McMullen County, Texas

McMullen County is tucked away in South Texas, roughly halfway between San Antonio and Corpus Christi. It may have a tiny population, but it’s full of character. Ranching is a major part of life here, with oil and gas also playing an important role in the local economy.

The landscape is rugged and scenic, covered in brush, rolling hills, and wide-open stretches of countryside. Tilden serves as the county seat and is a very small community, but its residents are known for their warm, welcoming nature.

Hunting is a favorite pastime, especially for deer and quail. Life moves at a slower pace here, where neighbors know one another and traffic is hardly an issue. No crowded roads or rush-hour chaos—just peaceful ranch country beneath a huge Texas sky.
