Visitors can once again experience natural wonders above and below ground at Forestville/Mystery Cave State Park located in southeastern Minnesota. Cave tours are now being given following the state shutdown.

Discovered in 1937, Mystery Cave is the longest cave in Minnesota – spanning more than 13 miles underground. It is a network of passages that was created when rock was dissolved by moving water. Park naturalists guide tours through various portions of the cave and explain its history, its features and how it was formed. One-hour cave tours are designed to be fun and informative for all ages. They are ADA accessible.

Another perk to cave tours during this hot Minnesota summer is the temperature. The cave stays at a constant 48 degrees year-round.

One-hour cave tours are offered every day through Labor Day between 10 a.m. and 5 p.m. Two-hour and wild caving tours are offered on weekends. Details can be found on the park website at or by calling 507-937-3251.

Forestville/Mystery Cave State Park has also opened its main campground, horse campground and trails. Historic Forestville, a restored 1800s village operated by the Minnesota Historical Society, reopened July 23.

Forestville/Mystery Cave State Park is located between Spring Valley and Preston, six miles off of State Highway 16. Signage will direct visitors to the park or cave.
