Forestville/Mystery Cave State Park

Forestville/Mystery Cave State Park is a protected area with forests, wetlands, and restored grasslands in Fillmore County, Minnesota. The site also features a historic settlement from the 19th century and an underground limestone cave system.

The area developed as a rural trade center in the 1800s and became a state park in 1941. This transformation preserved both the natural limestone formations and the historic settlement for future generations.

Historic Forestville operates as a living museum where staff dressed in period clothing demonstrate how people lived and worked during 1899. The settlement shows daily routines and tasks that were part of rural life in that era.

The cave system maintains a constant cool temperature year-round, so visitors should bring warmer clothing for the guided underground tours. The park has marked trails and parking areas that provide easy access to the main attractions.

Mystery Cave is the longest cave system in Minnesota with over 13 miles of mapped passages, drawing cave explorers and curious visitors to its underground passages. The limestone formations display millions of years of earth history in their layers and rock structures.
