Black Gap Road is located in Big Bend National Park and is the most well known jeep trail in all of Texas. The road is located in very remote, rugged terrain and is rated as difficult. The route features lots of challenges including off-camber sections, loose rock, loose sand, deep washouts, and a larger ledge obstacle called the Gap. The route is passable by most high clearance 4WD vehicles but wider vehicles may be prone to some pin stripping. Wet conditions can also cause flooding of the washouts so check with the NPS for weather updates before entering. A national park pass is required for entering the park.
