Texas has 12 hot springs, including 0 free primitive soaks and 12 paid resorts, most notably the free Boquillas (Langford) Hot Springs on the Rio Grande inside Big Bend National Park, where soakers sit in a 105°F historic stone tub with the river running past their toes and Mexico on the far bank. Texas is the only state where you can soak in a natural hot spring while looking across an international border into another country. Springs cluster in two regions: the Big Bend / Rio Grande borderland (Boquillas/Langford, Chinati) and the Trans-Pecos desert (Balmorhea's cold artesian pool is not hot but is a nearby draw). Flagship sites: Langford (Boquillas) Hot Springs and Chinati Hot Springs. Texas's thermal activity is driven by deep circulation along Basin & Range extensional faults in the Trans-Pecos. Surface temperatures at Langford are ~105°F. Land ownership is National Park Service (Big Bend) for Langford and private for Chinati. Access to Langford is a short walk (roughly 0.5 mi from the parking area) while Chinati requires a long high-clearance drive west of Presidio. Best season is October through April and summer Big Bend heat is dangerous. Gateway airports are El Paso and Midland/Odessa (both are long drives, 4-5 hours to Big Bend). Swimwear is required at Langford (NPS) while Chinati allows more privacy. Reviewed and updated July 2026. Use the map to combine with Big Bend backcountry planning.
