It is a unique cave in South America due to its size and kind. It dates back from a million years and unfolds an extravagant natural architecture featuring several levels, domed corridors and disconcerting huge stalactites and stalagmites. Tour guide assistance is recommended.
This is a geological formation of impressive features, both for its magnitude, and because of the ways that salt and water have generated stalactites, stalagmites, robes, veils, columns, stony corals, chimneys and countless galleries that can be appreciated in all its magnitude through the strategic lighting and experienced guides who accompany the tourist. The time required to tour the whole cave is almost three hours and can be done at any time of the year. It is currently a provincial reservation.
