The canyon was famously featured in several episodes of the nature documentary series 'El Hombre y la Tierra' hosted by Félix Rodríguez de la Fuente.
The limestone formations throughout the canyon exhibit distinct fluvial erosion patterns caused by the Río Dulce over millennia.
Pelegrina Castle, located within the park, dates back to the 12th century and was once a fortress for the Bishops of Sigüenza.
The park's diverse terrain hosts a rare mix of Mediterranean and Euro-Siberian vegetation zones.
The Río Dulce is a tributary of the Henares River, which flows through the provinces of Guadalajara and Madrid.
Parque Natural del Barranco del Río Dulce is a protected river canyon landscape defined by deep limestone gorges carved by the Río Dulce. The park spans over 8,000 hectares, encompassing diverse ecosystems including riparian forests, savin junipers, and oak groves. It is recognized as a ZEPA (Special Protection Area for Birds) due to its significant population of raptors, including griffon vultures and golden eagles. The area features a network of well-marked hiking trails, most notably the route connecting the villages of Aragosa, La Cabrera, and Pelegrina. The landscape is marked by unique karst formations, waterfalls, and steep cliffs reaching up to 100 meters in height. The village of Pelegrina contains the remains of a medieval castle overlooking the canyon. The park serves as a habitat for diverse wildlife, including otters and mountain goats. The river itself creates a microclimate that sustains flora distinct from the surrounding dry Castilian plateau.

Wear sturdy, broken-in hiking boots due to the loose limestone gravel on trail paths.
Bring binoculars to spot raptors nesting on the high canyon walls.
Check weather reports before starting, as canyon temperatures can drop quickly if it becomes overcast.
Do not attempt the full canyon hike in the middle of summer without carrying significant water, as shade is intermittent.
Maintain silence to avoid disturbing nesting raptors; stay strictly on marked paths to prevent erosion and habitat destruction.
