There a lot to see along I-40 between Amarillo and the Grand Canyon. As mentioned there is
Palo Duro Canyon State Park and the
Big Texan on Old Route 66.
In New Mexico,
Tucumcari still has dinners along Historic Route 66 and numerous murals painted on buildings plus other attractions like the foundry and dinosaur museum at the college. Santa Rosa is another Route 66 town and has the
The Blue Hole and
Santa Rosa Lake State Park which has a nice campground.
In Albuquerque, the
Pueblo Cultural Center and
Petroglyph National Monument are worth visiting in my opinion.
In Grants, there is the
Mining Museum. Just South of I-40 going West from Grants are
El Malpais National Monument,
El Moro National Monument and the
Ice Cave and Bandera Volcano.
Acoma Sky City is said to be the longest occuppied location in the U.S. They give tours of the pueblo and there is an RV park next to the casino.
On the way to Flagstaff along I-40 are
Petrified Forest National Park,
Meteor Crater and
Homolovi Ruins State Park. You can stand on the corner in
Winslow Arizona.
In the Flagstaff area are
Sunset Crater National Monument,
Wupatki National Monument, and
Walnut Canyon National Monument.
Sedona/Camp Verde/Cottonwood are about an hour South of Flagstaff with
Montezuma Castle and Montezuma Well National Monuments,
Tuzigoot National Monument,
Palatki and Honaki Ruins,
V-Bar-V Heritage Site,
Verde Canyon Railroad,
Fort Verde State Park,
Cathedral Rock,
Gold King Mine,
Jerome State Historic Park in the area. There is a nice campground at
Dead Horse Ranch State Park in Cottonwood.
All this before you even get to the Grand Canyon.
