Flat Rock Extension Campground

Just upriver from Flat Rock Campground, this little campground is a favorite. Shaded sites sit along the road and the Yankee Fork River is across the road. Three campsite facilities include picnic tables, tent pads and fire rings with cooking grills. The campground has a vault toilet and accommodates trailers and motorhomes up to 16 feet. There are no hookups, drinking water is only available from nearby Flat Rock Campground.
