South Llano River State Park is a two thousand six hundred-acre Texas park in Kimble County along the South Llano River, opened to the public in nineteen ninety on land donated by Walter Buck Jr. Shaped by the property’s earlier use for goat and sheep ranching and pecan harvesting, it combines river, woodland, and open country. The park draws visitors for tubing, swimming, canoeing, kayaking, fishing, trails, camping, and dark-sky stargazing. It is especially valued for wildlife watching, with more than two hundred fifty bird species recorded, seasonal monarch butterflies and wild turkeys, nesting golden-cheeked warblers, and the endangered Tobusch fishhook cactus.
