The Maipo River is the principal water supply for the seven million residents of Santiago.
The canyon serves as a geological transition zone between the Central Valley and the High Andes.
The area features a unique microclimate that allows for the cultivation of local produce despite the high altitude.
The name 'Cajón del Maipo' refers specifically to the upper basin of the Maipo River where it cuts through the mountain range.
El Morado is one of the few places in central Chile where visitors can observe active glacial processes at relatively accessible altitudes.
Cajón del Maipo is a sprawling canyon and river basin located in the Andes mountains, Southeast of Santiago. It serves as a primary source of fresh water for the Santiago Metropolitan Region, supplied by the Maipo River and its tributaries. The terrain is characterized by high-altitude volcanic landscapes, jagged rock formations, and glacial valleys. It is a major hub for outdoor recreation including hiking, white-water rafting, and horseback riding. The elevation varies significantly, reaching up to 5,000 meters in higher Andean passes. The region is home to the El Morado Natural Monument, which contains several glaciers and high-altitude lagoons. Geothermal activity is present in the area, manifesting in various natural hot springs and mineral-rich thermal pools. The landscape is primarily composed of igneous rock formations resulting from historic volcanic activity in the Andean mountain range.
The edge of the Embalse El Yeso reservoir provides a clear reflection of the surrounding Andean peaks against the turquoise water.
Bring layers of clothing as temperatures drop rapidly once the sun sets behind the canyon walls.
Ensure your vehicle has proper braking systems and check tire pressure, as the terrain requires steep, winding mountain driving.
Carry plenty of water and hydration supplies, as the high-altitude air causes faster dehydration than at sea level.
Attempting to reach the highest mountain passes without a 4x4 vehicle or local mountain guide, especially after rainfall or during winter months.
Road access to higher mountain sectors like Baños Morales or El Yeso may be restricted or closed during heavy winter snowfall.
Practice 'Leave No Trace' principles, as the area is a vital watershed; refrain from off-trail hiking to protect fragile Andean flora.
