Trespaderne
Highlight • Trail
74.5 kilometers. 480 positive meters.
The third day of the gravel adventure has little description and no possibility of confusion, it follows the same section of the Santander-Mediterranean Natural Trail as the first stage to the city of Burgos. The Trespaderne exit passes again over the medieval bridge and connects with the railway line at the old station, equipped with benches and a recreation area. Now there are 350 meters of positive slope to the Peñahorada pass, but you barely notice it, the surface is magnificent and the kilometers fly by. The natural fantasies of the Ebro and Oca canyons end in Oña, gateway to La Bureba and its peaceful villages nestled between hills of saline marl and primitive volcanic materials, giving the landscape a particular atmosphere of shapes, reliefs, colors and textures in the Homino River plain.
The Poza de la Sal detour is highly recommended, it is close to the old railway station, it would be unforgivable to pass through the door and not stop to see this medieval town declared a Historical-Artistic Site in 1982, which was also the birthplace of the naturalist Félix Rodríguez de the fountain. The salt flats are an extraordinary set of industrial architecture at the foot of the Páramo de Masa with notable geological, ethnographic, historical and cultural interest. They have been exploited since the Iron Age until recent times. And a walk through the historic center is also essential, an interesting example of popular architecture and medieval streets staggered around the castle hill, with remains of the original wall and several doors that gave access to the interior of the town, the best known. and monumental is the Arco de la Concepción or Puerta del Conjuradero, between Plaza Nueva and Plaza Vieja.

The trip continues through the Burebana plain to the Peñahorada pass and the tunnels that save the La Serrezuela canyon, entering the path into the peasant plain of the Ubierna valley. The passage through Sotopalacios always brings excitement because the old railway does not cross many towns, it always passes glancingly. In the Villalonquéjar Industrial Park you have to change the outbound route slightly to make it easier to go through the roundabouts and enter the bike lane that leads directly to La Estación without passing through the historic center. The bike path is well indicated outside the street carriageways, it passes over the Arlanzón bridge and continues parallel to the river to the starting point in the gardens of the old North Station, where we end the intense gravel bikepacking trip. of three days in the north of the province of Burgos.

Tips from the Community
It is worth visiting the hermitage of Santa María de la Hoz, in the town of Tobera. To do this, we will cross a medieval bridge of Roman origin that spans the Molinar riverbed. The temple, almost embedded in a large rock, dates from the 13th century, features both Romanesque and Gothic elements, and has a portico with arches that offers good views of the surroundings. At its feet stands a second, tiny hermitage from a later date – the 17th century – which houses an altar dedicated to the Cristo de los Remedios.
