We did not stay here, but were staying at Robert H Treman SP. We took a day trip to see this water fall and did a side trip just to check this CG out. Sites are generally pretty small. Park Advisor states maximum 30'. I would say there are only a few that can handle that size. Class B, small Class C, or a very small trailer for most sites. Many of the sites are set up angled backwards from the direction of travel down the one-way loop road. They would be impossible to back into, unless you drive the wrong way down the road. It appeared many had. The waterfall is not to be missed, though.
