Europe's river cruise season has been upended by drought. Water levels on the Danube near Budapest were close to record lows in August, and Romania saw its lowest levels since 1996. The Rhine isn't faring much better, and with little rain since, rivers have yet to recover — making it hard for ships to dock or even sail certain stretches.
The practical fallout is real. Tui River Cruises passengers recently complained about being bussed between destinations and put up in hotels instead of cruising the Danube. Riviera Travel has cancelled three October Danube departures outright and revised nine Rhine sailings, with chief guest experience officer James Golding calling 2026 an unprecedented year for low water. On the Rhine, rather than calling at Rüdesheim, Speyer, Strasbourg and Breisach, some ships have been rerouted onto the Moselle, stopping at Cochem, Bernkastel, Trier and Koblenz instead.
Cruise lines have a playbook for this. Viking and Riviera position identical sister ships on opposite ends of the same route, so if a stretch becomes unnavigable, guests simply walk across to the twin ship — same cabin, same itinerary. On one June Viking Rhine Getaway from Amsterdam to Basel, guests moored in Koblenz for 24 hours, then took a five-hour coach ride to Strasbourg to board the second ship. AmaWaterways says ship deployment is planned two years ahead, so spare vessels are usually available, and extras like coach transfers and hotel nights aren't passed on to guests.
If your sailing is cancelled entirely, you'd typically get a refund or rebooking credit. Itinerary changes mid-cruise, though, usually fall under the booking's terms and conditions — meaning no automatic compensation. Insurance experts recommend a dedicated cruise insurance policy: unlike standard travel cover, some plans explicitly cover insufficient (or excessive) water levels, plus prepaid excursions you miss or connecting flights disrupted by the shuffle.
Operators stress this is still the exception rather than the rule, and disruption elsewhere in Europe has been minimal — Uniworld says its sailings in France, Italy and Portugal are running as scheduled. But with hotter summers becoming routine, lines are building in more flexibility; Riviera has launched a Holiday Guarantee offering clear choices, rebooking or refunds when itineraries change significantly. Travellers wanting to sidestep the issue altogether might consider rivers less affected by this year's drought — the Seine, Douro, Mekong and Nile have all sailed normally, and industry body CLIA notes growing interest in long-haul river cruising beyond Europe altogether.
If you've booked a European river cruise for the coming months, stay in close contact with your operator or agent, read the itinerary-change terms before you travel, and check whether your insurance includes cruise-specific cover. Flexibility is the name of the game this season.
