Barcelona

Barcelona is a working port that happens to own a beach and an unfinished cathedral. The Eixample grid runs dead straight from the hills to the water, which is why the sea gets all the way into the city most afternoons, and why the old town smells of salt rather than traffic by five.

Two hours and five minutes from London, four days a week, on all three cabins. Short enough that the flight is not the point — long enough that arriving still feels like somewhere else.
