The Bonneville County Fairgrounds has grown alongside the community it serves. When the former grounds on Rollandet could no longer meet the county’s need, the Fair Board acquired 50 acres in 2017. After years of fundraising, planning, and hard work, the first 4-H fair was held at the new location in 2019.
That move gave us room to do more. Today, the fairgrounds is a place for youth to learn and compete, families to gather, and neighbors to share in Bonneville County’s agricultural traditions. The county fair and 4-H remain an important part of our story, alongside open shows, equine events, community gatherings, and activities throughout the year.
The fairgrounds continues to grow because people care enough to give their time, resources, and ideas. The Fair Board is working to build on that commitment: caring for the grounds, welcoming new opportunities, and creating a place where more people can participate and belong.
The Bonneville County Fair provides educational avenues for youth and Bonneville County residents to acquire knowledge, develop life skills and form attitudes and relationships that will enable them to be contributing members of society.
The Bonneville County Fairgrounds is run by a board of volunteers appointed by the County Commissioners. The Fair Board works tirelessly to maintain and improve the Fairgrounds and have turned it into a real community hub. The facilities are utilized for all kinds of events and activities and it is rare to drive by and find the parking lots empty these days. We truly appreciate all the help the community offers to make these Fairgrounds one of the best around.
If you’d like to get involved we’d love your help!
