Desfiladero de La Yecla is a narrow canyon located in the province of Burgos, in the northeastern part of the autonomous community of Castile and León, Spain.
Tucked away in the northern part of the country, the road through the canyon formed by the Arroyo del Cauce is totally paved. It’s called BU-910. The splendid gorge of limestone cliffs is deep, and you can walk inside in a well-marked walk path, just past the second tunnel exit. The road runs parallel and it crosses the ridge underground through two tunnels, right beneath the gorge. At the end of the second tunnel is the parking lot for the gorge. The walkway is narrow so, if you meet people in the other direction, it is difficult to walk.
With vultures flying overhead, the road through the gorges is 8.4 km (5.21 miles) long, running north-south from Santo Domingo de Silos, famous for its monastery, to Espinosa de Cervera. High risk of rock slides.
