Montenegro, set along the Adriatic Sea, draws travelers with its dramatic landscapes and layered history. The Bay of Kotor, often mistaken for a fjord, is actually a submerged river canyon surrounded by steep cliffs and medieval towns. Kotor itself, a UNESCO World Heritage site, is enclosed by ancient fortifications that visitors can climb for panoramic views stretching from terracotta rooftops to the sea.

Barranquilla sits near the mouth of the Magdalena River on Columbia's Caribbean side. It is a major seaport and a center of commerce, but everyone breaks loose for four days in February for one of the liveliest carnivals outside of Rio.

Carcassonne is a fortified city in southern France, rising above the Aude River with walls and towers that feel lifted from another century. Its origins stretch back to Roman times, but the city is best known for its medieval citadel, rebuilt and expanded during the Middle Ages when Carcassonne became a strategic stronghold on key trade and military routes.

On Greenland’s west coast, Ilulissat (once known as Jakobshavn) welcomes travelers with astonishing ice scenery and a sense of scale that feels almost otherworldly. The town sits beside Disko Bay, where immense icebergs drift silently past, glowing pink and gold in the Arctic light. The name “Ilulissat” means “icebergs,” and it could not be more fitting. Here, every turn toward the sea offers a fresh view of towering ice forms, each one sculpted by nature into something fleeting and beautiful.

Luxembourg City, the capital of the Grand Duchy of Luxembourg, is a stunning blend of medieval charm and modern sophistication.

The UNESCO-listed Old Town is an essential starting point for visitors, with its ancient fortifications, narrow cobblestone streets, and grand squares.
