We stayed at this State park on 12/27/2020.  We were not able to visit the caverns as all tickets had been sold when we arrived in the morning!  Plan ahead and purchase tickets in advance online.  The RV park was fantastic.  Our site was W/E with a dump on exit.  The site was level with a asphalt pad, some shade, a fire ring and picnic table was provided.  The bathrooms and showers were super clean as well.  There are hikes on the property that were well maintained as well.
