This park has now, after our first visit, moved to the top of the list among our favorite Pennsylvania State Parks. The layout of the campground is well thought out, with nice separation between sites, level gravel spurs, although some are fairly short, and decent shade on most sites throughout the day. The shower houses and restrooms appear to be recent construction and are clean, roomy and well lit. The 224 sites are spread through two campgrounds, with the Aughwick CG being the much larger. Quite a few electric sites are available along with a few pull-thru and some walk-in tent sites. We camped on site 117 and had more than enough room for our mid-sized tent camper, awning and 10x10 screen room, with the tow vehicle parked on the slope leading down to the road. Many sites on the inside of the loops have an incline leading up to the level pad while many outside sites have a steep drop-off behind the pad due to the hilly terrain of the campground loops. Pay attention to the site characteristics listed on the park's web site to make sure your camper will fit easily on the level pad. The park has a 40-some acre lake with two boat launches, a mooring area for campers, and a nice sandy beach. The lake was crystal clear -- we could see the bottom while swimming in six feet of water. There are a lot of well-marked trails through the park, a visitor center and a shower house/concession building at the beach. Buchanon's Birthplace State Park, a very small state park marking the place where President James Buchanon was born, is nearby and worth a visit. The scenery in the area, on the eastern edge of Pennsylvania's Allegheny Mountain region, is spectacular. We're already planning our next visit to Cowans Gap! We camped here in a Tent Trailer.
