Marfa on FM 2810 (also called Pinto Canyon Road), you first see grasslands, then these rolling hills, then rocky treacherous terrain (fit best for high clearance, all-wheel drive vehicles), and every mile is a delight or adventure or both! The road takes you to Ruidosa, a tiny hamlet along the Rio Grande.
Part of the road is smooth and paved, but after a few miles it becomes quite rough. While it is tempting to want to get out and explore the rugged stretches by foot, keep in mind that the road cuts through private land and access off the road is not allowed. Still, the amazing scenery makes the drive MORE than worthwhile!
