Stylized the "Inca's Bridge" in English, Puente del Inca is both a natural bridge stretching over the Vasca River and a hot springs found nearby. Research into the area suggests that the bride formed after the river froze and sediment built up atop of it - thus, when the river melted, a bridge had formed from the solidified rock. Today, the hot springs and bridge are reachable through small train station, allowing easy access to the thermal resort and spa located here.
