Taos to Marathon Road Trip: High Desert to Big Bend

Few road trips capture the shift from high-desert alpine to rugged Chihuahuan scrub as dramatically as the 600-mile drive from Taos, New Mexico to Marathon, Texas. The route follows US-285 and US-90 through alpine valleys, high plains, and limestone canyons, crossing the Continental Divide twice. One curious fact: the highway passes within 10 miles of the Trinity Site, where the first atomic bomb was tested, near Oscuro, NM.
