The gorge is part of the La Yecla and Sabinares del Arlanza protected natural space.
The Mataviejas River creates a vertical erosion pattern that has sliced through the limestone massif over millennia.
The narrowest points of the canyon are so tight that sunlight struggles to reach the bottom of the gorge.
The area is an important nesting ground for Gyps fulvus, the Eurasian griffon vulture.
The construction of the walkway infrastructure allows access to a sector of the canyon that was previously inaccessible to hikers.
Desfiladero de La Yecla is a narrow limestone gorge carved by the Mataviejas River located in the Sierra de la Demanda. The site features a series of suspended walkways and bridges bolted directly into the canyon walls, allowing visitors to walk through the deepest section of the fissure. The gorge spans approximately 600 meters in length, with walls reaching heights of up to 100 meters while narrowing to less than 2 meters in width at several points. The limestone formations exhibit distinct erosive patterns and karst geological features. It serves as a protected natural area that supports nesting populations of griffon vultures. The walking route is integrated into the regional road network via a series of tunnels and pedestrian paths.
The metal bridge sections halfway through the walk, looking upward toward the narrow strip of sky between the limestone walls.
Wear footwear with good grip as the walkway metal surfaces can become slippery in damp conditions.
If arriving by vehicle, use the designated parking area near the entrance rather than stopping on the road shoulders.
Bring a light jacket even in summer, as the temperature inside the deep gorge is significantly lower than on the plateau.
Attempting to photograph from the main road tunnel, which has heavy traffic and no pedestrian shoulder.
