Fascinating Vietnam, Cambodia & the Mekong River (Northbound)

Vilshofen an der Donau is a handsome Bavarian river town where three streams converge with the Danube, its medieval market charter and Gothic Stadtturm bearing witness to eight centuries of river trade prosperity — though its most joyful claim to fame is the boisterous Vilshofen Volksfest, Bavaria's second-largest folk festival after Oktoberfest, held each June. The pastel-painted baroque townhouses and arcaded courtyards of the compact old town make for an idyllic Danube-side stroll, while the surrounding farmland and rolling hills of Lower Bavaria offer cycling routes of pastoral serenity. Summer brings the festival season; spring and autumn lend the Danube Valley its most golden and peaceful character.

Passau occupies one of Central Europe's most dramatic natural stages — a narrow peninsula at the confluence of three rivers, the Danube, Inn, and Ilz, where the old town's baroque spires and shuttered merchants' houses crowd the very tip of the land between the waters. St. Stephen's Cathedral houses the world's largest church organ, a 17,974-pipe instrument whose daily concerts fill the nave with a sound that seems architectural in its density. The Veste Oberhaus fortress above the city commands panoramic views across three countries on clear days. Passau is a classic Danube river cruise departure point; spring and early autumn, when the river runs high and the light turns golden, are the finest seasons.

Austria's third city has accomplished one of Europe's most convincing urban transformations — reinventing itself from industrial centre to cultural powerhouse, a journey recognised in 2009 when it was named European Capital of Culture. The Ars Electronica Center, a museum of digital art and technology that glows with LED light across the Danube each evening, epitomises Linz's forward-looking identity. Yet the city's Roman roots, its baroque Hauptplatz (one of Austria's finest main squares), and its proximity to the Wachau Valley anchor it firmly in history. The Upper Austrian cuisine — particularly Linzer Torte, the world's oldest-documented cake recipe — is exceptional. Linz is most agreeable May through September.

Melk Abbey is among the most theatrical expressions of Baroque ambition in all of Europe — a gilded monastery perched on a granite outcrop above the Danube, its domed church and frescoed library presiding over the Wachau Valley with serene authority since Benedictine monks replaced the Babenberg fortress in 1089. Umberto Eco immortalised it as the inspiration for his labyrinthine monastery in "The Name of the Rose," and the library's 100,000 medieval manuscripts remain one of the continent's supreme collections. After the abbey, stroll down to the historic market town and sample the valley's celebrated Grüner Veltliner wines. The Wachau is at its most bewitching in April and October.

Vinh Long is a river town at the heart of Vietnam's Mekong Delta, renowned for its bustling Cai Be floating market, lush fruit orchards on river islands, and the delta's distinctive cuisine. Must-dos include a dawn sampan visit to the floating market, tasting crispy elephant ear fish wrapped in rice paper, and visiting island orchards and coconut candy workshops. November through April's dry season offers the best weather for delta exploration.

The port of Vienna is a cultural gem along the Danube River, famous for its stunning architecture, rich history, and vibrant culinary scene. Must-do experiences include sampling authentic Wiener Schnitzel and visiting the picturesque village of Dürnstein. The best season to visit is spring or early fall, when the city's gardens bloom and outdoor activities abound.

Châu Đốc is a mystical border town where the Mekong meets Cambodia, combining Vietnamese, Cham Muslim, and Khmer Buddhist cultures around the pilgrimage mountain of Sam (Núi Sam). Must-do experiences include visiting Sam Mountain's pagodas, touring floating fish farms, and tasting the town's famous bún cá turmeric fish noodle soup. November through April's dry season is most comfortable; the flood season reveals the delta's full hydraulic drama.

Long Khánh is southern Vietnam's tropical fruit capital, set in volcanic red-earth highlands known for durian, rambutan, and mangosteen orchards. Essential experiences include visiting pick-your-own fruit farms, tasting bún riêu noodle soup, and excursions to Cát Tiên National Park's ancient forests. May through August is peak fruit season for the most spectacular tastings.

Bratislava, the only national capital bordering two sovereign states, sits sixty kilometres downstream from Vienna on the Danube — close enough for a day trip to the Austrian capital, yet possessed of its own entirely distinct character: a pastel-hued medieval old town of hidden courtyards, playful bronze statues, and hilltop castle views, where wine bars pour outstanding Slovak Riesling at prices that make the Viennese feel extravagant. The city's dramatic reinvention since 1989 has produced a dynamic, youthful culture that fills the old quarter's restaurants and concert halls with genuine warmth. Pair with Vienna or Budapest for the classic Danube river trilogy; all three cities are within two hours of each other.

Esztergom, Hungary's former royal capital and birthplace of King Saint Stephen, commands the Danube Bend with the nation's largest basilica crowning its ancient Castle Hill. Visitors should not miss the cathedral's panoramic cupola and a bowl of authentic halászlé by the riverside. The city is at its most luminous from late April through October, when golden light transforms the neoclassical architecture and the Danube sparkles beneath the hilltop silhouette.
