We visited this park a few weeks ago with friends and had an amazing time! The park is set up on the land of an old factory that used the river to power a water wheel. There are a whole bunch of trails of varying difficulty and length that meander through the woods along the river. Along with the campgrounds there are also picnic benches and large group areas where you can host a lunch or dinner. We took the trail that shows you where they built the mill then goes along the river for a while. It was a beautiful hike but definitely challenging since there are a lot of rocks you have to climb over. The campgrounds are nice and across the road from the park through you can also take other trails from there that go down and around the reservoir. The amenities are nice and the whole park is well taken care of. I would highly suggest staying the night since it is such a short trek from the Atlanta area.
