Santander is linked year-round to Plymouth, England, by a twice-weekly car ferry run by Brittany Ferries. Travel agencies in Spain and England have details; book at least six weeks in advance in summer, as boats fill up fast. Another such option is the twice-weekly ferry between Bilbao and Portsmouth run by Ferries Golfo de Vizcaya. The trip takes about 24 hours. For ferries out to Vigo and points west, Vapores Suardiaz runs carriers during the summer.
