The most helpful app to get around town via public transportation is TRANSIT. It’s offered for both iPhone and Android and it lists all the transit routes near you in real time. It’s very clear, accurate and helpful.
The MAX red line will get you from PDX International Airport to the conference hotel.
Fare: $2.50 for 2 ½ hours or day passes for $5.
Trimet day passes are also accepted on the Portland Streetcar which is helpful for getting around downtown and the inner Southeast.
The Portland Streetcar (A Loop and B Loop) both cross the Broadway Bridge and the Tilikum Crossing (Bridge of the People). The Tilikum Crossing is Portland’s new transit, cyclist and pedestrian only bridge. Both bridges are beautiful to walk across, and there are also waterfront walking/cycling paths along both east and west edges of the Willamette River.
BIKETOWN is Portland’s brand new bike sharing program. Day passes are $12. Riders can take multiple trips, but each trip must be under 3 hours. There are many hubs around downtown with bikes to borrow. See the website for maps and more information about how to join:
Here are pdfs of walking/cycling maps of each neighborhood in Portland with lots of great information and recommendations.
