This wide, shallow cave , whose name means ‘house of the sun’ in Quechua, makes an interesting stop, as much for the gorgeous surrounding countryside as the cave itself. Radiocarbon dating suggests that the cave was first inhabited by the Ayampitín some 8000 years ago. There are regular buses here from San Luis (AR$13, 2½ hours), passing through Carolina (AR$4, 30 minutes).
