FRENCH CREEK STATE PARK CAMPGROUND, NEAR PHILADELPHIA, PENNSYLVANIA: GPS 40°11'54"N, 75°47'36"W
It's important to note that dogs are only allowed in one loop (I think it is the C loop).
The sites are close together, but some have space in the back. Ours did.
The bathrooms are adequate flush toilets. Not great, but they have free showers that are decent.
Surprisingly, it was very busy when we were there in late October.
