Birch Campground at Greenbrier State Park offers 165 campsites in a wooded setting with clean bathhouses, hot showers, and a dump station, making it suitable for both tent and RV camping.

The campground provides direct access to a 42-acre man-made lake for fishing and paddling activities, with boat rentals (canoes, kayaks, paddleboards) available at the concession stand and a boat launch for electric trolling motor boats.

Note that the park experiences heavy crowding on summer weekends and holiday periods, so arriving early is recommended for parking and day-use lake access.
