A 4X4 trail in the Big Bend National Park, rarely maintained by the NPS Start at Glen Springs, and end on the River Road
We drove this trail in March 2012 from east (Glen Springs) to the west in a stock Jeep Wrangler JK. The Park service seems to discourage using the Black Gap 4X4 road as they no longer maintain it. It is washed out in several places, but nothing a capable 4X4 can't handle.
I would check with the NPS before driving it, especially after a big rain.
