Great small campground in South-central PA.  Sites are nicely spaced except for a few that are tucked into a few odd-shaped places.  I stayed in site 21, which was on an outside loop with a lot of space.  Campground seems very well maintained and the hosts were very friendly and active.  I wasn't there on a busy night, but nice to know it is a place where the hosts are trying to keep a relaxing atmosphere.  Nearly everything is in the woods so there's lots of shade during the warm seasons.  There's a fire ring, picnic table, lantern hanger and generous tent pad.  There's also room in many outside loop sites to set up in the woods.  Very quiet and relaxing evening.

Bathrooms feel very modern and there is a combination of a traditional shower/bathroom center and a separate bathroom only area with 4 private bathrooms (though now showers).  Showers were clean and had hot water, though when you press the button for water, it only runs for about 10 seconds.  So you really have to just hold the water on while you shower one-handed.  I think there was a 1-car per site rule while I was there.

Firewood is on-site for $5 for a six-piece bundle, with kindling available.  Wood lit right up for me.  The park has a general store, swimming lake, Appalachian Trail Museum, Park office and a few other historic buildings so there's a lot to do.  Just take note that everything closes at 4 PM.  The park is just north of the halfway point of the AT and is a popular place for hikers to stop and take a slow or zero day.  The museum is interesting if you have any interest in the AT and very knowledgeable host.
