The 11,500 acre Big Stone National Wildlife Refuge lies within the heart of the historic tallgrass prairie. A drive along Minnesota’s Scenic Highway 7 provides a glimpse of wildflowers like yellow coneflower and leadplant, and grasses such as big bluestem and prairie dropseed. These plant species are components of the Refuge’s 1,700 acres of remnant tallgrass prairie.

The Refuge features car and bike tour routes and foot trails. During the summer months visitors have the opportunity to view bison grazing on restored prairie within the auto tour route. Hiking the granite outcroppings along the Minnesota River provides ventures into plant, stone, and wildlife study. The only population of ball cactus in Minnesota can be readily found in this area.

Big Stone Refuge boasts over 260 bird species that utilize the Refuge’s grassland and wetland habitats. The Refuge serves as a major migratory stopover for more than 20 species of waterfowl and 30 species of shorebirds. The highest concentrations of some shorebird species in the state of Minnesota and in the prairie potholes can be found on the Refuge. Bald Eagles have successfully raised 2-3 eaglets every year on the Refuge since 1995.

Located just south of Ortonville on Highways 7 & 75, the refuge offers a hard-surfaced 9.3 mile auto tour route. Hiking trails begin at the edge of the parking lot complete with public restrooms. A public canoe access is also available and wildlife observation opportunities abound.
