Canfranc Station looks like a massive French palace got dropped right into a narrow mountain valley! Nicknamed the "Titanic of the Mountains," this huge Beaux-Arts station opened in 1928 and has a crazy history packed with WWII spy networks and secret gold shipments. It fell into quiet, ghostly ruins for decades after cross-border trains stopped in 1970, but it recently got an epic second life. The whole place was restored into a luxury hotel.

Sitting right on the Spanish side of the border in Aragon, Candanchú is the oldest ski resort in the whole country. Classic mountain-town charm.
