Sistema del Cerro del Cuevón is a karst cave system in Cabrales, Asturias. It consists of two interconnected chasms, and is located in the central massif of the Picos de Europa. At 1,589 meters deep, and 4.3 miles (7 km) in length, it is the deepest cave in Spain and the 8th deepest in the world. In 1998, a team of French and Spanish speleologists first reached the bottom of the cave system.

Description
The cave system has two entrances, both pits:


 * Torca del Cerron del Cuevón, also called T-33, is a pit located at 2,019 meters above sea level. It is considered difficult to descend because there is are no ledges to rest on, and it takes 3 days to descend. Inside there is an underground river called the Margebralo River.


 * Torca de las Saxifragas, also called TR-2, is a pit located at 1,590 meters above sea level, at the bottom of the Cuesta del Trave. It connects to Torca del Cerron del Cuevón.
