Romantic Rhine with 2 Nights in Lucerne (Northbound)

Phnom Penh rises from the confluence of the Mekong, Tonlé Sap, and Bassac rivers with a resilience that makes it one of Southeast Asia's most affecting capitals — a city that endured the Khmer Rouge's "Year Zero" and has re-emerged as a place of broad riverfront boulevards, excellent Khmer cuisine, and a cultural energy that feels earned rather than manufactured. The Royal Palace and its Silver Pagoda, housing a life-size gold Buddha studded with 9,584 diamonds, is the city's architectural centrepiece; the Tuol Sleng Genocide Museum, a former high school converted to a prison by the Khmer Rouge, is sobering but essential history. November through February offers the most comfortable climate for extended exploration.

Angkor Ban is a riverside Mekong village in Cambodia's Kampong Cham Province where unvarnished authenticity awaits the discerning river cruise traveler — a world away from tourist infrastructure, offering a rare glimpse into rural Khmer life unchanged by modernity. Ancient laterite temple ruins hide among the trees, while local craftspeople practice traditional silk weaving and pottery in family compounds that welcome visitors with quiet warmth. The dry season from November through April offers the most comfortable conditions for exploring the village lanes and surrounding countryside on foot or by bicycle. Phnom Penh is a half-day's river journey downstream.

Framed by snowcapped Alps and the mirror-bright waters of Lake Lucerne, this medieval Swiss gem centres on the 14th-century Kapellbrücke — one of Europe's oldest covered bridges — and a colourful Altstadt that has changed little in five centuries. Ride the cog railway to cloud-wreathed Mount Pilatus, savour Älplermagronen in a timber-beamed tavern, and explore the nearby wonders of Interlaken and Grindelwald. Late spring through early autumn offers the most spectacular lake reflections and settled mountain weather.

Kampong Tralach, Cambodia is a distinctive port city where deep cultural heritage meets authentic local atmosphere, featured on itineraries by AmaWaterways. Must-do experiences include exploring the vibrant local markets for regional specialties and fresh seafood, and discovering the waterfront quarter where maritime heritage meets contemporary energy. The optimal time to visit is November through April, when dry season brings clear skies and calm seas.

Basel, where Switzerland, France, and Germany converge at the Rhine's northward bend, hosts a concentration of world-class art institutions that rivals any city its size on earth — the Kunstmuseum alone, the world's oldest public art collection, could occupy days, and Art Basel each June draws every name that matters in the contemporary art world to this compact, elegant city. The Rhine itself is the city's great social artery: in summer, locals jump in with waterproof bags and float downstream, a tradition as charming as any museum. Spring through autumn is ideal for outdoor exploration; Paris is just three hours by TGV and Strasbourg a mere twenty minutes by train.

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.

Rüdesheim am Rhein, a jewel of the UNESCO-listed Upper Middle Rhine Valley, is where Germany's most storied wine river cuts through vine-terraced slopes and medieval castle ruins. The pedestrianised Drosselgasse laneway — beloved since the Romantic era — hums with wine taverns pouring the region's celebrated Rieslings, crisp and mineral from the slate soils. The Niederwald Monument surveys the river from the heights, reached by cable car above the vineyards. Day trips by boat unlock Bacharach, Boppard, and the legendary Lorelei rock. September's harvest festivals transform the entire valley into a convivial celebration of the vintage.

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.

Koblenz stands at the Deutsches Eck — the German Corner — where the Moselle river pours into the Rhine in a confluence so geographically commanding that the Romans built a fortress here in 9 BC. The result is a city of exceptional Rhine Gorge scenery, with the formidable Ehrenbreitstein Fortress, one of Europe's largest, crowning the opposite bank and reachable by gondola for panoramas that stretch across three river valleys. A Rhine wine tasting at one of the city's historic Weinstuben, followed by a stroll through the Altstadt's baroque squares, is the definitive Koblenz afternoon. The finest weather arrives April through October, with the Rhine in Flames fireworks festival in August being particularly spectacular.

Still whispered as Saigon by its ten million residents, Ho Chi Minh City pulses with an energy that outlasted every empire and every war. The French colonial grandeur of Notre-Dame Cathedral and Gustave Eiffel's Central Post Office stands in vivid counterpoint to the city's kinetic street life — an endless river of motorbikes, fragrant with pho broth and charcoal-grilled meats. Do not miss the Reunification Palace, a time capsule of Cold War modernism, or a dawn bowl of bánh mì from a sidewalk vendor. The dry season, November through April, offers the most comfortable conditions for exploration.
