A descent from the mountains of Palencia to the heart of Cantabria

One of the most beautiful routes in the north, winding down from the mountains of Palencia to the heart of Cantabria through the spectacular Hoces de Bárcena. The road runs parallel to the River Besaya, plunging into a deep valley where lush green vegetation and the viaducts of the Alar railway create a scene where engineering and nature are perfectly integrated. Travellers pass through charming villages such as Bárcena de Pie de Concha or the gorges of Las Caldas, where the rock faces seem to embrace the road. It is a thrilling descent that allows you to enjoy traditional mountain architecture and the serenity of a route which, bend by bend, takes us from the austere highlands to the light of the Torrelavega valley.
