Europe’s prolonged drought and record summer heat are forcing river cruise operators to rethink itineraries, with low water levels affecting sections of the Rhine and Danube and prompting a range of contingency measures to keep holidays on track.
While some itineraries have been adjusted, major river cruise brands say cancellations remain rare as they deploy ship swaps, revised embarkation points and alternative transport to minimise disruption for guests.
According to reports, water levels on parts of the Danube have fallen to their lowest point in three decades, with sections of both the Danube and Rhine experiencing navigation restrictions and, in some areas, temporary lock closures.
River cruise operators have long dealt with fluctuating water levels, but the combination of prolonged drought and heatwaves has increased the frequency of operational changes during the peak European summer season.
Riviera Travel reported it had no plans to cancel sailings, instead adapting shore excursions and, where necessary, substituting destinations to maintain the guest experience. The company said some travellers have affectionately referred to their flexible itineraries as “Magical Mystery Cruises”.
Contingency plans
Scenic Group, Australian parent company of the Switzerland-based Scenic Luxury Cruises & Tours and Emerald Cruises, confirmed that low water levels between Regensburg and Passau in Germany have impacted parts of the Danube. Privately owned by Australian businessman Glen Moroney and his wife, Karen Moroney, the company is using ship swaps and modified embarkation and disembarkation ports to continue operating affected itineraries.
Amawaterways said despite current low water conditions it assured travellers cruises are still operating.
“Because river conditions can change rapidly, our teams continually assess the situation and communicate directly with affected guests whenever updates are needed,” it said in a statement to guests. “Our Operations team closely monitors river conditions every day and works with our nautical team, onboard crews and local partners to make any adjustments needed while maintaining the highest possible guest experience.”
Tauck has also adjusted a limited number of Rhine and Danube departures, drawing on contingency plans developed over more than two decades of operating European river cruises.
The company said its response includes transfers between sister ships, alternative transport, revised boarding points and hotel stays designed to preserve the overall itinerary with as little disruption as possible.
“Tauck has successfully navigated low-water conditions many times over our 20+ years on Europe’s rivers, and thankfully we have tried-and-tested contingency plans in place,” the operator said in a statement.
Viking, which operates one of Europe’s largest river cruise fleets, is also relying on its network of sister ships to transfer guests around affected sections of the rivers while maintaining cabin assignments and onboard experiences.
“This approach helps preserve itineraries and reduce disruptions to the guest experience,” it said in a statement.
Despite the challenges, travel advisors say communication from operators has been strong. Importantly, only certain stretches of the Rhine and Danube are currently affected, with most of the waterways remaining navigable.
The situation is also reinforcing a growing trend towards shoulder-season departures, with many travellers increasingly opting to cruise in spring, autumn and during the popular European Christmas markets, avoiding the hotter and less predictable conditions of mid-summer.

Nothing new
Low water levels are not new to Europe’s river cruise sector. The Danube and Rhine have experienced several significant drought events over the past decade, including in 2018, 2022 and 2025, when exceptionally dry summers disrupted navigation and forced operators to alter itineraries.
River cruise companies have since refined their contingency plans, investing in flexible logistics, sister-ship networks and alternative land transport to ensure guests can continue their journeys with minimal disruption.
The recurring events have also highlighted the growing impact of climate variability on European inland waterways and the importance of operational flexibility for cruise operators.
