Route 4 buses connect ALW with downtown Walla Walla
Valley Transit runs fixed-route bus service between Walla Walla Regional Airport (ALW) and downtown using Route 4, with stops along East Isaacs Avenue and near Main Street. This is the budget option if you’re local or staying in town and don’t want to pay for a taxi or rideshare. The airport sits about 4 miles from downtown, so ride time usually lands in the 10–15 minute range once the bus leaves the airport stop.
Service runs Monday through Friday only, generally from around 6:00 a.m. into the early evening, matching typical ALW flight windows. There is no weekend or late-night Valley Transit bus from the airport, so arrivals after the last early evening departure need a backup plan like a local cab. Always check the current Route 4 timetable on Valley Transit’s official site the same week you fly, because seasonal tweaks to first and last trips do happen.
Fares on Valley Transit stay low: a single adult ride is usually in the $1–$2 range, and day passes run just a few dollars more if you plan multiple trips beyond the airport–downtown hop. Pay with exact cash on board; there is no tap-to-pay reader or in-app ticketing on these buses in Walla Walla as of 2024. If you’re carrying checked luggage from Terminal 1, you can bring a standard suitcase and carry-on, but keep it compact so you’re not blocking the aisle.
The ALW stop sits outside the small Terminal 1 building, a short walk from baggage claim doors, so you’re curbside in under 2 minutes once you exit. Buses do not wait for late flights; Route 4 keeps to its city schedule, which might be every 30–60 minutes depending on time of day. Build a buffer if your inbound flight often runs late, and pull up real-time info or call Valley Transit’s main number before you leave home so you know exactly which departure you’re aiming for.
One last tip: if your hotel is on or near Main Street or Isaacs Avenue, check the specific Route 4 stop names and ask your driver which stop lands closest to your address; that quick question can save a 15–20 minute walk with bags after you get off the bus.
