In the agency’s own words

The Mill Run Camping Area is located on Youghiogheny River Lake in the heart of the Laurel Highlands. The lake spans the Mason-Dixon Line between Pennsylvania and Maryland. Clean waters, forested mountains and steep-sided valleys provide an unsurpassed setting for recreational opportunities. Keep reading

Recreation

Camping, fishing, boating, water skiing, hiking, biking, picnicking and sightseeing are the area's most popular activities. Boaters consider Youghiogheny River Lake, with its 16-mile length and channels up to one-half mile wide, the best powerboating and water skiing lake in southwestern Pennsylvania.

Facilities

The campground contains 30 sites that are all self-contained. Flush toilets, drinking water and a dump station are available. There is also a beach, boat launch and children's play area located in the campground.

Natural Features

The country surrounding the lake is made up of narrow valleys and high rounded hills with steep slopes. Much of the land is covered with northern hardwoods including beech, sugar maple, white ash, yellow poplar and basswood. A variety of wildlife makes its home around Youghiogheny River Lake, including deer, turkey, grouse, rabbit and squirrel.

Nearby Attractions

Some of Pennsylvania and Maryland's finest state parks surround Youghiogheny Lake. Ohiopyle State Park is known for some of the best whitewater in the East and is often the location of national kayaking competitions.

Who keeps the booking fee

The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.

OpenStreetMap has no toilet mapped within 1 km of this campground, so no site here carries a toilet distance. That’s a gap in the map, not a finding about the campground.

How we know

every fact on this page, and where it came from
Right now: U.S. Army Corps of Engineers publishes no season and no closure for this campground, and it takes no bookings we can read. That’s a gap in the record and not a locked gate: the number below is the only way to be sure.
Fall color: More Than Just Parks foliage tracker, joined to this campground by distance (32 km) · Oct 15, 2026
Reported by: Pennsylvania DCNR, reported peak color · Oct 15, 2026
Cell signal: the Army Corps’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
