Visit the Refuge

Explore the great outdoors and diversity of wildlife at any one of 17 units within the Big Muddy National Fish and Wildlife Refuge. From hiking trails, observation decks, to hunting opportunities, there's plenty to enjoy. Exhibits at the Refuge visitor contact station tell the story of the Missouri floodplain and river habitats, and is open from 7:30 a.m. to 4:00 p.m., Monday through Friday, except on federal holidays, during inclement weather, or when staff are out for field work. Visitors are recommended to give us a call ahead of time to ensure that there will be a staff member or volunteer present to assist you.
