Lightly traveled roads and varied terrain make Big Bend a premier bicycling location, the NPS says. There are more than 100 miles of paved roads, and 160 miles of backcountry dirt roads for riders of all types and skills. Adventure Cycling offers a 9-day, van-supported trip explores the wild and picturesque terrain of the West Texas Big Bend region. Velo View Bike Tours has several quite challenging trips as well. You will bike between 30 and 60 miles a day and go more than 4,000 feet in elevation.
