Hidden Global Cities That Are Under the Radar but Full of Character

14. Kotor, Montenegro – The Adriatic’s Secret Fairytale Town

Nestled in a fjord-like bay along the Adriatic coast, Kotor is a medieval gem that rivals the beauty of Dubrovnik but without the overwhelming crowds. Cobblestone streets wind through Venetian-era stone buildings, leading to hidden squares, charming cafés, and centuries-old churches. The climb to Kotor Fortress rewards visitors with breathtaking panoramic views of the bay, making it one of the most spectacular sights in the Balkans. Beyond its medieval walls, Kotor is a haven for sailing, hiking, and exploring nearby coastal villages like Perast, home to the mystical island of Our Lady of the Rocks. Best time to visit: April–June or September–October (to avoid peak summer crowds).
