The bridge was built in the 11th century and served as an important crossing point on the old road to Castile. It crosses the Cadagua River and is one of the city's landmarks. The bridge consists of three arches and has a Gothic tower added in the 15th century. This tower was formerly used to collect tolls.

Very interesting stretch of cycle path along the Ria. There is a lot to see along the route to and from Bilbao.

The best-known image of Balmaseda, and it is right. A pleasure to go through.

From this point on the road you can see the views of the center of Villabasil and where you can see the Montes de la Peña behind them.

One of the most publicized civil constructions in Bizkaia. Its charm has always been highly appreciated by painters, photographers and travelers. The footbridge joins the two banks of the Cadagua River where the neighborhoods of El Cristo and San Lorenzo are located, respectively, a place that occupied a modest Jewish aljama until 1492. It has a cobbled pavement.
