Knob Noster State Park is a tranquil retreat of open oak woodland with a few patches of prairie along both sides of the meandering Clearfork Creek. It’s a place for fishermen to wet a line, for mountain bikers, hikers and horseback riders to get some trail time, and for families to spend quality time together. The park also features an oxbow slough, which has been officially designated as Pin Oak Slough Natural Area.
