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.

Fuente de la Reina, modest in terms of flow, but with historical importance. This fountain has satisfied numerous travelers since ancient times.

What is the best time of year for mountain biking in Real Sitio de San Ildefonso?

Where can I find parking for mountain bike trails in Real Sitio de San Ildefonso?

Many trailheads, especially those near popular starting points like Valsaín, La Granja, or Boca del Asno, typically offer designated parking areas. Given the popularity of the Valsaín pine forest, arriving early, particularly on weekends, is recommended to secure a parking spot.

Are there any dog-friendly mountain bike routes in the area?

While the guide doesn't explicitly list dog-friendly routes, many natural trails within the Valsaín pine forest and less technical forest tracks are generally suitable for dogs, provided they are kept under control.
