Nice campground with a family friendly environment. Sites are well shaded, restrooms and showers are very clean. Only real draw back is there is no pool at the campground, instead you have to pay admission to Dutch Wonderland to use the water park to cool down.
My family and I just got back into camping this year and have made several trips to Jellystone as it is local to us. The campground is a very family friendly environment and the owners go out of their way to make you feel welcome. There are many fun and structured activities for kids and families of all ages plan through out the weekend. The campground has make some major improvements since our first trip (first week of May) to the road leading into the park, the swimming pool, and the electrical hook-ups.
