Kotor
The UNESCO-listed walled old town sits at the deepest point of the bay — a Venetian quarter tucked beneath Mount Lovćen, with the fortress walls climbing 1,200 steps up the cliff behind it for the postcard view. The waterfront is now closed to non-resident cars during peak hours, which has cut local emissions sharply. Stay inside the walls in a converted palazzo, or in Perast 12 km up the bay for the Our Lady of the Rocks islet views.
