About Harding County Fair

The Harding County Fair in Mosquero celebrates one of New Mexico's least populous counties in the northeastern corner of the state, where the Canadian River's tributary canyons cut through the high plains and cattle ranching has sustained small communities in a vast, semi-arid landscape since the late 19th century.

What to Expect

Expect livestock shows, 4-H competitions, rodeo events, and the genuine small-county community spirit of one of the most remote counties in the American Southwest, where ranching families travel long distances to attend the annual fair.

Visitor Tips

Mosquero is one of New Mexico's smallest county seats. Harding County's vast rangelands and the Canadian River canyon country are among the least visited landscapes in the Southwest, and the county's remoteness preserves a way of ranching life little changed from the territorial era.
