Trails are occasionally closed due to wet conditions. Contact the park office for current trail status. Lake Red Rock and the Des Moines River provide great fishing opportunities. Elk Rock has two boat ramps, one located near the main park entrance and other is located by the park office. Bass, catfish, walleye and crappie are the most common fish caught in this area.
Fishing is also within walking distance of the campground.
Roberts Creek and Cordova Park, just north of Elk Rock, are popular fishing, boating and picnic spots. They are administered by the Marion County Conservation Board. Elk Rock State Park is located on Lake Red Rock, one of Iowa's large impoundments. The area had been inhabited by Native Americans dating back more than five thousand years to the Archaic Culture. In 1842, the Sac and Fox Indians granted white settlers right to this land.
