Dubrovnik's City Walls are the longest and most complete in Europe. They also offer a fascinating way to see the city.
While making the circuit of the city, you can peer down on the narrow streets below, peek into secret courtyards, and catch a glimpse of day-to-day life.
Walking along the coastal wall, you are also afforded a stunning view of the city and the rugged Croatian coast.
The walk takes about two hours and there is little shade, so take some water and sunscreen.
