As of yesterday, you can reserve a campsite for any of Iowa’s state parks, including Guthrie County’s Springbrook State Park for Memorial Day weekend. The Department of Natural Resources says that while electric campsites usually go quickly, most parks will have non electric sites available up until Memorial Day weekend. The DNR says parks may maintain 25% to 50% of their sites as non-reservation sites, available for walk up camping. To make your reservation, you can log onto www.iowastateparks.reserveamerica.com .
