Hot Springs in Big Bend National Park, also called Boquillas or Langford Hot Springs, was the first major tourist attraction in this part of the region and grew from a thermal spring into a resort along the Rio Grande. Beginning in 1909, J. O. Langford developed the site after seeking relief from chronic malaria, eventually working cooperatively with Cleofas Natividad’s family, who were already there. The resort added bathhouses, shelters, a store, and cabins before declining, but the mineral spring remains in use. The place also preserves evidence of a much older human presence, from Native American petroglyphs to early historic Indigenous farming and travel routes.
