McKinney Roughs Nature Park is a 1,140-acre (460 ha) nature park and archaeological site in Cedar Creek, Texas, United States. Located about 13 mi (21 km) east of Austin and next to the Colorado River, the park features 17.6 mi (28.3 km) of trails for hiking, mountain biking, and horseback riding. The park is owned and managed by the Lower Colorado River Authority (LCRA). During the late Archaic Period, around 2,100 years ago, McKinney Roughs served as a camping ground for prehistoric hunter-gatherers. In the 1850s, the land was owned by a ranching family that were early settlers of Texas. Over the years, it passed through various owners until it was acquired by the LCRA, which then transformed it into a nature park in 1998.

The Lower Colorado River Authority (LCRA) is a nonprofit public utility created in November 1934 by the Texas Legislature. LCRA's mission is to enhance the lives of the Texans it serves through water stewardship, energy and community service. LCRA provides public power, manages the lower Colorado River, builds and operates transmission lines, owns public parks, and offers community services.
