About Hays County Livestock Show and Expo

The Hays County Livestock Show and Expo in San Marcos is a September fair in the Texas Hill Country gateway city on the beautiful San Marcos River, celebrating the agricultural heritage of a county that bridges the Austin metro and the Hill Country while hosting Texas State University.

What to Expect

Expect livestock shows, FFA and 4-H competitions, carnival rides, local food vendors, and a community fair in the cedar hill country and river valley between Austin and San Antonio.

Visitor Tips

San Marcos is a River City gem — the crystal-clear San Marcos River for tubing and swimming, Texas State University, the outlet mall corridor, and the beautiful Wimberley area just to the west define the Hays County experience.
