25. BUDAPEST, HUNGARY
Therapeutic thermal baths, acclaimed museums and traditional Hungarian fare are just some of the things you’ll find in this Eastern European city. And thanks to Budapest’s abundance of Romanesque- and Gothic Revival-style architecture, the city is just as beautiful to look at as it is exciting to experience. For some of the best vistas of Budapest (and a view of one of the city’s two UNESCO World Heritage sites), take the funicular from the banks of the Danube River to Castle Hill.
