This is a nice little park that used to have a lake…until it was undermined (literally) and destroyed by the nearby coal company. The trails are pleasant, especially the one leading to the old Chess Cemetery. The PADCNR works hard to make this park into an attraction despite the fact that it no longer has its lake as a focal point. This means that they maintain a cold water swimming pool in the summer. And they keep the campground open year-round, which makes it a rarity. If you want to go camping in January, this might be the only conventional campground in PA where you can do that. The campground is pleasant, if a little…spooky. None of the spots are very secluded, but that's okay because you'll probably be the only camper here. Like much of the park, it's bordered by a public road, which means that there's some traffic--usually loud pickups and frack trucks. I've only ever camped here in the fall, when Greene County is at its most beautiful, and I've always had the campground (and most of the park) entirely to myself. There are two tiny cabins as well as sites for tents or campers. Ryerson is worth a visit. Not sure why the state can't make the coal company pay for its destruction of the lake.
