Thayer Campground is a primitive, tent-only campground with 4 walk-in sites located directly on the New River in Fayette County, offering free camping on a first-come, first-served basis with no reservations.

The campground provides direct river access for fishing and paddling but has no amenities—campers must bring all water and supplies, and alcohol is prohibited.

Access requires traveling an unpaved road and crossing railroad tracks, making it suitable only for experienced campers seeking a remote, self-sufficient riverside experience.
