Slip on your sensible footwear and spend two hours following your guide through the cobbled streets and narrow alleys of Kotor, alive with local color. The city of Kotor, nestled on a narrow strip of coast at the foot of Mount Lovcen, was at the height of its development in the Middle Ages. It was during this time that its stone fortification walls were built; they are still in existence today. This UNESCO World Heritage Site boasts the centuries-old St. Tryphon Cathedral, built in 1166. Pause here to admire its Romanesque and Byzantine architecture before stepping inside to take in its stunning interior with jewel-tone frescos and a gilded altar. Continue your stroll to the Maritime Museum, where you'll uncover the city's naval history. This concludes the guided portion of your tour, but now that you are well-oriented, you can take some time to explore independently. Enjoy ample shopping and quaint cafes before returning to port at the conclusion of this charming day.
