Frio County, Texas

Frio County lies in South Texas, where summers can be intensely hot. The name “Frio” means “cold” in Spanish, which feels almost amusing given the region’s scorching temperatures. The county actually takes its name from the Frio River, which flows through the area and provides an important natural feature in the landscape.

Pearsall serves as the county seat and sits along Interstate 35. Agriculture plays a major role in the local economy, with farmers growing peanuts, hay, and a variety of other crops. Winter vegetables are especially important, making the area a productive farming region even in the cooler months.

Frio County is also popular with hunters during deer season, when people head into the countryside in search of game. History remains visible as well, particularly at the old Frio County Jail, built in 1884. Today, the historic building serves as a museum and offers a glimpse into the county’s rougher early days.
