European Cities Americans Frequently Underestimate

Porto sits at the mouth of the Douro River and punches well above its weight for a city of roughly 300,000 people. Its riverfront district, Ribeira, is a UNESCO World Heritage Site, and the city's azulejo tile facades — ornate hand-painted ceramic panels covering churches and train stations — make even a casual walk feel like a gallery visit.

The wine culture here centers on Port wine, produced in the Douro Valley and aged in lodges across the river in Vila Nova de Gaia. Beyond wine, Porto's restaurant scene has matured significantly, with chefs building on regional seafood traditions and generations-old recipes. Getting there is straightforward: a direct transatlantic flight to Lisbon followed by a comfortable three-hour train ride, or a direct flight into Porto's Francisco Sá Carneiro Airport from select US cities.

Most visitors to Belgium make a beeline for Brussels or Bruges. Ghent — larger and livelier than Bruges, less crowded than Brussels — tends to get bypassed entirely, which is a significant oversight. The medieval city center is intact and beautifully preserved, anchored by the Gravensteen (a 12th-century castle that sits improbably in the middle of a modern city) and the St. Bavo's Cathedral, home to the Van Eyck altarpiece considered one of the most important paintings in Western art history.

Ghent is also a university city, which gives it an energy and affordability that pure tourist destinations often lack. Its canal network is quieter than Amsterdam's but no less atmospheric, and the local beer culture is serious without being exclusionary.

Slovenia's compact capital is one of Europe's most livable cities and, by many accounts, one of its most beautiful. A medieval castle overlooks a baroque old town bisected by the Ljubljanica River, where outdoor café seating lines both banks. The city is walkable, cycle-friendly, and notably low on the mass-tourism noise that defines more famous capitals.

Ljubljana also serves as a practical base: Lake Bled is less than an hour away, the Julian Alps are accessible for day hikes, and the Adriatic coast is reachable by afternoon. For a city this compact — the historic core is easily covered in a day of walking — the surrounding daytrip options are extraordinary.

Athens dominates most Greece itineraries, understandably so — but Thessaloniki, Greece's second city, makes a compelling case for its own visit. The food culture here is widely considered the richest in Greece: the city has a long Ottoman and Byzantine heritage that shows up in its markets, pastries, and mezze traditions in ways Athens doesn't fully replicate.

Archaeologically, Thessaloniki is remarkably dense. Roman-era structures including the Arch of Galerius and the Rotunda sit alongside Byzantine churches (several of them UNESCO sites) and a waterfront promenade that locals actually use. The city's energy is more relaxed and authentically Greek than the capital's tourist-heavy center.

Tallinn's medieval old town is among the best preserved in all of Northern Europe, and it made the UNESCO list back in 1997. What surprises most first-time visitors is how intact and non-commercialized the core still feels — cobblestone streets, Gothic town hall, defensive towers, and a hilltop Toompea neighborhood that overlooks the Baltic Sea.

Estonia is also surprisingly tech-forward for a country of its size; it pioneered e-governance and has a startup culture that makes it feel more dynamic than the fairy-tale architecture suggests. Winters are cold and dark, but summer brings long days and a festival season that energizes the whole city. Direct budget flights from several European hubs make Tallinn easy to add to a broader Scandinavian or Baltic itinerary.

Before the Guggenheim Museum opened in 1997, Bilbao was an industrial port city in Spain's Basque Country. The museum's arrival is now urban planning legend — a textbook case of how architecture can catalyze city transformation. But Bilbao has grown well beyond that story. The Casco Viejo (old quarter) has some of the best pintxos bars in the country, and the Basque culinary tradition more broadly gives the city a food reputation that rivals San Sebastián at a lower price point.

The city's riverfront regeneration project is genuine and ongoing, and its public transit — including a metro designed by Norman Foster — is a pleasure to use. Day trips to the coast at Getxo or to the cliffside village of Gaztelugatxe are easily done. For travelers who've done Madrid and Barcelona, Bilbao is a natural and rewarding next step.
