Four Corners is the only place in the United States where you can stand in four states at once. This is where Utah, Colorado, Arizona and New Mexico meet. If it is crowded, you may have to wait in line for your photo op. The spot is actually on a Navajo indian reservation. There were warning signs about theft etc, but we didn't have a problem. Around the outer perimeter of the area, they have booths where the Navajos sell their crafts. Turquoise is a big thing in New Mexico, so you can by Turquoise jewelry etc. We were probably in and out of here in a little over an hour. We were able to stop at Four Corners, tour Antelope Slot Canyon and enjoy the scenic drive through Monument Valley all in one day on the way from Mesa Verde to the Grand Canyon.
