About Lake Mille Lacs National Wildlife Refuge

Lake Mille Lacs National Wildlife Refuge protects critical habitat for migratory birds and native fish species on and around Minnesota's second-largest inland lake, offering excellent wildlife viewing and serene natural landscapes.

Wilderness Landscape & Natural Heritage

The Lake Mille Lacs National Wildlife Refuge is located in central Minnesota on the southeastern shore of Lake Mille Lacs, the state's second-largest inland lake. Covering approximately 2,000 acres of wetlands, islands, and shoreline habitat, the refuge was established in 1915 primarily to protect nesting habitats for waterfowl and other migratory birds. Its geographic setting includes a mix of shallow wetlands, emergent marshes, shrub swamps, and upland forested areas that support a diverse range of plant and animal species native to the upper Midwest. Key species that benefit from the refuge include common loons, bald eagles, osprey, and several species of ducks and shorebirds. The lake itself sustains a healthy fishery, with walleye, northern pike, and other game fish common in the area. Recreational opportunities here focus on wildlife observation, photography, birdwatching, and peaceful nature walks, with limited public access to ensure minimal disturbance to sensitive habitats. The refuge’s few walking trails and scenic viewing spots make it a popular destination during spring and fall migration seasons when bird activity is at its peak. Managed by the U.S. Fish and Wildlife Service, this refuge plays a critical role in preserving migratory bird corridors and native ecosystems, while providing quiet outdoor experiences for visitors. The surrounding Mille Lacs area offers additional recreational amenities, including fishing, boating, and camping, enhancing the overall visitor appeal.
