Visit Forestville/Mystery Cave State Park to see natural wonders above and below ground. In the summer, beat the heat with a visit below ground. Explore the world of Mystery Cave with its stalactites, stalagmites, and underground pools. Park naturalists provide tours of the cave throughout the summer and on weekends in the spring and fall. The temperature stays at a constant 48 degrees Fahrenheit. Learn more about Mystery Cave Tours. Above ground, stop by Historic Forestville, a restored 1800s village operated by the Minnesota Historical Society (MHS). Fish three blue-ribbon trout streams for brown trout. Take in the soft pastels of wildflowers in spring or listen to ruffed grouse drumming and wild turkeys gobbling. Hike or bring your horse to ride the ridge tops and stream valleys. Observe interesting geologic features along the way including sinkholes and dramatic Big Spring. In the fall, don't miss the bold colors of the forest. Winter invites visitors to ski or snowmobile the Bluff Country.

This is a great trail. Trail to the Big Spring is fairly flat and has bridges over the river. Very scenic walk with limestone bluffs on both side of the trail and springs coming out of the bluffs. Good trout fishing too.
