National parks in Iowa

Iowa's six National Park Service units are not as dramatic as canyon or coastal parks. They offer active outdoor destinations and historically significant sites. Coralville Lake and DeSoto National Wildlife Refuge, located along the Missouri River, anchor the water-based activities. Three other sites trace the human story of the American interior. Effigy Mounds National Monument preserves Indigenous ceremonial earthworks above the Mississippi River. The Herbert Hoover National Historic Site in West Branch offers a quiet look at a presidential life. Both the Lewis and Clark and Mormon Pioneer trails cross the state. These trails serve as driving and hiking corridors, linking Iowa to larger continental journeys. Most units have multiple entry points for families with children. Iowa suits visitors who value depth over spectacle and appreciate having a trail largely to themselves.
