About
Tompkins Campground occupies a scenic position on the north shore of Cowanesque Lake in Pennsylvania's northern tier, less than a mile from the New York state border. Managed by the U.S. Army Corps of Engineers Baltimore District, the campground sits within the Endless Mountains region along the Allegheny Plateau, surrounded by rolling forested ridges and open fields. The campground features 125 total sites: 109 traditional campsites and 16 tent-only hike-in sites accessible by foot or boat. Most shoreline sites offer 50-amp electric and water hookups, with sites accommodating RVs and trailers up to 47-52 feet depending on the site. Standard nonelectric sites are also available. Facilities include hot showers, drinking water, a dump station, two overlooks, and playgrounds. Cowanesque Lake offers diverse recreation including swimming, boating with a boat ramp and overnight mooring, and fishing with two downstream tailrace access points. Fishing tournaments are held frequently. The 4-mile Moccasin Trail winds through reclaimed farm fields and woodlots, providing opportunities for wildlife watching. The surrounding forests support hunting for large and small game species native to eastern hardwood forests.
