Fodor's Expert Review Gradske Zidine

Especially beautiful at night when illuminated, Kotor's well-preserved town walls were built between the 9th and 18th centuries. They measure almost 5 km (3 miles) in length and reach up to 66 feet in height and 52 feet in width. They form a triangular defense system around the Old Town, then rise into the hill behind it to Tvrđava Svetog Ivana (St. John's Fortress), 853 feet above sea level. You can walk up to the fortress along the walls; allow at least one hour to get up and back down, wear good hiking shoes, and remember to bring water.
