The Quebrada de Palala is a short, dramatic canyon just north of Tupiza, famous for the red-rock fins that locals call Los Cuernos del Diablo — the Devil's Horns. Bands of harder rock have weathered into vertical blades twenty metres tall, separated by sandy washes.
Most riders pass through Palala on a half-day horseback trip from town. The morning light is good for photographs, and the road through the canyon is easy enough to walk if you would rather skip the horse.
