7 underrated European cities you need to visit

While tourism is on the rise in Hungary's capital city, it's safe to say that it still remains a somewhat well-kept secret. The fourteenth largest city in Europe, Budapest is certainly one of the most beautiful cities in the world, boasting amazing museums, churches, and scenic views of the Danube.

Paris may be the city of love, but Strasbourg, located just over two hours from the capital by train, serves as the official seat of the European Parliament and showcases the exquisite beauty of the Alsace region. Located close to the German border, Strasbourg's city center is an official UNESCO World Heritage site and features architecture and culture that's a charming mix of both German and French.

Amsterdam gets plenty of tourists, and for good reason, but just a quick 36-minute train ride away is Rotterdam, Europe's largest port and the home of the insanely cool Cube Houses. It also boasts the delicious and impressive indoor market, Markthal. The city is currently "riding a wave of urban development, redevelopment and regeneration," according to Lonely Planet, making it an exciting place to check out.

Prague has been a long-time favorite of travel lovers, and while you should certainly check it out if you're in the Czech Republic, don't neglect a trip to Karlovy Vary, a spa town in West Bohemia that's every bit as charming as its capital. Founded in 1350, Carlsbad, as it's also called, is famous for its numerous hot springs, which you can visit. It also features "elegant colorful architecture."

Another city flying seriously under the radar, Bruges — located less than an hour from Brussels by train — serves as the capital of the Flemish region of Belgium and its busy city center is another UNESCO World Heritage site. It's a city rife with canals, making it a beautiful place to stroll around on a sunny day. And, as one of the "best-preserved" medieval towns, you're sure to get a dose of historical education while you're at it.

Poland in general has been growing as a tourism hub in recent years, with its historic city Krakow drawing a record number of visitors last year. However, venture north (roughly five and a half hours via train) to the Baltic coast and there you'll find Gdansk, the sixth largest city in the country. Gdansk is home to the Westerplatte war monument, the Long Market (a square that acts as the "heart of the city"), and a unique ambiance which makes it well worth the trip.
