As a campground owner I have been warned time and time again not to stay in a state park for plenty of reasons. But I must say this has been one of the best stays on our two week trip. I wanted to just try a state park and I was not disappointed. We only stayed one night as we were just passing through, but we will definitely be back. Dated but super clean bathrooms with the best water pressure and heat so far on our trip.
Small State Park, but it has a nice trail around the lake and a little wooded island with paths that are nice. There are also trails up through the woods behind the lake, but I haven't been on those.
