El Cajas National Park, located in the Western Cordillera of the Andes approximately 33 kilometres northwest of Cuenca, Ecuador, is a high-altitude páramo ecosystem that functions as a massive hydrological "sponge."
Its name, derived from the Quichua word caxa (cold) or from the box-like shape of its glacial valleys, describes a 28,544-hectare landscape dominated by stark geological formations and pristine water systems.
1. Geographical framework and hydrological value
Molded by intense glaciations, the park’s relief features "U-shaped" valleys and a lacustrine system unparalleled in the region.
- The lacustrine complex — the park houses approximately 786 bodies of water, making it a Ramsar Site of global importance. These lagoons act as natural reservoirs that regulate the drinking water supply for the city of Cuenca and feed vital hydroelectric plants.
- The continental divide — at the sector known as Tres Cruces (Three Crosses), situated at 4,200 metres above sea level, the waters take two opposite paths: some flow toward the Pacific Ocean via the Yanuncay and Tomebamba rivers, while others head toward the Atlantic Ocean through the Amazon basin.
- Altitude — elevation ranges from 3,152 m to 4,445 m (10,341 to 14,583 ft).
2. Biodiversity and ecological niches
El Cajas is a high-altitude laboratory of evolution. While the landscape is dominated by straw-like pajonal grasses, its forest zones harbor biological treasures.
- Polylepis forests — these unique formations, locally known as "paper trees" (árbol de papel), grow on protected slopes. The Polylepis reticulata thrives at altitudes where most trees cannot survive, creating a microclimate for rare bird species.
- Specialized fauna — a critical sanctuary for the Andean Condor (Vultur gryphus). Visitors can also spot the carunculated caracara, the blue-billed duck, white-tailed deer, the páramo wolf and the elusive spectacled bear.
3. Archaeology and the Inca Trail
The value of El Cajas transcends biology; it is a vital historical corridor for the Cañari and Inca cultures.
- Qhapaq Ñan — a segment of the Great Inca Road crosses the park, historically connecting the highlands with the coastal lowlands. The ruins of Paredones de Molleturo, located on the western flank, suggest the area served as a strategic administrative and military control center for the empire.
4. Logistics and strategic access
For those planning an excursion, the park’s proximity to urban centres offers a significant logistical advantage.
- Urban proximity — the park is less than an hour from the city. Notably, Hotel NASS Pinar del Lago is the closest hotel in Cuenca to the park. Located in the Puertas del Sol neighborhood on Ordóñez Lasso Avenue, it serves as the ideal base for high-altitude expeditions, allowing for a swift transition from the city’s comfort to the rugged beauty of the páramo.
