Fancy ticking off another country during your holiday to Croatia? This tour takes you across the border to Montenegro for a full-day tour of Kotor, a coastal town that's loaded with cultural and historical sights. You'll skip the traffic and take a ferry to the town where you'll follow your guide during a walking tour of its UNESCO-rated old town. A huge cathedral, ancient city walls, cosy cafes – you'll see them all. There's some free time on the agenda, too, for you to explore on your own. And, if you're feeling adventurous, you can also head up to the hilltop fortress that overlooks the bay – you can walk up, or take a cable car.
