The canyon provides approximately 70% of the drinking water for the city of Santiago.
It is home to the El Yeso Dam, which sits at an elevation of 2,500 meters above sea level.
Geological surveys of the area have identified significant fossil deposits from the Jurassic and Cretaceous periods.
The Baños Morales springs contain high concentrations of minerals like iron, sodium, and magnesium.
The area features a unique 'esclerófilo' forest ecosystem, which is endemic to central Chile.
It was used by early indigenous groups, including the Picunche and Mapuche people, as a seasonal passage through the Andes.
The canyon floor has a significantly lower temperature than the Santiago basin due to its elevation and river cooling effects.
Cajón del Maipo is a deep canyon carved by the Maipo River, located in the Andes mountains within the Santiago Metropolitan Region. The area serves as a primary source of fresh water for the Chilean capital. It is characterized by rugged geological formations, hanging glaciers, and high-altitude Andean terrain. Notable features include the El Yeso Dam, a reservoir that supplies water to Santiago, and the Baños Morales hot springs. The region offers diverse microclimates, transitioning from semi-arid scrubland at lower elevations to alpine tundra at higher altitudes. It is a hub for adventure tourism, specifically trekking, mountaineering, and kayaking. Several protected areas, such as the El Morado Natural Monument, are located within the canyon limits. The canyon's accessibility from San José de Maipo makes it a central location for exploring the central Chilean cordillera.

Bring layers of clothing, as temperatures drop significantly as you gain elevation toward the high Andes.
Ensure your vehicle is in good condition, as many access roads to secondary canyons are unpaved and rocky.
Carry sufficient water, as hydration is critical in the high-altitude, dry mountain air.
Attempting to reach the El Yeso Dam or high-mountain trails in winter without a 4WD vehicle and proper snow equipment.
Access to high-altitude sectors like El Morado Natural Monument may be restricted during winter months due to heavy snowfall and avalanche risk.
Practice 'Leave No Trace' principles; pack out all trash, as there are limited facilities in remote areas.
