This nature park contains historic and pre-historic artifacts. Found on the grounds are remnants of a waterworks on Mill Creek, the homestead of Edmond E. Risien, father of the thin shell pecan, a mature pecan orchard, and numerous locations containing artifacts of early Native American habitation.

A fully accessible paved trail system connects various points of interest within the park including an entry plaza and restroom structure, a cantilevered overlook of the old Mill Creek Waterworks, two pedestrian bridges over Mill Creek, a wildlife observation structure, and a paved fishing area on the San Saba River, and several interpretative areas detailing the features and history of the site.
