This is the surviving technical building from Shenandoah’s Piney River Civilian Conservation Corps camp, just off Skyline Drive at milepost 22.1. It’s a modest stop for visitors curious about how the park took shape. The building is listed as open to the public, but it sits within a working maintenance and trail-crew area; visitor parking and the approach aren’t clearly documented. Piney River can also be reached on foot by the Appalachian Trail and Piney Branch Trail, though access to this building itself is less clear.
