Puente del Inca, located in Mendoza Province, Argentina, is a natural rock bridge spanning the Las Cuevas River in the Andes Mountains. Visitors can view the arch from designated viewpoints, explore the surrounding landscape, and photograph the mineral-rich formations and nearby ruins. The site is notable for its vivid colours caused by mineral deposits from hot springs, as well as the remains of an early twentieth-century spa destroyed by a landslide, reflecting both geological processes and historical use of the area.
