Visit October through early May to miss the stifling summer heat. Places like the Grand Canyon
and Monument Valley
, which are exceedingly popular in the summer, will be quieter in late spring or early fall. If your trip does fall during the summer months, the Mogollon Rim highlands
are a cool relief from the heat. Meanwhile, Flagstaff
is the perfect winter playground. If you have a winter road trip in mind, remember that snowy road closures are common at higher elevations. No matter when you visit, be prepared for cold nights everywhere in the state.
