Washington County Museum offers a gateway to the historical and cultural resources available in the Tualatin Valley and the western Portland Metro area at our two locations.
We offer many tour packages, special events, and activities for families, groups, and schools and classes to the museum. Our family events include Family Day events, Scout Passport Days, Birthday Parties, and Museum Camps during school breaks and summer.
We highly recommend using the TriMet Trip Planner for your visit to the museum or Research Library.
