35 campgrounds with first-come sites in Texas

The list is thickest in National Forests and Grasslands in Texas. The Forest Service and the National Park Service run nearly all of them. Ratcliff Lake Recreation Area is the largest at 65 sites.

A campground is listed when Recreation.gov or the Forest Service records it as first-come, first-served. Campgrounds where some sites book online and the rest are first-come are listed too, marked partly reservable.
