Buffalo River State Park
🌾 Minnesota’s Last Tallgrass Prairie — A Vanishing Ecosystem with Swimming, Camping, and the Bluestem Prairie Nature Conservancy Preserve — Buffalo River State Park near Glyndon, Minnesota with tallgrass prairie (one of MN’s last intact stands), adjacent Bluestem Prairie TNC Preserve, Buffalo River swimming, camping, hiking, cross-country skiing, wildflower viewing (prairie smoke, blazing star, goldenrod), prairie birds (bobolink, dickcissel, meadowlark), Red River Valley — Clay County, MN
Less than 1% of Minnesota’s original tallgrass prairie survives. Buffalo River State Park protects one of the finest remaining stands — a sea of big bluestem, Indian grass, and prairie wildflowers stretching to the horizon, adjacent to the Nature Conservancy’s Bluestem Prairie, one of the largest protected prairies in the upper Midwest.
The park also wraps around the Buffalo River — clear, shallow water with a designated swimming area and a wooded campground in the cottonwood floodplain.

The Tallgrass Prairie Ecosystem
Before European settlement, tallgrass prairie covered 18 million acres of Minnesota. Today, less than 1% remains — making intact tallgrass prairie rarer than tropical rainforest. Buffalo River State Park and the adjacent Bluestem Prairie protect one of the most significant surviving stands.
