Fall colors at their finest. See the largest grove of aspens on earth. Avoid the crowds (sorf of).
Kebler Pass, or Gunnison County Road (GCR) 12, is an excellent place to see fall colors in Colorado. You won't get nearly as much congestion as on Independence Pass in Aspen, but you get just as many yellow and amber leaves. The road is dirt but passable by any vehicle–although because it's at over 10,000 feet–it's closed in winter and can get extremely muddy if it snows or rains. The mud is slick. You'll want a 4WD vehicle, and boots for all weather if you're going to be stopping along the way to take photos.
Your jaw will start dropping as you take McClure Pass, just after the small town of Redstone. Follow 133 all the way over and just past Paonia State Park. You'll take a left on GCR 12 for 30 miles of incredible views, winding up right in downtown Crested Butte.
