The Bay of Kotor is not technically a fjord — the geologists insist it is a submerged river canyon — but it does the work of one. Mountains drop straight into water; medieval towns cling to the shore like barnacles; the light, at certain hours, makes the whole basin look painted.
Kotor itself is the jewel. A walled old town, UNESCO-listed, Venetian in bones and Slavic in soul. You enter through the Sea Gate and immediately lose your sense of direction in a maze of marble squares, churches, and palaces compressed into a few hundred meters.
The cruise ships arrive most mornings in summer, and for a few hours the town belongs to them. Then they leave, and Kotor returns to itself: locals walking dogs through the squares, kids playing football against church walls, swallows looping above the rooftops.
The fortress walls climb 1,200 steps. Do it at dawn, or do not do it.
The hike to the Castle of San Giovanni is the city's signature challenge — 1,350 steps up the cliff behind the town, with views down onto the bay that justify every breath. Go at five-thirty in the morning, with a headlamp and a bottle of water. By the time the sun lifts over the mountains, you will have the fortress to yourself.
Kayak the bay in the afternoon. Paddle to the church of Our Lady of the Rocks, a tiny island built by fishermen over five centuries. Eat at Galion outside the walls for grilled sea bass and a view across the water to Perast.
Stay at Palazzo Drusko inside the walls — a 14th-century palace with thick stone rooms and breakfast in the courtyard. Compared to Croatia just across the border, prices in Montenegro remain reasonable. Go now. In ten years, this will be a different story.
