Lenox Marcus is a free Army Corps of Engineers Class D campground on De Gray Lake offering basic amenities including flush toilets, picnic tables, grills, and a boat ramp for water access.

The 200-acre area provides first-come, first-served camping with both designated sites and remote pull-offs, though facilities are rustic and aging with limited cell service.

Note that bathrooms lack maintenance and doors on stalls, and the area can attract questionable activity, so visitors should exercise caution and lock valuables.
