At 2700 meters above sea level, Puente del Inca is a rock formation that forms a natural bridge over the Las Cuevas River, a tributary of the Mendoza River in Mendoza Province, Argentina. The curious Puente del Inca, along with the ruins of the old and abandoned thermal baths hotel, has become a prominent tourist spot, now considered a provincial protected Natural Area.

This geomorphological curiosity is about 48 metres long, 28 wide and 8 thick, and is suspended 27 metres above the river. Throughout the year, a series of stalactites hang from the bridge. In winter, due to the very low temperatures recorded, the bridge's landscape is further enriched with suggestive ice needles.
