ONGAMIRA, 25km northeast of Capilla del Monte and 1400m above sea level, is a remote hamlet famed for its Grutas, strange caves amid rock formations sculpted by wind and rain in the reddish sandstone, and painted with black, yellow and white pigments by indigenous tribes some six hundred years ago. The drawings depict animals, human figures and abstract geometric patterns, and must be surveyed from a special viewpoint as the extremely fragile stone is gradually crumbling away and many of the paintings have already been lost.

The Parque Natural Ongamira is a privately owned reserve affording breathtaking views of the cerros Pajarillo, Áspero and Colchiquí; you can see condors, go on horseback rides and follow a 3km trail up to the top of Cerro Colchiquí.
