When the Fair Happens: Dates and Daily Hours

Mark your calendar now: the 2026 Washington County Fair in Hillsboro runs from Friday, July 24, 2026, at 9:00 am through Sunday, August 2, 2026, at 5:00 pm at Westside Commons. That’s a full ten days of festivities, giving families, friends, and fair fans plenty of opportunities to visit—whether you’re planning a single afternoon or multiple trips to catch different events and performances.

While the overall event window is set, daily operating hours at the fairgrounds typically stretch from daytime into late evening. Recent listings suggest hours such as weekdays from around 5:00 pm to midnight and weekends from about 10:00 am to midnight . For 2026, always double‑check the official schedule as the fair approaches, but you can confidently plan on long, lively days with plenty of time to explore rides, exhibits, and entertainment.

Where It All Happens: Westside Commons in Hillsboro

The fair takes place at Westside Commons (also known locally as the Washington County Fair Complex), located at 873 NE 34th Avenue, Hillsboro, OR 97124. Situated in the heart of Washington County, the site is designed to handle large crowds, livestock barns, exhibit halls, and the bustling carnival midway that defines a summer fair.

Because the fair regularly draws well over 100,000 attendees across its run, it’s wise to think ahead about transportation. Traffic on nearby routes like Cornell Road and Brookwood Parkway can back up during peak hours, and official parking lots often fill quickly on busy evenings and weekends. If you’d rather skip the congestion, consider arriving earlier in the day or exploring alternative parking options, including nearby lots and private driveways listed through services like Prked.

Arrive early at Westside Commons to beat traffic and secure closer parking.

What to Expect: Rides, Exhibits, and Free Admission

Once you’re through the gates, you’ll find all the hallmarks of a classic county fair. The Washington County Fair features amusement rides, livestock exhibits, motorsports, carnival games, 4‑H competitions, arts and crafts, and two stages of live entertainment showcasing regional and local talent . Around 30 food booths serve everything from corn dogs and funnel cakes to regional specialties, making it easy to turn your visit into a full‑day outing.

One of the fair’s biggest perks is that admission is free every day . That makes it an especially budget‑friendly option for families, who can decide how much to spend on rides, games, and food once inside. With the fair spanning two full weekends, you can easily return to catch different concerts, motorsports events, or 4‑H shows without paying another gate fee.

Planning Your Perfect Fair Day

To make the most of the fair’s dates, location, and generous hours, start by deciding what kind of experience you want. Early mornings and afternoons (especially on the second weekend) are ideal for families with young children who want to visit animal barns, explore 4‑H exhibits, and enjoy the midway before crowds build. Later evenings are perfect if you’re more interested in live music, bright midway lights, and a festive night‑out atmosphere.

Because the fair stretches from Friday, July 24 at 9:00 am through Sunday, August 2 at 5:00 pm, you can easily fit a visit into your summer schedule—even if weekends are busy. Pair the central Hillsboro location at 873 NE 34th Avenue with flexible, late‑running hours that extend into the night, and the Washington County Fair becomes one of the most accessible, fun, and affordable traditions on the Portland‑area summer calendar.
