Low Water Levels Force Cancellations & Adjustments to Rhine & Danube Cruises

Travellers on river cruises on the Rhine and the Danube—and the advisors who support them—are finding the going more complicated than usual this month. It’s not the paperwork or the high airfares; it’s a historic heat wave that has the rivers running at levels too low for ships to pass.

“The nature of rivers is to ebb and flow, and this season, lower than average water levels on portions of the Rhine and Danube Rivers have impacted select sailings,” Avalon Waterways told TMR.

While “the vast majority of Avalon cruises continue to operate as planned, Avalon Impression is unable to sail beyond the Koblenz area, and with forecasts showing no sign of improvement, we have made the difficult decision to cancel a small number of upcoming departures.”

This week, Avalon’s Legendary Danube cruise boarded in Passau instead of Nuremberg and had a few port changes that resulted in bus rides, including one from Vienna to Budapest, where the river is not passable, reported Jennifer Hand of Jennifer Hand Travel Pro. Nonetheless, “Avalon has done a great job and we’ve had a lot of fun!”

But as the heat continues and the water evaporates, travel advisors report cancellations and changes to their own or their clients’ cruises across lines and providers.

At Luxury Destinations Concierge, Shantha Mony’s clients on the AmaMagna also were unable to sail into Budapest a few days ago, but nowthe cruise line has adjusted embarkation plans. 

AmaWaterways is providing a hotel stay in Budapest for the first night, and the scheduled Budapest tours the following day. Then guests will be transferred by coach to Vienna, from where the Bratislava excursion will now operate via coach.

“Our clients were very understanding and felt confident that AmaWaterways is doing everything possible to ensure a smooth and enjoyable experience,” Mony said.

Cruise Planners travel advisor Joann Follmann received a letter from Viking noting that “while it is too early to confirm the full impact that water levels will have on your voyage, the current conditions indicate that some modifications will be necessary” on her upcoming cruise on the Danube, such as “adjustments to your docking locations, which could result in longer motor coach transfers for certain excursions.”

“Currently, sections of the Danube and Rhine Rivers are experiencing unusually low water levels,” the company said. “As a result, select Viking river itineraries may be modified. Viking’s nautical and operational teams are closely monitoring conditions and working to minimize any impact to guests’ travel experiences. Guests and their travel advisors are being notified directly by Viking Customer Relations if their itinerary may be affected.”

Viking noted its size and “extensive experience managing variable river conditions in Europe,” the fact that it owns and operates its own fleet of ships, and a Switzerland-based nautical team that “works in coordination with local authorities and port partners to monitor water levels and implement operational adjustments as needed.”

“When river conditions require it, Viking may implement a ship swap, allowing guests and their luggage to transfer to their exact same stateroom on an identical sister ship positioned on the other side of the affected section of river. This approach helps preserve itineraries and reduce disruptions to the guest experience,” the company said.

AmaWaterways, too, has the ship swap down to a science. But it still can be disconcerting to clients, travel advisors note.

At TX Panhandle Luxe Travel Pro, Michelle Osborn’s clients on an AmaWaterways cruise on the Rhine earlier this week switched ships—and therefore missed both scheduled excursions in Basel and only had about 45 minutes in Heidelburg. But now that they are resettled, “things have been much better; the staff, food, and excursions have all been amazing this half of the trip!”

Kristi Zalesky’s clients on a Uniworld cruise on the Danube took a bus to Budapest, where they have spent the past two nights; Sue Colliers’s clients on Tauck will spend the first three days of their trip on a bus before they resume sailing on their original ship on the Rhine itinerary; Cayce Callaway’s clients on Uniworld’s Bucharest to Regensburg itinerary are doing the three-day land part in Bucharest and then being flown to Munich to board in Passau.

Some companies are offering refunds or future cruise credits to clients who choose to sail at a later date.

Avalon is offering the option to travel on a Globus or Cosmos tour, and giving guests until Dec.1, 2026, to make their decision, as “we know a change like this is disappointing, and we want to give our guests time to consider their options rather than rushing them.”

Many cruise lines are not cancelling itineraries.

“Riviera Travel River Cruises are not and will not be cancelling any sailings, but are rather planning different excursions and destinations for guests to travel to,” the company told TMR.  

There have been itinerary changes across seven ships: Riviera Resplendence, Emily Bronte, Oscar Wilde, William Wordsworth on the Rhine; George Elliot on the Mainz; and Geoffrey Chaucer and Riviera Radiance on the Danube.

But guests “are in super high spirits and still very much enjoying themselves,” affectionately describing their holiday as a “Magical Mystery Cruise.”

“I’d say if you’re sailing within the next week to 10 days, there is a very high likelihood you’ll be switching ships and having adjustments to your itinerary,” said Jennifer Elysia at All In Vacations.
