Each European country has its marquee city that attracts the vast majority of travelers—think Rome, Paris, Amsterdam. And all too often, that tourist-pleasing destination is a traveler’s one and only stop.
While I’d never suggest skipping those places entirely, I like to complement them with a visit to the country’s “second city.” In fact, if you have four days to spend in any of these capitals, I recommend cutting your visit a day short to make time for these cities.
