Head out on foot alongside a specialized guide, as you enter the Pile Gate and traipse along Dubrovnik’s medieval stone walls past historic fortresses before enjoying free time in the buzzing Stari Grad district. Stand before Pile Gate, the 14th-century main entrance to the city’s walled-in Old Town, and listen through a sightseeing headset to your guide’s insightful commentary. Walk across a stone bridge and then climb to the top of a series of defensive medieval walls, hearing tales of this Mediterranean town’s maritime trading prowess dating back to the 13th century. Take in sweeping views atop Minceta Tower and learn about St. John Fortresses’ pirate defense system before glimpsing Fort Bokar, believed to be the oldest casemented fort in Europe. As you make your way along the limestone-paved streets of Stari Grad (Old Town), you’ll pass an impressive mixture of Gothic, Renaissance and Baroque-style churches, monasteries, and palaces. In the lively city center along Stradun, the town’s most famous street, you’ll spend about an hour’s time at your leisure. Here you’ll find a prime gathering space lined with galleries, coffee bars, restaurants and souvenir shops aplenty.
