High-Clearance Vehicles Only!
The River Road traverses the remote southern portion of the park, roughly connecting the areas near Castolon and Rio Grande Village. While generally following the course of the Rio Grande, the road runs a considerable distance from the river, especially in its mid-section near Mariscal Mountain. You cannot actually see the river along the River Road unless you take a side trip to one of the primitive roadside campsites located next to the river. Due to its length and usually rough road conditions, allow a full day to drive from end to end.

Before heading out on this road, be well prepared for safe backcountry driving with plenty of water, a jack, and good spare tire. The River Road crosses numerous washes, and regularly becomes impassable after rains. On these isolated, infrequently patrolled backcountry roads, a disabled vehicle can quickly become a life-threatening situation.

Highlights along the River Road include remote desert scenery, exploring historic sites, and experiencing some of the most remote areas in the United States. A variety of Primitive roadside campsites (permit required) located along the River Road, allow for extended exploration. The west side of the River Road is lesser used, and generally in a rougher condition than the eastern side.  

Protect Big Bend. Always stay on established roadways.
OFF ROAD DRIVING IS PROHIBITED.
