Let the road set the pace.
Start your journey among giant saguaro cacti of the Sonoran desert and climb to shady conifer forests at nearly 9,000 feet, passing biological diversity equivalent to a drive from Mexico to Canada in just 27 miles. Enjoy spectacular views and recreational opportunities from hiking and camping to picnicking and skiing.

Before you drive
Make it a satisfying day
Choose a realistic section, then allow time for viewpoints, a town stop and breaks. Scenic mileage rarely tells the whole story of how long an outing will take.
Match the road to your vehicle
Check the exact roads for your car, RV or motorcoach. Tunnel dimensions, turning space, grades and road surfaces can matter as much as distance.
