Low Water Still Disrupts European River Cruises Despite Rain
Viking says it can place identical sister ships on opposite sides of an impassable river section, letting guests cross by road into the same stateroom layout.
Rain across France, Germany and Central Europe has eased some navigation restrictions on the upper Danube, but Emerald Cruises, Saga River Cruises and Viking are still preparing itinerary changes as low water persists across European rivers. Emerald has substituted Emerald Destiny for Emerald Sky on its Aug. 30, 2026, seven-night sailing from Budapest, while Saga and Viking continue to assess departures individually.
The European Drought Observatory assessed conditions as critical across most of Europe in early August, and operators are still contending with shallow sections of the Danube, Rhine and Main after a prolonged drought and heat waves.
Emerald changes ships as Budapest section stays uncertain
Emerald expects the portion of its itinerary from Bratislava to Regensburg to operate as scheduled. Conditions between Budapest and Bratislava are less certain, however, and the line is monitoring whether that section will reopen to navigation before embarkation.
Guests will travel aboard Emerald Destiny as a precaution. The replacement is similar in size to the 135-meter, 3,544-gt Emerald Sky, built in 2014, and both vessels carry up to 182 passengers. Emerald plans to provide further operational details closer to departure.
Recent operator alerts have identified several pressure points on the Danube, including stretches between Regensburg and Passau, around Dürnstein and Melk, and between Vienna and Budapest. On the Rhine and Main, affected areas have included the route between Koblenz and Rüdesheim and sections near Maxau.
Saga and Viking use different contingency plans
Saga said in an Aug. 18 update that it was adjusting operations cruise by cruise. Its alternatives include routes through the Dutch waterways, the Main and navigable sections of the Danube, with existing flights retained where possible to limit lengthy ground transfers.
“We won't turn your itinerary into a coach holiday; the ship will be sailing,” Saga said. Affected guests will be contacted directly.
Viking’s Aug. 20 update said some Rhine and Danube itineraries could still require changes. The company contacts affected passengers and travel advisors before departure and can place identical sister ships on opposite sides of an impassable river section.
Under that arrangement, passengers leave one vessel, cross the closed section by road and join its sister ship. Viking says matching layouts allow guests to move into the same stateroom on the replacement. Its fleet exceeded 70 river vessels by 2026 and includes standardized 135-meter Longships generally carrying 190 passengers.
How other lines are coping
Other operators have reported a mix of cancellations and modified operations. Avalon Waterways canceled selected departures of its Danube Dreams itinerary, while Uniworld reassigned ships on several August cruises. AmaWaterways said it had not canceled a departure because of the summer’s low-water conditions, relying on altered routes, transfers and sister ships where needed.
“We don't wait until conditions become a problem,” Jon Burrows, chief operations officer of AmaWaterways, said. He said teams monitor forecasts, navigation information, hydrological data and updates from ports and ship crews while evaluating contingency plans.
On a Uniworld sailing aboard S.S. Emilie, the vessel could not continue beyond Vilshofen and missed calls at Deggendorf, Regensburg and Nuremberg. Some excursions were operated by bus, while passengers with flights from Nuremberg left the ship a day early and stayed in a hotel before airport transfers the following morning.
Viking Ullur, a 443-foot river ship built in 2019, grounded near Vidin, Bulgaria, on July 28 with 186 passengers and 52 crew aboard. Authorities cited low water and nighttime conditions and said the vessel had moved outside the navigable channel before grounding. No injuries were reported, and passengers were evacuated during daylight before continuing to Bucharest.
Water levels can change quickly following rainfall, leaving operators reluctant to finalize adjustments far in advance. Uniworld said it was too early to determine whether its September and October departures would require changes.
AmaWaterways expects to complete sister-ship deployment across both the Rhine and Danube by 2028 following the additions of AmaRudi and AmaFiora.
