Introducing La Quiaca
After leaving the Quebrada de Humahuaca, paved RN 9 passes through Abra Pampa, a forlorn windy town 90km north of Humahuaca, and climbs through picturesque and typical altiplano landscapes. Look for the endangered vicuña off main routes.
La Quiaca is divided by its defunct train tracks; most services are west of them. North of town, a bridge across the river crosses to Villazón, Bolivia.
