9. Zadar, Croatia

With fewer tourists than Dubrovnik, Zadar feels like a hidden gem where you can mingle with locals and explore Roman and Venetian ruins. Located along Croatia's Dalmatian Coast, the city also features stunning seaside views and a famous "Monument to the Sun," the ultimate spot to see one of the best sunsets in the world (which also doubles as a solar-powered public dance floor).
