I have only been here a couple of times in the Summer, but this is a state park that does it right. They have a full lodge, and also offer a variety of very nice cabins that you can Sleep in.
They have sledding were you throw yourself down a massive hill, cross country skiing, horse trails , hiking and much much more. it was one of my favorite places to go when I was younger and one of my favorite places to take the younger cousins when I visit. There aren't it seems many places like this left in Ohio. or really anywhere that are free, old fashioned family fun.
Its worth checking it out.
