The park borders the Red Rock Dam, which was constructed by the U.S. Army Corps of Engineers for flood control on the Des Moines River.
The area surrounding the park is a known wintering ground for bald eagles, which congregate near the open water below the dam.
The park contains remnants of coal mining history, which was a significant industry in the Knoxville area during the early 20th century.
The equestrian trails at Elk Rock are some of the few designated horse-friendly paths maintained within the Iowa State Park system.
Lake Red Rock, managed by the Corps of Engineers, encompasses over 15,000 acres of water surface area.
Elk Rock State Park is situated on the shores of Lake Red Rock, Iowa's largest reservoir. The park covers over 1,300 acres of terrain, featuring a mix of hardwood forests, restored prairies, and meadows. It serves as a primary access point for fishing, boating, and equestrian activities on the lake. The park is divided into two distinct tracts separated by the lake: the main park area and the quieter, more rugged North Overlook. Over 13 miles of multi-use trails accommodate hikers, mountain bikers, and horseback riders. The facility provides modern and primitive camping sites, including areas specifically designed for equestrian campers. Wildlife viewing is prevalent, with regular sightings of bald eagles, white-tailed deer, and wild turkeys. It is managed by the Iowa Department of Natural Resources to preserve native ecosystems while providing recreational water access.
The elevated outlook points facing the main body of Lake Red Rock during sunset.
Bring binoculars if visiting in winter to view bald eagles near the dam spillway.
Check the U.S. Army Corps of Engineers website for current water levels, as high water can occasionally submerge low-lying trails.
If camping with horses, ensure you reserve the specific equestrian-designated sites well in advance.
Do not attempt to hike near the base of the dam or restricted spillway areas during water release events.
Camping areas may have restricted availability during late autumn and winter months; check for seasonal water shut-offs.
Stay on marked trails to protect restored prairie habitats and respect wildlife distance protocols.
