenic and Historic Byway, which begins off route 70 and passes by lakes, fields of wildflowers, narrow canyons, and evergreen forests.
