Become one with the Forest...
The Clarion River and the Forest Cathedral are the stars of the show here at Cook Forest, and the Friends of Cook Forest take full advantage of the natural wonders of our park! In fact, our number one priority is an all out assault on the Hemlock woolly adelgid that threaten the beautiful hemlocks of the Forest.
The Friends Group joined in a community search for locations of Hemlock woolly adelgid in Cook Forest. We found them, and it became an important part of The Cathedral documentary being filmed at the time. The films production and viewing around the state helped earn Cook Forest State Park the '2018 Pennsylvania State Park of the Year' Award.
