Was there a few months ago. I love this area. Cook Forest is about 10-11 miles from Clarion, PA where I attend college. The state park is one of the most popular in the state, I think. The Clarion River provides lots of water activities, etc. and there is lots of hikes to do including a walk to the Fire Tower right from the campground. But I’m not a fan of this campground. There are over 200 sites in the campground and it is frequently full. Sites are way too close to each other. The weekend I was there this last time, it was packed. The sites appear to be level and have all the amenities but I will not camp there again due to the size.
