Improved Dirt Roads
Dagger Flat Auto Trail
This seven-mile road (14 miles round-trip) winds eastward to a small valley with a forest of giant dagger yuccas. A self-guiding brochure is available and provides a key to the desert plants. Typically open to most vehicles, this road is also good for mountain biking. Speed limit on this narrow road is 25 mph: allow two hours round-trip. Sandy areas or muddy conditions may exist seasonally; rain makes this road difficult to drive or impassable. Please inquire about current road conditions.
Grapevine Hills Road
Travel 6.4 miles down this road to access the Grapevine Hills trailhead. Here, the 2.2 mile round-trip Grapevine Hills Trail leads to the picturesque Balanced Rock. Geologically, Grapevine Hill is a laccolith—a mushroom-shaped igneous intrusion that domed the rocks above, and was later exposed by erosion. The road is generally accessible to all vehicles, and begins 3.3 miles west of Panther Junction on the north side of the road. Beyond the trailhead, the road requires high-clearance, especially after any rainfall.
Hot Springs Road
Note: Motor homes and oversize vehicles are prohibited on the one-way sections of the Hot Springs road.
Old Maverick Road
The Old Maverick Road runs between Maverick Junction and Santa Elena Canyon. It is a 14-mile improved dirt road that passes along the Terlingua Creek badlands on the west side of the park. A number of historic sites are located near the road that you may visit as you gradually descend to the Rio Grande and Santa Elena. While usually passable for most vehicles, this road tends to be rough and washboarded; the fourteen miles takes around an hour to drive. This road is subject to high water and flooding following rainstorms.
