A new river ship is making the case for slow travel on Southeast Asia's most storied waterway. The Viking Tonle, launched in 2025 and named after the Khmer word for "fresh water", is Viking Cruises' purpose-built vessel for the Mekong — and its design tells you everything about the river it serves. At 259 feet long with a flat-bottomed, shallow draft, it's engineered to handle the Mekong's variable water levels and slip into ports bigger boats simply can't reach, gliding along at around 10 miles per hour.
The ship looks like a vintage paddle steamer from outside but is pure Scandinavian inside: floor-to-ceiling windows, light-filled spaces, and a minimalist palette with pops of orange, blue and teal. With just 80 passengers looked after by 58 crew, the service leans heavily towards bygone-era luxury. Accommodation spans three categories: 305-square-foot French Balcony staterooms on the lower and middle decks, twelve Veranda Suites with small step-out terraces, and two 735-square-foot Explorer Suites with separate living areas, a bathtub and wrap-around verandas big enough for loungers. All cabins come with twice-daily servicing, mini-fridges, robes and complimentary movies on demand — plus frosted shower windows that turn clear at the press of a button, ideal for watching the riverbanks drift past.
The real draw is what happens off the boat. Twice-daily excursions, often by sampan — the traditional wooden boats that have worked the Mekong's tributaries for centuries — take guests into rural Vietnam and Cambodia. Highlights include a bicycle rickshaw ride around Sa Dec's riverside lanes and market (deep-fried tarantula, apparently, is on the snack menu), a silk-weaving cooperative in Kampong Cham, and tuk-tuk trips out to taro and tobacco farms. Heavier moments are on the itinerary too, notably Phnom Penh's Tuol Sleng Genocide Museum and the monastery at Oudong, a former royal capital. Arriving into Phnom Penh at sunset, with the golden Royal Palace glowing on the riverbank, is described as the trip's standout sight.
Food is a genuine focus. The kitchen buys fresh produce at every port, and menus change daily, mixing international dishes with regional specialities — think fish amok, Cambodia's national dish, or a banh mi lunch up at the Sky Bar. Drinks with meals are included, with a premium "Silver" package available for those wanting more. Onboard, there's a small spa, a compact plunge pool, a library, and lectures on Mekong life and Cambodian history, plus traditional dance performances from local artists.
This isn't a cruise for anyone after cabaret, bingo and buffet mountains. It's a quiet, culturally engaged experience — waving to passing fishing boats painted with red eyes to ward off evil spirits, watching fish farms twinkle at dusk — and it will suit travellers who'd rather meet a place than be entertained through it.
The full itinerary is the 15-day Magnificent Mekong Cruise, bookended by hotel stays in Ho Chi Minh City and Hanoi, with seven nights aboard the Tonle and three days in Siem Reap to explore the temples of Angkor Wat.
