Mountain
Los Seismiles
West of Fiambalá, the paved road winds through the high desert, past picturesque red rock escarpments known as the Quebrada Angosturas, and into some serious altitude, topping out at the Chilean border. It's a stunning drive, with no services apart from a seasonal white-elephant hotel halfway between Fiambalá and the frontier. Los Seismiles are the peaks above 6000m, and you'll see several of them, including Ojos del Salado (6879m), the world's highest volcano.
