Cute little campground, very quiet and relaxing. We have a 42' fifth wheel, not a whole lot of sites to accommodate, but we had a nice one by the stream. The sites are all grassy, and it rained quite a bit while we were there, so it got a little muddy. There were a few activities, but we opted to check out some local shops and restaurants instead. Amish kids selling cookies and donuts going from site to site.
We were on a 30 amp site, and our camper is 50 amp, so make sure you have a converter if this is you. We blew a fuse around 9 am, no one in the store and no one answered the phone, and the breakers aren't at each individual site, so we had to drive around and find the breaker box ourselves. No sewer sites, but there's a dump on site.
A few odd rules (no riding bikes across the street) and the store is tiny. Whoever was working when we checked in wasn't overly friendly, which seems consistent with some other Google reviews.
We live fairly locally (45 minutes) so come to the area often, not sure if we'd come back or not. But all in all, we enjoyed our quiet and somewhat rainy weekend at Red Run.
