Forestville/Mystery Cave State Park, State park with cave system in Fillmore County, Minnesota.
The park encompasses 3,170 acres of forests, wetlands, and restored prairies alongside a historic 19th-century settlement and underground limestone cave system point.
The area transformed from a rural trade center in the 1800s to a state park in 1941, preserving both natural formations and cultural heritage.
Minnesota Historical Society maintains Historic Forestville as a living museum where interpreters in period clothing demonstrate daily activities from 1899.
The cave system maintains a constant temperature of 48 degrees Fahrenheit, requiring visitors to bring appropriate clothing for guided underground tours.
Mystery Cave contains over 13 miles of mapped passageways through limestone bedrock, making it the longest cave system in Minnesota.

Minnesota contains numerous locations away from the main tourist circuits. The state stretches from the shores of Lake Superior to the southern prairies, encompassing historic lighthouses, underground mines, waterfalls, and Japanese gardens. Visitors find both natural landscapes and cultural sites that tell the story of the region's history. Notable locations include prehistoric rock carvings at Jeffers Petroglyphs Site, where indigenous peoples left their marks thousands of years ago, and sacred trees of Ojibwe culture. The geological formation known as Devil's Kettle, a waterfall whose course puzzled scientists for years, attracts visitors interested in natural phenomena. Historic mines provide insight into Minnesota's industrial past, while lighthouses recall the maritime history along the largest of the Great Lakes.
