Old Ore Road is a 26-mile primitive 4WD route through Big Bend National Park's eastern half, running north to south between the Dagger Flat Auto Trail and the Rio Grande Village area. Built in the early 1900s as a wagon road for hauling fluorspar, lead, and zinc ore from Mexican mines to the Marathon railroad station, the road follows its original alignment through the Sierra del Carmen foothills with little improvement.

The northern half is significantly rougher than the southern; both halves require high-clearance 4WD with sturdy tires. Eleven primitive roadside campsites along the route are available with backcountry permits ($10/night) from the Panther Junction Visitor Center. The road closes after heavy rainfall and is best driven October through April.

Field notes

Getting Oriented

Old Ore Road runs through the eastern half of Big Bend National Park in Brewster County, between Persimmon Gap (the park's northern entrance) and Rio Grande Village (the southeastern visitor area). Marathon, Texas on US-385 is the closest service town to the northern access, 40 miles north of Persimmon Gap. The road sits within the park's backcountry — primitive, federally managed, and sees light traffic.

Trail Overview

The northern access leaves Dagger Flat Road; the southern access connects to Rio Grande Village Road. From the north, the road descends into the Tornillo Creek drainage, climbs over the Dead Horse Mountains, and descends to the Rio Grande Village area. The northern half passes Ernst Tinaja (a year-round natural water tank), McKinney Spring, and Roy's Peak — the rougher and more scenic stretch. The southern half runs along the base of the Sierra del Carmen with views into Mexico.

Driving the full 26 miles takes 3 to 4 hours without stops. Most travelers spend a night at one of the primitive campsites and split the trip into two days.

Points of Interest

  • Ernst Tinaja. A natural water tank in eroded limestone, the most-photographed feature on the road.
  • Roy's Peak. A primitive campsite at the road's high point with panoramic views.
  • McKinney Spring. A reliable water source historically used by ranchers and miners.
  • Telephone Canyon. Scenic primitive campsites on the eastern side.
  • Dead Horse Mountains. The range the road crosses; sharp limestone ridges and Chihuahuan Desert vegetation.
  • Sierra del Carmen. Visible across the Rio Grande in Mexico, rising 7,500 feet.

Where to Camp
