Most of old Rt. 66 exists as business rt. frontage to towns along I- 40.This is where you'll see carcasses of old motor lodges, restaurants, and old buildings. A nice stretch runs from just past Needles, CA through Oatman AZ to Kingman. It's a nice stretch to drive by car but a bear if you are over 40 feet. Oatman is a cute old town and many old mines are along this stretch. like.We stayed in Flagstaff for our road trip to the Grand Canyon. Then you can drop south to Sedona if you like. Santa Fe Plaza is a great place to people watch and visit street vendors and gift shops as well as view old Spanish architecture.
