The Saint James’s Way winds through Muskiz, a town bordering Cantabria that boasts some of the most stunning coastal scenery in Biscay. Here, the pilgrimage route follows the Itsaslur and Piquillo Greenways, former railway lines that once served the area’s thriving mining industry. This stretch is of great cultural, environmental and scenic value. The Barbadun estuary in Pobeña is a protected Natura 2000 site, complemented by a spectacular coastal promenade.
