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

The site features both open lake and cove-side tent and RV camping (no hookups), with concrete pads and grills available, though facilities are minimally maintained and restrooms may have wasps.

First-come, first-served with up to 14 days free camping; arrive early as sites fill quickly, and note that some remote dirt road sites may be difficult to access in wet conditions.
