Forestville State Park features the historic 1800s village of Forestville, preserved to depict life in a frontier town. The site is managed by the Minnesota Historical Society in partnership with the Department of Natural Resources. Beneath the surface, the park encompasses Mystery Cave, the longest cave system in Minnesota. The cave features underground lakes, stalactites, and stalagmites formed within limestone layers. Visitors can tour the restored 1856 Meighen Store and surrounding period-accurate buildings. The park is situated within the karst topography of the Root River Valley. Interpretive tours explain the geology of the cave and the social history of the village residents. The park office serves as the central hub for visitor check-ins and tour coordination.
