33. Big Stone National Wildlife Refuge

Approximately 1 mile southeast of Ortonville, off of TH 7/75. The Big Stone National Wildlife Refuge consists of 10,795 acres of marsh and open water created by the three-mile dam across the Minnesota River Valley. More than 230 bird species have been observed in the area since 1971. The refuge offers a four-mile self-guided auto tour. You will see western prairie grasslands, flooded forest, mixed habitat and wetlands. A foot trail provides a close-up view of prairie plants, river meanders and wildlife. The 100 acres of granite rock outcrops support unusual species of cactus and other plants and provide an excellent view of the refuge. Pick up the tour leaflet at the first tour stop.
