The meadow of the old Fuenfría inn is a privileged place for stopping and resting, from where you can see extraordinary landscapes such as Siete Picos and the Bola del Mundo.

Beautiful place to the left of the Fuenfría valley. A hill that reaches a height of 1750 m. and which is located between Peña Bercial and Peña del Águila.

La Pradera de la Fuenfría is a peaceful place with beautiful surroundings, located under Las Camorcas. These mounds are the continuation of the abrupt 90-degree turn made by the La Peñota and Montón de Trigo rope, closing the majestic valley of La Acebeda to the east. In this environment, you can find historical remains and experience the natural beauty of the area.
