The incredible rock art of Cueva de las Manos was proclaimed a Unesco World Heritage site in 1999. Dating from about 7370 BC, these polychrome rock paintings cover recesses in the near-vertical walls with imprints of human hands, drawings of guanacos and, from a later period, abstract designs. Of around 800 images, more than 90% are of left hands; one has six fingers.
Plans are in the works to open hiking trails leading from the visitor center. Consult with rangers upon arrival.
