San Vicente de la Barquera

San Vicente de la Barquera needs 1 day: crossing the Puente de la Maza, a medieval 28-arch bridge over the estuary, on one, and climbing to the castle and the Iglesia de Santa María de los Ángeles, atop the town with views of the Picos de Europa, on the other. June-September brings the mildest weather. It's mid-priced for Cantabria. It's one of the towns with the most beaches on the Cantabrian coast, and its combination of sea, estuary and mountains -with the Picos de Europa visible from the coast on clear days- is the most complete in the whole region.
