Beautiful place to enjoy the Pas river. It has a small fisherman's feel surrounding the river and a great wooden bridge with nice and quiet views of it.

One of the most accessible cycling greenways in Cantabria. It runs through the Valles Pasiegos crossing the emblematic Puente Viesgo. It is a very rich route, covering places such as the Collegiate Church of Santa Cruz in Socobio, the Church of the Assumption in Acereda, the Monastery of Nuestra Señora Del Soto in Iruz or the Spa and Town Hall of Puente Viesgo or the Historical-Artistic Complex of Alceda among others.

Also known as El Puente Rual, the aqueduct is next to the Vía Verde del Pas. It was built in 1885 in order to supply drinking water to the city of Santander. It is an ideal place to take a short break – there is shade, benches and tables. In front there is a bar and a fountain.

The old Santander-Ontaneda railway had an important stop in Puente Viesgo. Once its route disappeared, it was recovered as a place for walks and a bike path. From the spa, a straight path begins that takes you first to the old train station, a curious railway construction that can only be seen from the outside, and you arrive at the place where the "La Reyerta" locomotive recalls past times. Built in Munich in 1912, its machinery has been taken care of and restored, now on one side of the old track that it used. You can go up and feel like a driver or take pictures.
