Southeast of El Paso and east of Presidio in the Big Bend region, the Contrabando Loop is a 23 mile route of singletrack and doubletrack. Located within the Big Bend Ranch State Park, the loop is best ridden counter-clockwise. There are three main trailheads servicing the region: the East Trailhead, the West Trailhead and the Sauceda Ranger Station trailhead.
The 300,000 acre Big Bend Ranch State Park has over 200 miles of doubletrack and singletrack. These route roll through some of the most remote and rugged desert terrain in the Southwest. Overall, the state park encompasses two mountain ranges containing ancient extinct volcanoes, precipitous canyons, and waterfalls.
There are several camping areas within the state park. These primative campgrounds are located at Madera (Monilla) Canyon and at Grassy Banks River Access along FM170. The two group camping areas, Contrabando and Arenosa, have self-composting toilets. The 10 small, designated primitive campgrounds along the gravel park road in the backcountry are accessible to high-clearance vehicles only.
