Follow the above one-week itinerary as far as Durango. From there, drive south to New Mexico and give yourself three days to explore Santa Fe, Albuquerque, and Taos. On your long drive west to Phoenix, be sure to drive over Route 66 for a bit of classic Americana (try to squeeze in the Petrified Forest National Park along the way). Spend your last two days in Phoenix and Scottsdale relaxing by an infinity pool or soothing achy hiking muscles at the spa.
