Big Flat Campground is a small, quiet 8-site campground in Six Rivers National Forest bordered by Hurdygurdy Creek, offering vault toilets, picnic tables, and fire rings, though water is not available.

While there is no direct river access from the campground, several South Fork Smith River access points are located within a half mile, and Hurdygurdy Creek can be accessed directly from the site.

The campground operates on a first-come, first-served basis from late May through late October and accommodates trailers and RVs up to 32 feet, with sites ranging from 37 to 120 feet in length.
