This was our first Jellystone park and we loved it! The kids had a blast! So much water play fun as well as other activities. The site we stayed in was well shaded. I do agree with some of the other reviews that young kids were running the upper water slides and seemed less than enthusiastic to be there. Grumpy sort of look, too cool to be running a water slide which actually requires a significant amount of responsibility to ensure water safety. Otherwise, my kids still had a blast. While the train was brand new with leather seats! The golf course, my husband joked that if you ever wanted to play on an abandoned and overgrown golf course, this was the one to go to lol. Our site was conveniently right by the outdoor movie theater and my 4 and 6 year felt so independent that they got to go there by themselves. Yes the golf carts were ridiculous running constantly and all hours until 11pm...but if you are in shape walking up the hill to the upper water park wasn't as bad as everyone makes it out to be. You don't NEED a golf cart as others say you do. I pushed a double stroller with kids in it and our bags up the hill. We also went to Falling Water which was a short drive away and has been a goal of mine to visit for decades.
Beware there is no great way to access the park without driving up some steep roads. We were pulling a small travel trailer with our SUV for the first time and this was difficult on our car. When we return it will be with a more powerful vehicle to pull our travel trailer up! Overall great stay. Felt like a throwback to how childhood should be, away from all the technology and just pure family time and fun.
