RV travel guide
Hudspeth County
County seat Sierra Blanca, 4,571 sq mi across Texas. Everything an RV traveler should read before rolling in — where you can boondock, the roads worth the detour, and the local rule that actually matters.
The county in brief
A traveler's read on Hudspeth County
Hudspeth County is the only Texas county with a Mountain Time Zone observation — the rest of Texas runs Central — making it the only spot in the state where the wall-clock matches Albuquerque, Salt Lake City, and Denver. Sierra Blanca (population 553) is the county seat and the location of the eastbound I-10 Customs and Border Protection checkpoint that every vehicle must clear.
The county wraps 90 miles of US-Mexico border along the Rio Grande, the western Guadalupe Mountains foothills, and the Quitman Mountains rising to 6,500 ft. Indian Hot Springs at the southern county boundary along the Rio Grande is a privately-operated rustic resort accessible only by 30 miles of unpaved FM road from Sierra Blanca, rig-capped at 25 ft by the resort's own access-road geometry.

Seeing Hudspeth County from a rig
