Forestville/Mystery Cave State Park: Minnesota's Longest Cave and Scenic Refuge

Tucked away in the southeastern corner of Minnesota near the town of Preston lies one of the Midwest's most fascinating natural wonders: Forestville/Mystery Cave State Park.

Far removed from the bustling cityscapes, this sprawling scenic refuge offers a unique blend of geological marvels, historic preservation, and exceptional outdoor recreation, making it a premier destination for nature lovers and history buffs alike.

Inside Minnesota's Longest Cave

The crown jewel of the park is undoubtedly Mystery Cave. Spanning over 13 miles of known underground passages, it holds the title of the longest cave in Minnesota.

Unlike many commercial caves that have been heavily modernized, Mystery Cave retains a rugged, authentic atmosphere. Visitors can take guided tours through the subterranean landscape, marveling at the intricate networks of stalactites, stalagmites, and underground pools. The temperature inside the cave remains a constant, cool 48 degrees Fahrenheit year-round, making it a perfect retreat during the sweltering summer months.

Historic Forestville

Above ground, the park offers a journey back in time. The restored 1800s village of Historic Forestville allows visitors to step into a meticulously preserved pioneer town.

Operated by the Minnesota Historical Society, the village features costumed guides who bring the past to life. You can explore the old general store, the Meighen family home, and agricultural buildings that highlight what life was like in rural Minnesota before the turn of the 20th century.

Camping, Fishing, and Trails

Beyond the caves and history, the park is a haven for traditional outdoor recreation.

• Trout Fishing: The Root River and its tributaries flow directly through the park, renowned as some of the best blue-ribbon trout streams in the entire state. Anglers frequently pull massive brown and brook trout from these clear, cold waters.
• Equestrian Trails: Uniquely, the park is highly popular with horseback riders, offering miles of dedicated equestrian trails and specialized campsites equipped with horse tie-outs.
• Camping: Whether you prefer pitching a tent under the stars, parking an RV, or renting a rustic camper cabin, the park provides excellent, well-maintained facilities.

For travelers seeking a multi-dimensional outdoor experience that combines deep geological exploration with rich local history, Forestville/Mystery Cave State Park is an unparalleled destination in the American Midwest.
