What to Know

Hillsboro is home to the Washington County Fair, which is one of Oregon's largest county fairs, drawing hundreds of thousands of visitors from the Portland metro for ten days of livestock competition, entertainment, and family fun. The fair began in 1951 and has remained a community tradition ever since.

Before You Go

Hillsboro is in the heart of the Silicon Forest tech corridor but also Oregon's top wine and berry growing area — buy advance tickets for top grandstand acts as they sell out quickly.

On the Midway

Expect championship livestock shows, 4-H and FFA competitions, a large carnival midway, major grandstand acts, local food and craft vendors, and the vibrant energy of Oregon's most populous county fair.
