South Ruby Campground sits at 6,000 feet elevation in the Humboldt-Toiyabe National Forest near Ruby Lake and the Ruby Lake National Wildlife Refuge, offering 35 campsites (33 single, 1 double, 1 accessible) with vault toilets, drinking water, picnic tables, and fire rings during the main season (early May to late September).

The campground provides excellent access to Ruby Lake for fishing and boating, with a fish cleaning station and trolling motor charging station on-site, plus nearby hiking via the Ruby Crest National Recreation Trail and opportunities for wildlife viewing of over 220 bird species.

The lower loop remains open year-round on a first-come, first-served basis with limited amenities, and the maintained dirt road access is suitable for standard vehicles, though RVs up to 50 feet are accommodated.
