Washington County Idaho Fairgrounds Events

The Washington County Fairgrounds serve the rural communities of Cambridge, Midvale, and Weiser in western Idaho. The annual Washington County Fair and Rodeo is the property’s main public event, bringing together agricultural exhibitors, 4-H families, livestock owners, local businesses, and visitors from across the county.

Cambridge, the county seat, sits along U.S. Highway 95, roughly 100 miles northwest of Boise by road. The fair is closely connected to the area’s agricultural economy, where cattle ranching, hay production, and other rural livelihoods remain important. For local young people, fair week is also a chance to show the results of months of work on livestock, gardening, crafts, and other educational projects.

Washington County lists the fairgrounds’ physical address as 115 East Central Boulevard, Cambridge, Idaho 83610. Because the address also serves as the county’s fair contact location, visitors attending a specific event should confirm the public entrance and parking instructions in the current fair announcement.

The fair is coordinated by the Washington County Fair Board, with support from the county and University of Idaho Extension’s Washington County 4-H program. The fair organization describes its work as preserving local agricultural traditions, supporting youth education, and providing a place for community exhibits and entertainment.

A detailed, verified acreage figure and a complete inventory of permanent buildings were not available in the county information reviewed. The grounds are used for fair exhibits and livestock-related activities, while the wider property is also available for approved private rentals and dry camping.

Upcoming Events at Washington County Fairgrounds

The annual Washington County Fair and Rodeo

The annual fair is the central event on the local fairgrounds calendar. It combines livestock and youth exhibitions with rodeo entertainment and other fair-week activities. The exact daily schedule can change, so visitors should distinguish confirmed events from activities that are simply common at county fairs.

Confirmed 2027 fair dates

The Washington County Fair’s published schedule lists July 25–31, 2027 for the next fair. The detailed timetable for individual competitions, rodeo performances, vendor hours, and any additional entertainment should be checked closer to the event.

As of October 2026, no separate confirmed list of recurring monthly public events was available for the Cambridge grounds. People searching for upcoming events in Washington County, Idaho, should check the county’s fair announcements and event calendar rather than relying on listings for Washington County fairs in other states.

Other events and facility rentals

The fairgrounds are available for approved private and community occasions, including weddings, family reunions, funerals, meetings, and other gatherings. Rental arrangements can include tables and chairs, depending on the agreement. Dry camping and winter RV storage are also listed as separate services.

Livestock shows, 4-H activities, rodeo events, and open-class exhibits are closely associated with fair week. Gun shows, flea markets, demolition derbies, tractor pulls, motocross events, and seasonal festivals should not be treated as scheduled events unless the organizers specifically announce them.

For current event information, contact the fair manager or the county’s fair board. University of Idaho Extension is the best starting point for 4-H enrollment and youth project questions.

The County Fair: Exhibits, Rodeo, and Youth Competitions

Typical Fair Week: Late July

Washington County Fair week takes place in late July. The confirmed dates for 2027 are July 25–31. The fair book and daily program are the best references for specific livestock check-in times, exhibit judging, rodeo performances, and special activities.

Livestock and open-class exhibits

The fair’s agricultural focus includes youth livestock projects and open-class entries. Depending on the approved divisions for the year, participants may enter animal projects, produce, field crops, flowers, baking, food preservation, needlework, photography, woodworking, crafts, and other handmade or agricultural exhibits.

The fair’s 2025 fair-book rules stated that open-class entries could be submitted online, with check-in on Monday and Tuesday during fair week and open-class judging on Wednesday morning. These are useful indicators of how the program has worked, but exhibitors should confirm the corresponding 2027 instructions before preparing entries.

Rodeo, food, and family entertainment

Rodeo is a major part of the Washington County Fair and Rodeo identity. Livestock judging and youth activities provide the agricultural side of the week, while food booths, commercial displays, and other entertainment create reasons for the wider community to attend.

The current number of carnival rides, wristband prices, specific musical performers, and any demolition derby or tractor-pull program were not confirmed. Check the current schedule rather than assuming these attractions will be included every year.

Admission and parking

The 2027 admission prices and parking arrangements were not confirmed in the available information. Visitors should check the current fair announcement for gate charges, rodeo tickets, discounts, and parking instructions. Older prices should not be treated as current.

Facilities and Grounds

Buildings and event spaces

The Washington County Fairgrounds can be rented for community and private functions. The county’s rental information states that standard rentals include 30 rectangular tables, 24 round tables, and 300 chairs. Availability and the exact spaces included depend on the rental agreement.

The grounds are used for fair exhibits and livestock-related activities, but a complete, current building-by-building inventory and verified arena seating capacity were not available. Organizers should confirm which indoor or outdoor spaces are suitable for a proposed event.

Camping and RV storage

The county lists dry camping at the fairgrounds for a separate fee, along with winter RV storage rentals. Dry camping should not be confused with full-hookup RV sites: visitors should ask whether electricity, water, restrooms, waste disposal, and overnight access are provided for their dates.

For camping, storage, or facility rental questions, contact the fair manager at 208-257-3773 or [email protected].

Parking, accessibility, and amenities

Parking arrangements may differ between ordinary rental events and crowded fair days. Ask about designated accessible parking, accessible restrooms, building access, livestock-trailer parking, and any overflow arrangements before traveling. The county’s published information does not establish a current total parking capacity or confirm the availability of on-site ATMs, first-aid stations, or concession facilities throughout the year.

Vendor and Exhibitor Information

Commercial vendors and food booths

Businesses interested in selling products or serving food during the Washington County Fair should contact the fair manager for the current vendor application. Ask about booth availability, fees, setup and teardown times, electrical needs, insurance, food permits, and any restrictions on merchandise or cooking equipment.

Do not rely on a previous year’s fee schedule unless the fair board confirms that it remains valid for the 2027 fair.

Entering open-class exhibits

Open-class participants should review the current fair book for categories, entry deadlines, check-in procedures, and judging rules. Washington County has provided an online enrollment system for open-class entries, but the correct process and dates should be checked for the relevant year.

Livestock exhibitors need to confirm their class requirements, animal identification and health documentation, check-in windows, and any weigh-in or showmanship rules before arriving.

Getting to Washington County Fairgrounds

Driving directions

The fairgrounds are in Cambridge, the county seat of Washington County, in western Idaho.

• From downtown Cambridge: Follow local streets toward East Central Boulevard and confirm the event entrance before arriving.
• From Weiser: Travel east toward Cambridge on U.S. Highway 95, the principal route connecting the county’s western communities with its county seat.
• From Midvale: Follow the local road network toward Cambridge and connect with U.S. Highway 95 as appropriate for your starting point.
• From Boise: Take the route toward western Idaho and U.S. Highway 95 north to Cambridge. Allow additional time for rural highway travel and summer traffic.

The fairground contact address is 115 East Central Boulevard, Cambridge, ID 83610. Visitors towing livestock trailers or bringing large vehicles should confirm the correct entrance and parking instructions in advance.

Public transportation and rideshare

Regular public transportation or a dedicated fair-week shuttle was not confirmed. Visitors should arrange their own transportation unless the organizers announce a shuttle or special parking service. Rideshare availability may be limited in a rural community such as Cambridge, particularly late in the evening, so arranging a return trip ahead of time is sensible.

4-H and FFA at Washington County Fairgrounds

University of Idaho Extension and youth projects

University of Idaho Extension in Washington County supports agriculture, livestock education, horticulture, and 4-H youth development. Its office is located at 116 West Idaho Street, Weiser, Idaho 83672, and can be reached at 208-414-0415.

For families interested in participating in the Washington County Fair, Extension can help explain enrollment, project selection, and youth program requirements. The fair organization also identifies 4-H, FFA, and other community groups as part of its mission, although a current verified count of active clubs and participating FFA chapters was not available.

Junior livestock and buyer participation

Youth livestock projects can involve preparing animals, learning feeding and care routines, practicing showmanship, and presenting animals for judging. A market-animal sale or buyer-supported program may form part of the annual fair schedule, but exhibitors and potential buyers should confirm the exact 2027 arrangements.

The fair’s published information has recognized leading livestock-sale buyers, including area ranching and agricultural businesses. Anyone interested in bidding or supporting a young exhibitor should ask the fair board about sale eligibility, bidding procedures, payment terms, and whether additional contributions are permitted.

Special Events Beyond the Annual Fair

The annual Washington County Fair and Rodeo is the best-established recurring attraction at the Cambridge grounds. The property is also available for private gatherings, meetings, and other approved uses.

Weddings, family reunions, funerals, and meetings are specifically listed among rental uses. Dry camping and winter RV storage provide additional services, subject to availability and the applicable agreement.

Visitors looking for a swap meet, flea market, gun show, motocross competition, tractor pull, or touring concert should verify the event directly with the organizers. An event held elsewhere in Washington County—or at a Washington County fairground in another state—is not necessarily associated with the Cambridge property.

History of Washington County Fairgrounds

Washington County’s agricultural identity developed around the rural communities of Cambridge, Midvale, and Weiser. Livestock production, farming, and ranching remain relevant to local life, and the county fair provides a public setting for agricultural education and youth achievement.

The Washington County Fair organization describes itself as a community-driven nonprofit supported by volunteers, board members, exhibitors, and local supporters. Its role extends beyond entertainment: fair activities allow young people to demonstrate practical skills and give residents an opportunity to display local products, crafts, and agricultural work.

A precise establishment date for the current fairgrounds, a complete history of the annual fair, and verified records of major attendance years or past cancellations were not available in the current county information. Those details should be confirmed through county records or local historical archives rather than guessed.
