Perrot State Park, where the Trempealeau River meets the Mississippi River, has 1,270 acres of diverse ecosystems. The river bank and surrounding wetlands provide wonderful habitat for the many migratory birds that travel through this area twice a year. Hardwood forests with mature black walnut, oak, and hickory are home to many animals, birds, and woodland wildflowers. Unique to southwestern Wisconsin and Perrot are the goat prairies perched high on the bluffs.
