Beautiful scenic place to stop along the lake. Lots of places to sit and enjoy the view, picnic and clean well lit walk trails.

The park is beautifully maintained and has a lot of very mature, huge trees. The grass looks like a golf course. Our campsite (85) had a nice view of the water, was next to a playground and was a very short walk to the pool. The pool area was nice and the splash pad is an added touch. We loved our experience and will definitely return ❤️

It's a very busy campground but as busy as it was it was extremely quiet. Sites are pretty level and park is very clean. Check out on Sunday is a bit early with it being the busiest check out day everyone trying to use the dump stations. Wish Ohio would extend Sundays check out later by 2 hours like other states so people could stagger out a little more and not clog up traffic
