The park was created in 1966, and contains 1,400 acres.{{cite web|publisher=Shop Oklahoma |title=Walnut Creek State Park |url=http://www.shopoklahoma.com/walnutcr.htm}} Facilities include sandy beaches, a softball field, picnic shelter with tables, RV hookups, and tent sites and restrooms. The {{convert|15|mi|km}} long Sand Plum Trail is open to hikers, horseback riders, and mountain bikers. The park has an equestrian campground, but visitors must bring their own horses because horses are not available for rent in the park.{{cite web |url=http://www.ohranger.com/ok/walnut-creek |publisher=Oh Ranger! |title=Walnut Creek State Park}}{{cite web |title=Walnut Creek State Park |publisher=Oklahoma Tourism and Recreation Department |url=http://www.travelok.com/listings/view.profile/id.8380 |access-date=January 6, 2013}} The park was open all year.{{cite web |title=Walnut Creek State Park |url=http://www.keystoneok.com/walnut/index.htm |publisher=Keystone OK}}
