The Organized Group Tenting Area at Pymatuning State Park is not open to the public, but is available to registered non-profit groups. There are 9 group sites that hold between 20 and 100 people, and the Group Campground is rustic, with pit toilets, but no showers. The park itself has its own playground and ballfield for serious games of capture the flag, or you can spend the day on the water, soaking up the rays, playing mermaid, and fishing for walleye, carp, and bass.
The nearby Jamestown Campground has laundry facilities, a camp store, and hot showers, and is open to the public.
