The Pas nature trail.
From Ontaneda to Sarón, a dreamy pathway.
One of the great appeals of the Pas Valleys is the nature trail, a singular path inherited from the old railway line that connected Astillero with Ontaneda. This route begins in the district of Penagos and offers the possibility of walking in a pleasant environment in whatever stage. One can also enjoy bicycle rides, skating or roller blading in a route that is ideal for all the family.
The route kilometre by kilometre
Taking the village of Cabárceno as the starting point, we can go through the regional road 408 until the town of La Helguera where we find the first pedestrian route in the national road N634, that will take us to Sarón. It is a route that give a certain perspective of the high mountains of Pas and Miera. At the village entrance the trail disappears until we pick it up again at the bus station on a route that begins next to Pisueña river and that will take us to the Nestlé factory in La Penilla.
It is usual to accompany this stretch most weekdays by the unmistakable fragance of chocolate and a low-mountain environment, which makes this first stretch of the walk to Puente Viesgo a real pleasure. Once the town of La Cueva is left behind and we then arrive to Pomaluengo, we have the possibility of continuing along the path through the paved road of the nature trail or enjoying a pleasurable journey next to the river, truly recommended for its calmness and its landscape environment.
Once left the village, we return to the paved road which turns into a path that will take us to the first contact with River Pas, arriving at the interesting village of Puente Viesgo. A district that offers many facilities to see and do, particularly the group of pre-historic caves of Monte Castillo.
We start from Puerte Viesgo and rapidly arrive to Penilla, a town that offers amongst its curiosities a scale model of the town done by a neighbour. It is a compulsory stop. Slowly we go into Toranzo Valley, a place of a landscapes, architectural and historical richness that will not leave the visitor unmoved.
A particular place of interest is the Nuestra Señora del Soto Convent located in Soto Iruz dating from 16th century, although its main constructions were made in the 17th c. Don’t miss the landscape environment offering spectacular views and vistas all year round.
As we continue after a long, straight stretch, we will arrive to another landmark : the Aqueduct of Rual Bridge. This modern-ish construction dates from 1885 and had the purpose of supplying clean water to the city of Santander. Later on, we arrive to another of the most recognised points of the Trail, the iron bridge with wooden contours above Pas river. An obvious land one of the places most photographed in the area.
We turn left just after getting off the bridge and go into the last stretch that hugs the riverside with incredible views and a few more surprises, such as a public pool in the village of Ontaneda. The walk finishes at point of interest called Alceda Park, a garden that treasures a great arboreal richness, as well as a pond, a pavilion, zip lines, bar and the historical Spa of Alceda.
