We have never been at an RV park where the sites were on grass but it worked. Our spot was fairly level and the grass added to the beauty of the location. The park is quiet and peaceful. Great bathroom and showers. Host was very friendly. This park is located just a short ways from the historical Fort Bridger site so very convenient. The only downside was the dirt road leading to the park and in the park. Some potholes and it had rained so there was considerable mud. We had to run our truck thru the local carwash. All and all I would stay there again.
