Established in 1937, Swan Lake National Wildlife Refuge covers 10,795 acres two miles south of Sumner, near the confluence of the Grand and Missouri rivers.
Wildlife observation is the most popular activity, especially driving through the refuge in the evenings. The bird list at Swan Lake includes 241 species.
There are large populations of ducks, coots and geese. Also, the refuge is one of the best places in Missouri to observe bald eagles, with the numbers peaking near 100 during the winter months. The Visitor Center includes videos and exhibits. Hike the nature trail; photograph wildlife; hunt deer and geese (in season); and go fishing (Missouri regulations apply).
The refuge is open during daylight hours only. The interior of the refuge is closed early November to early March.
