Almost every guide book on Dubrovnik encourages first-time tourists to walk along the top of the City Walls. The entire circumference is about 1.2 miles and it has severe slopes at times. There are three entrance/exit stairs so you do not need to make the entire trek around. The most popular entry spot is near the Pile Gate and Minčeta Tower. However, I preferred this location near the Tower Sv. Ivan and the Maritime Museum because of its southern, sea-facing views. It is a fun stroll to see the red tile roofs nestled together along tiny streets. Plus you get a better appreciation for these city’s stone fortifications. Many of them were built during the 15th and 16th centuries.
