Arizona's 25 Must-Visit Attractions

21 Visit Walnut Canyon National Monument

Walnut Canyon National Monument near Flagstaff has more Sinagua cliff dwellings to take in, and it's an hour away from Montezuma. Here, 25 rooms were abandoned seven-plus centuries ago. The Rim Trail is dog-friendly and wheelchair-accessible, but Island Trail is not. Walnut Canyon is a stunning destination worth adding to your Arizona itinerary.
