One of the best parts of cruising to Kotor is getting there. The Bay of Kotor, oft referred to as a fjord (although it's not), surrounds you with towering mountains all the way to the Old City. Once you set foot on its stone streets, you can gallivant past churches, squares and other buildings dating back to the Middle Ages -- or soak up the view from above, with a 90-minute hike up to the fortress.

Colorful Colonial-style buildings, alfresco cafes and lively little plazas are steps away, making it easy to make the most of a few hours' visit.
