From the Portland Airport, take the RED MAX train (it’s the only one that goes to the airport) toward downtown Portland.
Switch to the BLUE MAX train to get into Hillsboro (switch anywhere in Portland –Pioneer Square or Beaverton Transit Center is probably best because it is the end of the RED line).
If staying at the hotels listed below, get off the MAX at the Orenco Station. It is an approximate 1 mile to each hotel.
Hotels in Hillsboro:
There are many hotels in the area, but the two hotels listed have a shuttle that will take you to the MAX station and/or will take you to the Pacific Hillsboro campus, which is within the 5 miles radius.
