This was our first trip to Jellystone in Quarryville, and I don't think it will be our last! This is a perfect campground if you have kids. The amount of daily activities is great! We participated in many of them. The water park/pool area was great as well--we went there every day for several hours. The location is perfect--we were able to enjoy a local winery as well as a Lancaster Barnstormers game. The park is clean and well-maintained, and most of the staff were friendly and helpful. I'm sure we will come back next year! One thing I think could be improved is a cover over the playground, which is in full sun most of the day--too hot for the kids to play on.
