Danube Symphony with 1 Night in Budapest (Westbound)

Paris rewards every arrival as though it were the first — the sweep of the Seine, the Gothic tracery of Notre-Dame rising again from its 2019 ashes, the Eiffel Tower somehow managing to astonish at each encounter, the Louvre's glass pyramid reflecting clouds in the courtyard of a palace that served French kings for four centuries. Beyond the monuments, Paris is a city of neighbourhoods: the Belle Époque brasseries of Montparnasse, the covered passages of the 2nd arrondissement, the rooftop terraces of Le Marais. The Luxembourg Gardens in April, or a late-September evening on the Canal Saint-Martin, are among the most civilised experiences in the world.

Bordeaux, France's premier port city, is renowned for its historical significance, stunning architecture, and world-class wine. Must-do experiences include savoring local delicacies at Marché des Quais and exploring the breathtaking art installations at Place de la Bourse. The best season to visit is during the late spring and early autumn, when the weather is pleasant and the vineyards are in full bloom.

Cadillac, a picturesque commune in the Gironde department, is celebrated for its rich history, charming architecture, and exquisite culinary offerings. Must-do experiences include savoring local delicacies like foie gras and exploring the historical Château de Cadillac. The best season to visit is during the spring and early autumn, when the weather is delightful, and local markets are bustling with fresh produce.

Where the Gironde estuary broadens toward the Atlantic, Cussac-Fort-Médoc occupies a quietly magnificent corner of Bordeaux wine country, its landscape shaped by Vauban's seventeenth-century star-shaped citadel — a UNESCO World Heritage fortification — and by centuries of châteaux producing some of the Left Bank's most distinguished Haut-Médoc cuvées. River cruisers dock here for château visits and private cellar tastings amid working vineyards, far from the tourist circuits of Saint-Émilion. September brings the harvest, filling the air with the intoxicating scent of fermenting Cabernet Sauvignon; the temperate maritime climate makes spring and autumn equally rewarding.

Krems an der Donau has stood at the eastern gateway of the Wachau Valley — Austria's most beautiful stretch of the Danube — since Emperor Otto III granted it market rights in 995 AD, making it one of the country's oldest documented towns. The UNESCO-listed Wachau landscape surrounding the city is a masterpiece of vineyard terraces, Baroque abbeys, and medieval castles reflected in the river; the Grüner Veltliner and Riesling wines produced here are among Austria's finest. Must-dos include visiting the monumental Melk Abbey and cycling the Danube Cycle Path through the valley. Krems is most enchanting April through October, with the harvest season in September offering wine cellar tastings of exceptional depth.

Neuhofen an der Ybbs is a charming port town in Lower Austria, steeped in history and offering a unique blend of serene riverfront views and traditional architecture. Must-do experiences include sampling local specialties like Wiener Schnitzel and attending the weekly farmer's market. The best season to visit is during the spring and summer months when local festivals and outdoor activities bring the town to life.

Crowned by a Vauban citadel that UNESCO recognises as one of Europe's finest military fortifications, Blaye guards the Gironde estuary with a watchful grandeur unchanged since Louis XIV's engineers completed their work in 1689. Taste the local delicacy of poutargue de Blaye — cured mullet roe from the estuary — explore the merlot vineyards of the Blaye Côtes de Bordeaux appellation, and take an excursion south to Bordeaux's grand neoclassical boulevards. September and October bring the heady aromas of harvest season to the surrounding wine country.
