Cantabrian Maritime Museum · optional extension

The Cantabrian Maritime Museum invites you to see the sea as more than scenery. Its collections bring together marine life, fishing, history and technology: behind an attractive bay lie work, knowledge and ways of living. The aquarium adds another scale to the visit, allowing you to pause before species usually hidden beneath the water. Treat this as a visit in its own right rather than a quick stop between monuments, and allow time for the galleries. It lies east of the centre, extending the walk towards Los Peligros. Check admission, opening arrangements and fares beforehand, and consult urban transport for your return.
