Portland Buses, operated by TriMet, are an efficient, inexpensive way to see Portland. The drivers are friendly and helpful and Portland riders almost always offer a loud “thank you” when exiting at their stop. Must be a Portland thing.
An all-day ticket is $5 for adults and $2.50 for Honored Citizens, the name given to Senior Citizens 65 years or older.
You can hop-on, hop-off as much as you like, using paper tickets, the TriMet App on your smartphone, or a HopCard, and transfer between the buses, Max light rail, and Portland Streetcars.
Buses crisscross downtown near Pioneer Courthouse Square making it easy find a bus to take you within easy walking distance of all the best tourist spots.
