Valencia

As far as port cities go, Valencia is one of the most impressive ones, not just in Europe, but also the whole world. It’s the third-largest city in Spain, is nothing short of surreal, and best explored on a bike.

Lovers of architecture will have a vacation of a lifetime in this metropolis. One of its most striking traits is that it has numerous futuristic-looking structures in its famous City of Arts and Sciences complex, where you’ll find educational institutions like a planetarium, a massive aquarium, and an interactive museum. There are also dashes of its medieval past here and there, preserved in structures like the Valencia Cathedral and the Museum of Fine Arts.
