Giant City State Park is AWESOME! Not much has changed since my first visit 35 yrs ago, and that is what makes it AMAZING. Its beautiful, hiking paths and everything else you would expect in a state park. But wait, there's more.
The Lodge at Giant City State Park has amazing food, go there on Sunday for the all you can eat fried chicken with all of the fixings. It is delicious!
If you wanted to get away for a few days or a week, they have cabins available for rent.
Giant city state park is a must see/must visit.
