Discover more about Puente del Inca

Puente del Inca, meaning "Inca's Bridge" in Spanish, is a remarkable natural rock formation located in the Andes Mountains of Argentina, Mendoza Province. Situated at approximately 2,720 meters (8,920 feet) above sea level, near the border with Chile, this unique geological feature has captivated visitors for centuries. The bridge spans the Vacas River, formed by mineral-rich thermal springs depositing colorful layers of sediment over thousands of years. These minerals, including iron, sulfur, and calcium carbonate, create a vibrant spectacle of yellow, orange, and red hues. The bridge's name originates from its use by the Incas as a vital passage across the Andes. In the early 20th century, a luxury spa hotel was built near the bridge, attracting visitors seeking the therapeutic properties of the thermal waters. Each room had its own thermal bath, piped directly from the springs. Unfortunately, a landslide destroyed the hotel in 1965, leaving only the ruins of a small colonial chapel. Today, Puente del Inca is a protected area, drawing tourists with its breathtaking views and historical importance. While crossing the bridge is no longer possible due to a partial collapse in 1965, visitors can explore the surrounding area, including the mountaineering cemetery and remnants of the old railway. The site offers a unique blend of natural beauty, geological wonder, and cultural heritage.
