A little bit of Texas hospitality in Williamson County goes a long way! It is one of the fastest growing counties in the country. Williamson Couny is a vibrant, self-sustaining community separated by I-35 into two distinctive regions: the Western Plains that fringe upon the Texas Hill Country and the Eastern Texas Blacklands, having rich, fertile, and clay-like soil, making it ideal for agriculture. From the hometown of the famous cowboy Bill Pickett in Taylor, the “Old Faithful” oil well in Thrall, the burial site of LeAnn the prehistoric woman, “Leanderthal Lady”, in Leander, Chisholm Trail, to the final shoot out of the infamous outlaw Sam Bass in Round Rock, Williamson County is rich in history and heritage.
