River Island State Park was full when we checked in and they offered us overflow camping instead until a hook up site became available. Very affordable at only $20 a night with a noon checkout time. Very clean Park with flush restrooms,showers,dump stations,fresh potable water places around the park. Hiking trail overlooking Park and beach area for swimming and fishing. Gas station/ convenient store half mile up road,with free air and grill (burgers,pizza). Prices were amazing!
