When Not to Go
For a statewide excursion, keep in mind that Arizona's climate is extreme. Although a winter visit might be most comfortable in Phoenix, remember that the Grand Canyon, Flagstaff, and Sedona—Arizona's high country—will be quite cold then. Also take note that areas such as eastern Arizona are most popular with summer travelers, so many shops and restaurants are closed in the winter months. Remember that the North Rim of the Grand Canyon is closed in winter, from mid-October to mid-May.
