Lower Walnut Bottom Campground (Site 37) is a backcountry campsite located at 3,000 feet elevation along Big Creek in Great Smoky Mountains National Park, accessible via a 5. 6-mile hike from Big Creek Ranger Station.

The site features five individual campsites with flat, root-free tent areas and excellent tree coverage, accommodating up to 20 people by reservation, with fire rings and food storage cables available.

Fishing is reported to be very good in Big Creek upstream from the campground, and the site serves as a base camp for accessing multiple feeder streams and connecting trails including Low Gap Trail to the Appalachian Trail.
