Mercer / Grove City KOA Holiday at 1337 Butler Pike, Mercer, Pennsylvania.

I had a very positive experience at this campground. The shower house was clean. The staff was helpful and friendly. I was there for only one night at the last minute during my road trip. I had a tent site with electric. The sites were clean. The staff gives a small garbage bag at check-in and does a garbage pick-up each day. Very kid-friendly: tractor hay rides, swimming pool, and various activities. If my kids were younger this would be a great place; it reminded me of my own childhood camping experiences. I will return.
