Snag your spot on the bison bus at Blue Mounds State Park for a chance to view our mighty national mammal roaming the prairie of southwest Minnesota. Or, enjoy a cool (48° to be exact) afternoon in Minnesota’s longest cave in the state, Mystery Cave. Heading north? Join our interpreters as they guide you through the various Soudan Mine surface facilities. Learn about the miners and their jobs, see what happened to the ore once it reached the surface and explore the different equipment that was used in the process. See you soon!
