Had a great weekend camping at Col Denning 14-15 June 2013. This is a rustic (non-flush / no showers) campground. Beautiful location with a great hike trail out to Flatrock vista. The hike is moderate 2.5 miles and took us 3.5 hours round trip. Campground is very friendly and has an active friends of Col Denning Campground that was having their work weekend when we were there. Campground hosts are very nice and accommodating, Easy to get to off I-81 from the Newville Exit on Route 233. We will come here again.
