“The Hottest Little Fair in California is a Gold Country Keepsake” The Mother Lode Fair is located in the beautiful foothill town of Sonora on historic State Route 49. The Fair began in 1889 as the Tuolumne County Fair & Horse Show, then reinvented itself in 1938 as the Mother Lode Fair.

The Fair today is situated on 25 acres, edged with lawns and bordered with a year-round creek. Two hundred trees add scenic value to this garden setting, making the fairgrounds an event destination to an estimated 274,000 visitors throughout the year. The Mother Lode Fair provides our community event programming and a facility that enhances the quality of life in Tuolumne County.
