Visas & entry
Arizona follows United States entry rules. Citizens of Visa Waiver Program countries generally need an approved ESTA before air or sea travel; other travelers generally need the appropriate U.S. visa. Requirements can change, so verify with U.S. Customs and Border Protection or the relevant U.S. consulate before travel.
Getting in
- Phoenix Sky Harbor International Airport: The dominant gateway for first-time Arizona road trips, with the broadest flight network and easy access to Phoenix, Sedona and the Grand Canyon circuit. Pick up a rental car here unless staying entirely in central Phoenix or Scottsdale.
- Tucson International Airport: Best for a Tucson, Saguaro National Park, Bisbee, Tombstone and southeastern Arizona trip; it avoids an unnecessary Phoenix backtrack on a southern loop.
- Flagstaff Pulliam Airport: Useful only when its limited schedules and fares work for you. It is close to Flagstaff and the high country, but Phoenix is usually the more practical and cheaper car-rental gateway.
- Flagstaff Amtrak station: The Southwest Chief serves Flagstaff for rail travelers, but onward travel to the Grand Canyon, Sedona, Page and trailheads still requires a rental car or arranged tour.
- Tucson Amtrak station: Southern Arizona is served by the Sunset Limited/Texas Eagle corridor, but rail is not a substitute for a car outside the city.
Getting around
Rent a car for any itinerary beyond Phoenix or Tucson: it is effectively essential for trailheads, canyon viewpoints, tribal parks and small towns. Phoenix and Tucson have local transit, while Amtrak serves limited northern and southern corridors, but neither solves the geography of a road trip. Check AZ511 during winter storms and monsoon weather rather than trusting navigation apps; high-country roads can close, and slot-canyon country needs weather-aware timing.
Money
The U.S. dollar is used throughout Arizona. Cards are widely accepted in cities, hotels and national parks, but carry some cash for tips, small rural businesses and occasional tribal-land purchases. Tipping is customary: roughly 18–22% in full-service restaurants, plus tips for guides, drivers and hotel staff.
Book before you land
Antelope Canyon guided tour, especially popular morning and photography-oriented departures · Navajo-guided Monument Valley tours, particularly sunrise, sunset and photography tours · Canyon de Chelly canyon-floor tours with authorized Navajo guides · Grand Canyon South Rim lodging and developed campgrounds · Grand Canyon backcountry permits for below-rim overnight hikes · Popular rafting trips and guided Colorado River experiences
- Do not underestimate Arizona distances: Phoenix–Sedona is about two hours, Flagstaff–Grand Canyon South Rim about 1.5 hours, and Monument Valley–Phoenix about 6.5–7.5 hours without sightseeing stops.
- Start low-desert hikes at dawn from late spring through early autumn; heat illness is a real risk, not a toughness test.
- On Navajo Nation lands, follow local rules on permits, guides, photography and access. These are living communities and sovereign tribal lands, not open-access theme parks.
- Antelope Canyon is guide-only, and flash floods can be deadly even when rain is not falling where you stand.
- For a South Rim visit, sleep at the rim or in Tusayan if sunrise and sunset matter; Flagstaff is workable but not an effortless same-day base.
- The South Rim is the dependable year-round Grand Canyon choice. Check North Rim operating status directly before booking, especially in late autumn, winter and after severe weather.
