Visit Portland without renting a car! Tri-Met is the Portland metro public transit agency. You can take MAX Light Rail from the Portland International Airport to the Beaverton Transit Center, and then use Lyft or Uber to get around during your stay. Use MAX to easily visit downtown Portland, as well. There is also a transit center at Washington Square Mall. More info at www.trimet.org. If renting a car, know that car rental companies are located within the airport.
