Oh well, it really sounded nice but, if it sounds to good to be true.......read more

Not as cramped together as other RV parks. Water, 30A/50A hookups and an on-site dump station. Clean bathroom and... shower room on-site no extra cost.read more

Friendly camp hosts and a clean campsite. We were close to the road and the traffic was busy. Not too bad though. This... was our first visit and now we known to go to the sites away from the road.read more

We enjoyed our camping/RV stay for three nights. The host and property managers work hard to keep a very old property... in good order. The bathrooms were well kept. It's an older campground that could use some updating from the owners, but overall a good spot with lots of shade.read more

We camped in a motorhome and tent. Good grass area for kids to play on. Nice fire pits and good bathrooms with a shower.
