TriMet's Fare Zones

TriMet's service area is divided into three fare zones and a fare-free zone called Fareless Square. Adult fares are based on the number of zones you are traveling through. (Honored Citizen and Youth/Student fares are valid in all zones.)

Example: If you want to travel from Gresham Transit Center to downtown Portland, your trip would require an All-Zone fare, because you are traveling through all three fare zones.

What zone am I in?

You can find the exact zone boundaries on bus route maps, the MAX route map and the Interactive System Map. The Trip Planner automatically calculates the correct fare for you based on your origin and destination.
