1. Kotor Bay, Montenegro
In Montenegro, the Adriatic Sea slaloms through narrow passages in the steep Dinaric Alps to form the Bay of Kotor. Here, squeezed between water and rock is the triangular, medieval Old Town of Kotor, with its gravity-defying fortress zigzagging up the steep cliffs above. Although it’s possible to climb the fortress steps from town, I prefer to wander the winding shepherd’s trail on the fortress’ northern flank. It’s here, amid the ruins of a deserted, roadless village, that you can munch on homemade sheep’s cheese and rye bread at the last inhabited farmhouse, overlooking the bay’s glassy, obsidian water.
