Located 8 Miles off of I-81. parked my pickup truck with camper shell in the tent campsite number 35. Plenty of mosquitoes so bring a citronelle candle and bug spray. Other than that it's a quiet campground during the week with clean facilities. The after hours honor system put a check in an envelope registration, including the $4.50 senior discount, the weekday (Sunday Thru Thursday) out-of-state resident fee was $27.
Not south of Pittsburgh.
The little creek campground in the Eugene T. Mahoney State Park is nicely kept and has showers. It is mostly quiet but you can hear the background drone of the Interstate highway. The park has a vehicle pass fee ($8) and a camping fee. I am tent camping and the least expensive site was $25.
Day use area. Gates close at sunset.
