I know of few cities that combine beach and city as well as Santander. You can sit on the sand of any beach in Santander and it seems like you're miles from the city just lounging around with other tourists and beach-goers who are just there to enjoy the sun and the waves of salty water that heal the body and ease the mind.
But as soon as you leave the sand, you discover large urban avenues lined by clean, white sidewalks and asphalt.
Take a few steps from the beach and your swimsuit and sarong become increasingly out of place. The north is elegant by nature and the streets of Santander are sober but with a touch of character.
