We tent camped here in early June.  GPS had a hard time as there are so many locations referred to as "Pymatuning State Park."  Campsite was fine other than trying to find room to put our big tent.  The showers were great--roomy and well maintained.  Wish there were more hiking trails; unless you fish or boat, there isn't a lot to do.  The Ohio State Parks website is a bit clunky!  Very little, if any cell service.
