We like to do a little off-roading in Colorado in our Jeep. The roads taken include Kebler Pass and Paradise Divide near Crested Butte, Boreas Pass in Breckenridge and Cinnamon Pass from Lake City to Silverton. These are certainly not the toughest trails, but they do include their share of bumps, narrowness, shelf roads and so on. Most recently we drove Last Dollar Road from Telluride to the Ridgeway road.
Last Dollar Road we named as an alternative to Million Dollar Highway from Silverton to Ouray. It is 13 miles long, very scenic, and runs through stretches of ranchlands and the San Juan Mountains. On the south end it offers spectacular vistas including Mt. Wilson. The drive almost requires four wheel drive in sections, and takes about 2-3 hours. The drive is particularly attractive in the summer wildflower season and during the fall color changes in the aspen groves along much of the road.
The Telluride-Ridgeway-Ouray area offers many other off road adventures, including Imogene Pass, Yankee Boy, Ophir pass and so on. These tend to be somewhat more challenging, and definitely require four wheel capability. Down the road for us!
