The path was specifically commissioned by King Charles III to create a dedicated fishing route along the Eresma River.
It is integrated into the larger Valsaín Forest, a site that was once the primary hunting ground for Spanish monarchs.
The trail features remnants of old stone weirs and dams designed to manage water levels for royal fishing purposes.
The path connects directly to the complex hydraulic system that supplies water to the famous fountains of the Royal Palace of La Granja.
The route passes through high-altitude Scots pine stands (Pinus sylvestris) which are among the most important in the Iberian Peninsula.
The Senda de las Pesquerías Reales is a historic riverside path located within the Royal Site of San Ildefonso in Segovia, Spain. Commissioned by King Charles III in the 18th century, the trail follows the Eresma River, which was historically stocked with trout for royal fishing excursions. The path spans approximately 4.5 kilometers, connecting the gardens of the Royal Palace of La Granja de San Ildefonso to the Valsaín forests. It features stone-paved segments and wooden footbridges constructed to facilitate royal access to the riverbanks. The route serves as a significant example of Bourbon-era hydraulic engineering and landscape design integrated with native Scots pine forests. Vegetation along the path includes riparian species such as willow, ash, and poplar, alongside the dense canopy of the surrounding Sierra de Guadarrama mountains.

Wear sturdy hiking shoes with good grip, as parts of the path near the riverbank can be slippery or uneven.
Carry sufficient water as there are no public amenities or kiosks along the forest stretch of the trail.
Bring binoculars for wildlife spotting, as the Eresma river corridor is a habitat for gray herons and kingfishers.
Do not attempt to swim in the Eresma River, as currents can be unpredictable and the water remains extremely cold year-round.
Maintain silence to avoid disturbing local wildlife and strictly adhere to 'Leave No Trace' principles in this protected forest area.
