We were bike touring in the area and needed a place to camp. We ended up staying in a pretty meadow on Walters property down a rough road, but it definitely did not feel worth $25. My expectation was that there'd be something - a mowed field, a platform, or a view. But it was just an overgrown meadow about a mile down a class IV road.
It did not help that there was no map at the front entrance, as described. Nor was it even clear what the front entrance was. So we had to bike up and down the road for a while until Walter called us back to let us know where we could go.
In short, camping experience itself was fine, since we were prepared to primitive camp, but
it was very confusing to find and did not feel worth paying for.
