Overtourism has quietly reshaped how a lot of people plan European trips. Venice now caps daily visitors, Barcelona has restricted new short-term rentals, and Amsterdam actively discourages certain kinds of tourism altogether. None of that means Europe is less worth visiting — it means the smartest trips in 2026 are heading to the cities picking up the overflow, often with better prices and shorter lines to show for it.
1. Porto, Portugal
Porto gets a fraction of Lisbon’s tourist numbers despite offering nearly the same combination of riverside views, historic tile-covered buildings, and genuinely excellent, affordable food. Port wine cellars across the river in Vila Nova de Gaia offer tastings at a fraction of what a comparable experience costs in more famous wine regions. If you’re already comparing flight strategies for a trip like this, our guide on finding cheap flights without using a travel agent pairs well with Porto specifically, since it’s served by budget carriers from most major European hubs.
2. Ljubljana, Slovenia
Slovenia’s capital is small enough to walk end to end in under an hour, with a car-free old town, a dragon-guarded bridge, and a castle overlooking the whole city from a hill. It’s also one of the least crowded European capitals, making it an easy add-on to a longer Balkans or Central Europe itinerary rather than a standalone destination.
3. Ghent, Belgium
Most travelers pass through Belgium via Brussels or Bruges, leaving Ghent — arguably more charming than either — comparatively empty. Medieval architecture, a genuinely lively student population, and some of the best Belgian beer bars outside Brussels make it worth the short train detour most itineraries skip.
4. Košice, Slovakia
Eastern Slovakia rarely makes anyone’s first-time-in-Europe list, but Košice offers a walkable historic center, a genuinely unusual singing fountain, and prices that feel like a different decade compared to Western Europe. It’s a practical base for exploring Slovakia’s mountain regions without the crowds found further west.
5. Matera, Italy
Matera’s cave dwellings, carved directly into limestone cliffs and inhabited continuously for thousands of years, earned it European Capital of Culture status, yet it still sees far fewer visitors than Rome or Florence. It’s remote enough that a rental car genuinely helps, but the payoff is a townscape that looks almost otherworldly at sunset. Travelers plotting a longer Italy route often pair this with weight-loss-friendly travel planning around walkable itineraries, since Matera’s hilly, stair-heavy layout is naturally activity-dense.
6. Aarhus, Denmark
Denmark’s second city gets overshadowed by Copenhagen entirely, despite having its own strong food scene, a genuinely excellent art museum, and a compact enough footprint to see most of it in two or three days. It’s also noticeably cheaper than the capital for accommodation, without sacrificing much of what makes Danish cities appealing.
7. Plovdiv, Bulgaria
Continuously inhabited for roughly 6,000 years, Plovdiv’s old town sits directly on top of a well-preserved Roman amphitheater still used for concerts today. Bulgaria overall remains one of the least expensive countries in the EU to visit, and Plovdiv specifically offers more historic density per euro spent than almost anywhere else on this list.
8. Utrecht, Netherlands
Utrecht has the canals, the bikes, and the historic center people associate with Amsterdam, minus the crowds and the city’s more recent tourism restrictions. It’s a 30-minute train ride from Amsterdam itself, making it a realistic day trip or a smarter base for anyone wanting the classic Dutch-city experience without competing for sidewalk space. If travel insurance is on your planning checklist for a multi-country trip like this, it’s worth reading through what a policy actually covers and when you need it before booking anything non-refundable.
A Ninth Honorable Mention: Sibiu, Romania
Transylvania’s Sibiu often gets overshadowed by Bran Castle day-trippers passing through without stopping, but its pastel baroque main square and the eerie “eyes” built into surrounding rooftops make it worth a night or two on its own. It’s also one of the more affordable stops on this entire list, even relative to already-inexpensive Eastern Europe generally.
