This road trip is a once in a lifetime and shows you the best of Northern Arizona and Southern Utah while minimizing drive times! I'd recommend flying into St George, Utah (or Las Vegas, NV but the drive to Springdale near Zion National Park will be longer on your first day) and flying out of Phoenix, Arizona airport.
If you’re coming from out of town, consider adding an extra day before and after the planned itinerary since each day is packed with activities.
