The park contains the ruins of the 12th-century Romanesque Hermitage of San Frutos, built on a cliff overlooking the river.
It holds the largest colony of griffon vultures in the entire Spanish peninsula.
The canyon was formed by the river cutting through Jurassic limestone layers.
Evidence of human occupation in the caves dates back to the Bronze Age.
The park is classified as a ZEPA (Special Protection Area for Birds) under European Union standards.
The Duratón river flow is controlled by the Burgomillodo reservoir, which influences the water levels through the gorge.
Hoces del Río Duratón is a natural park situated in the province of Segovia, featuring a dramatic limestone canyon carved by the Duratón River. The landscape consists of deep, winding gorges that reach depths of up to 100 meters. The area serves as one of the most significant nesting sites for griffon vultures in Europe. Several centuries-old hermitages, including the Ermita de San Frutos, are located on the canyon cliff edges. The park is a protected space managed by the Junta de Castilla y León. Visitors can access the area via the town of Sepúlveda, which serves as the primary gateway to the park. The canyon environment supports a diverse ecosystem including golden eagles and peregrine falcons. Trails are marked throughout the plateau to provide views of the river meandering below.
The viewpoint at the Ermita de San Frutos provides the widest panoramic view of the canyon's signature river bends.
Bring high-quality binoculars for birdwatching as the nesting cliffs are often at a distance.
Register in advance at the park interpretation center if you intend to kayak or use watercraft during the permitted season.
Wear sturdy, broken-in hiking boots as the terrain is rocky and uneven.
Do not attempt to descend the canyon walls outside of authorized paths as the terrain is unstable and dangerous.
Access to certain river stretches is restricted from January to July to protect the griffon vulture nesting season.
Maintain silence near nesting areas; stay strictly on marked paths to prevent erosion and disturbance to wildlife; dogs must be kept on a leash.
