Forestville Mystery Cave State Park, 21071 Co Hwy 118, Preston, MN 55965
Forestville has it all camping, hiking, horseback riding (bring your own, I think), and even a cave.
The park is in two sections. One section has the main part of the park where you will find the majority of the trails, the fishing area, the old Meighen Store, and fishing. This is a great place to catch a trout apparently.
The Meighen store is across the bridge that is out, pedestrians only these days. Plenty of people try their had at fishing along the stream that runs under that bridge. Take a look around.
There is a pretty good trail just across the bridge. It will get your heart racing if you take it very far, but the view from the lookout is nice. Most of the trails seem to be both hiking and horses so watch your step.
You can rent a cabin and stay in the park. Take a few days and enjoy as much of the park as you can. It is a rather large park. We explored a good portion of two days.
When you have your fill of the main area of the park you can head over to the gem of the park Mystery Cave. Yes, the cave has bats, but they are cute little bats that eat the mosquitoes in the area which is great.
I highly suggest checking out Mystery Cave. Take a tour. Reserve your spot. Enjoy the dark and most importantly the trip through time.
