Sky Harbor: Your Starting Point
Phoenix Sky Harbor International Airport sits just southeast of downtown, which makes it one of the more centrally located major airports in the country. That location is a real advantage once you're settled in -- most of the metro's core destinations sit a short drive or transit ride from that central point rather than the 45-minute slog you'd get from a lot of other major-city airports.
For everything about the airport itself -- which terminal your airline uses, how the free PHX Sky Train works, the Rental Car Center, where rideshare actually picks up, and real drive times into the Valley -- see our full Sky Harbor Airport Guide, the arrival authority for this site. Once you're out of the airport, here's how to keep moving around the rest of the Valley.
Valley Metro Light Rail and Buses
Valley Metro light rail now runs two lines that meet at a downtown transfer hub: the A Line runs east-west connecting Phoenix, Tempe, and Mesa, passing through downtown Phoenix and ASU's Tempe campus along the way, and the B Line, which opened in 2025, runs north-south through downtown and South Phoenix. You can plan connecting bus service for legs off either line using Valley Metro's trip planner. It is a genuinely useful option if your trip stays within the downtown-Tempe-Mesa corridor or the South Phoenix extension, and fares are affordable relative to parking and rideshare costs.
Where light rail falls short is coverage. It does not reach Camelback Corridor, Old Town Scottsdale, north Phoenix, South Mountain, or most of the sprawl that fans out from the central corridor-which is most of the metro area by land. Valley Metro also operates local and express bus routes that extend reach somewhat, but bus frequency and coverage vary a lot by route, so check current schedules and trip-planning tools on the Valley Metro site before relying on buses for anything time-sensitive, like an early flight or a timed tour reservation.
Rental Cars and the Freeway Grid
For most visitors covering more than the downtown-Tempe core, a rental car is the practical choice. Phoenix is organized around a loop-and-spoke freeway system: I-10 runs east-west through the heart of the metro (and continues toward Tucson to the southeast), I-17 runs north out of the city toward Flagstaff, and SR-51 (the Piestewa Freeway) connects central Phoenix to the north-central neighborhoods. Loop 101 and Loop 202 form a broad ring around the metro area, while Loop 303 extends that ring further west, and these loops are what make cross-town trips between, say, Desert Ridge and South Mountain manageable without cutting through downtown surface streets.
Phoenix's surface street grid is also unusually easy to navigate once you understand it: most major roads run in a strict north-south or east-west grid, spaced roughly a mile apart, which makes mental map-building simpler than in older, less regular cities. That grid logic is genuinely helpful when you're stringing together stops from our things to do in Phoenix guide or building your own 3-day itinerary, since distances between neighborhoods are more predictable than they look on a map.
Rideshare, Taxis, and When They Make Sense
Uber and Lyft operate throughout the Valley and are a reasonable substitute for a rental car if your trip is concentrated in one or two areas-say, a downtown stay with a couple of dinners in the Camelback Corridor. Airport pickup zones exist at Sky Harbor for rideshare and taxi, though exact staging locations shift periodically, so follow the airport's current signage or app instructions rather than relying on last trip's memory.
Rideshare gets expensive fast if you're covering long distances daily, which is common in Phoenix given how far apart neighborhoods sit. If your itinerary includes multiple day trips or hikes at trailheads without reliable rideshare pickup, a rental car will almost always work out cheaper and more flexible over a multi-day stay.
Biking, Walking, and Parking Realities
Downtown Phoenix, Roosevelt Row, Tempe near ASU, and Old Town Scottsdale are the most walkable pockets in the Valley, each dense enough to cover on foot once you're there. Outside those areas, walking between attractions generally is not realistic-distances are long, summer heat makes daytime walking genuinely risky for months at a time, and much of the city was built assuming a car for every trip.
Biking has more going for it than most visitors expect: the Valley has an expanding network of bike lanes and multi-use paths, including the Grand Canalscape and the Tempe Town Lake loop, and dockless bike share (currently Grid Bikes, powered by HOPR) operates in parts of downtown Phoenix, with coverage elsewhere in the Valley shifting over time-check the current app for real-time availability near you. Parking, meanwhile, is rarely a major obstacle-most hotels outside the densest parts of downtown offer on-site parking, and popular trailheads like those on Camelback Mountain are the main exception, where lots fill early and you should plan around that rather than around downtown parking scarcity.
Putting a Route Together
A reasonable default for most trips: rely on Sky Train and light rail for the airport-to-downtown or airport-to-Tempe leg if that's where you're staying, then rent a car for a day or two to cover hiking, north Phoenix, and any day trips you have planned. If your whole trip stays within the light rail corridor and you're not hiking or leaving the city, you can likely skip the rental car altogether and lean on rideshare for the gaps.
If you're renting only for part of your stay, book the car for the days you actually need it rather than the whole trip-many visitors pick up a rental the morning they plan to hike or head out of town and return it a day or two later, saving on both the rental cost and downtown parking fees in the interim. Whatever mix you land on, build a little slack into your timing: freeway congestion during weekday rush hours and trailhead parking crunches on weekend mornings are the two most common ways a Phoenix schedule slips.
