Cajón del Maipo is a vast canyon carved by the Maipo River and its tributaries. Located in the Chilean Andes, only 50–70 km from the city center of Santiago, it is one of the largest and most accessible natural areas near the capital. The region encompasses several small towns including San José de Maipo, San Alfonso, El Ingenio, and Baños Morales, each offering unique landscapes and cultural experiences.
The geography of Cajón del Maipo is shaped by millions of years of volcanic and glacial activity, creating steep cliffs, mountain ridges, valleys, waterfalls, and mineral-rich hot springs. Standing at altitudes ranging from 900 meters to over 6,000 meters above sea level, the canyon offers a diverse climate and ecosystem. This makes it ideal for outdoor activities such as hiking, birdwatching, rafting, and photography.
The region is not only a major tourist attraction but also a crucial ecological and hydrological zone for central Chile. It hosts a significant portion of Santiago’s freshwater reserves and features native species like the Andean condor, foxes, guanacos, and endemic flora unique to high-altitude environments. Ecologists identify Cajón del Maipo as a strategic conservation area, especially as climate change accelerates glacier melt and impacts water cycles.
