Ky. To Grand Canyon on route I-40

There is a lot to see along I-40. In Amarillo, 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. 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 there is Petroglyph National Monument, the Pueblo Cultural Center, the Turquoise Trail and the Sandia Crest Highway that 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 Malpais National Conservation Area, 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.

Homolovi Ruins State Park is near Winslow where you can stand on the corner. Meteor Crater and Petrified Forest National Park are not far from the Arizona/New Mexico border.

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.

All this before you even get to the Grand Canyon.
