Although it attracts far fewer visitors than neighboring Parque Nacional Lauca, Reserva Nacional Las Vicuñas contains some incredible sights—salt flats, high plains, and alpine lakes. And you can enjoy the vistas without running into buses full of tourists. The reserve, which stretches some 100 km (62 mi), has a huge herd of graceful vicuñas. Although quite similar to their larger cousins, llamas and alpacas, vicuñas have not been domesticated. Their incredibly soft
wool, among the most prized in the world, led to so much hunting that these creatures were threatened with extinction. Today it is illegal to kill a vicuña. Getting to this reserve, unfortunately, is quite a challenge. There is no public transportation, and the roads are passable only in four-wheel-drive vehicles. Many people choose to take a tour out of Arica.
