As well as opening bookings for 2025, Viking has added a new Paris and D-Day 80th Anniversary cruisetour to its 2024 European river season.
With departure dates running from March through to November 2024, the 12-day itinerary from London to Paris will commemorate Operation Overlord and the battles of Normandy.
Guests will begin their journey with four days in London to visit historic World War II sites before continuing on to Paris to embark on a Viking Longship.
Wendy Atkin-Smith, managing director of Viking UK, said: "The start of 2023 has been incredibly busy and successful for us – so much so that our European river sailings and other itineraries including the Nile are almost fully booked this year."
