Mason County, Texas

Mason County sits in the heart of the Texas Hill Country, where rolling hills and rugged landscapes create some truly beautiful scenery. The Llano River runs right through the county, adding even more charm to the countryside.

Mason serves as the county seat and has plenty of small-town character. Its historic sandstone courthouse stands proudly in the town square. The county is also famous for its topaz, the official state gem of Texas, and visitors can even try their luck searching for their own.

Ranching remains a major part of life here, with cattle and exotic game roaming the countryside. Spring brings colorful wildflowers across the hills, while clear nights offer an incredible view of the stars. With little light pollution, Mason County is a perfect place to enjoy the wide-open Texas sky.
