The two islands that make up Mille Lacs National Wildlife Refuge are closed to the public. Hennepin and Spirit islands are a sensitive breeding area for a variety of colony-nesting birds. If you are boating on Mille Lacs Lake, please stay at least 100 yards offshore while fishing or observing wildlife from your watercraft.
Location and Contact Information
Both Hennepin and Spirit islands are used by colonial nesting species, including ring-billed gulls, herring gulls, double-crested cormorants, American white pelicans and the state-threatened common tern. Mille Lacs National Wildlife Refuge hosts one of only five common tern breeding colonies in Minnesota. The common tern is currently listed as a state-threatened species, a Minnesota species in greatest conservation need, and a U.S. Fish and Wildlife Service conservation priority species.
