Inner Basin Trail, Coconino National Forest, Flagstaff

The Flagstaff fall foliage show usually begins in late September on the Inner Basin Trail.  Plan ahead and be prepared for crowds if you want to stroll among tight-knit aspen groves high on the eastern flanks of the San Francisco Peaks. Getting to this immensely popular trail involves a white-knuckle drive on a sinuous, edgy dirt road, but for those who dare to brave the congestion and hairpin turns, the hike is one to savor.
