A prolonged drought is setting record low levels on the Danube River and other waterways in the region, the news source said. In a recent social media update, Riviera Travel said that its teams continue to monitor river conditions and potential impacts on its operations. “We know that news about changing river conditions may raise questions when you’re looking forward to a much-anticipated holiday. That’s why we wanted to reassure you about how we’re looking after your travel plans,” the company stated. In late July, the Viking Ullur had to be evacuated after running aground on the Danube River with over 185 passengers and 50 crew members.
