I’ve been told this KOA is so good it would be unfair to judge other KOAs against it. The staff is friendly, welcoming, and accommodating. The amenities are all well kept and lovely. The pool is clean and comfortable. The store had everything we needed. Our cabin is a gem. I couldn’t be happier. It is better far better than the description or the pictures made it seem.

The amenities are all well kept and lovely. The pool is clean and comfortable. The store had everything we needed. Our cabin is a gem. I couldn’t be happier. It is better far better than the description or the pictures made it seem. Our 8 year old daughter is so happy with her bed, and so enamored with the adorable pigs in the art in our cabin. We had a nice easy trip to Hershey this evening and now we’re sitting here in the peaceful night air, roasting marshmallows by the fire. If other KOAs are 75 percent as wonderful as this, I’ll be thrilled that we’ve become members.

I can not say enough about this campsite. We stayed for 5 days. Our campsite was beautiful. We had 2 dogs with us and we used the dog pen that was at our site. The place was so clean and my grandkids had such a great time playing with everything they had. I would reccomend this campsite for anyone who wants to have a terrific time. I wish I could give it more stars. Beautiful and clean!!!!

An absolutely fantastic KOA. Everything about this place is fantastic. My greeting by Sabrina in the office made me feel right at home. The assistance finding and parking at my site was very much appreciated. The grounds are super clean and manicured. My site had a patio, rocking chairs, fire pit, gas grill and a round picnic table. Everything was clean and orderly.

Stayed in cabin 122. This was the ideal place to set up for a week. The internet worked great which was important since I work remote. The campground is incredible clean and there’s lots to do. The staff was great from check in to departure. If you’re looking for a campground in and around the Hershey area…this is the one! Also, check out Whisk.

We typically try to stay away from traditional campgrounds and normally boondock or Harvest host. We were a bit nervous booking a site, but, wanted to be close to the Hershey RV show. We can’t express how happy we were with both the facility and the staff. The sites range from your normal campground sites to sites with private patios, gazebos and even private dog parks.
