Treasures of the Rhine, which will debut in December 2023, will see Viking offer departures throughout January, February and March.
The 10-day sailing will take guests to a Unesco World Heritage site, and visit cathedrals and medieval towns onboard a 190-guest Viking longship.
"The Middle Rhine is one of our most popular destinations – with constantly changing views of hilltop castles, historic towns and terraced vineyards along the steep valley sides, it is a region that will always be best explored by the river," said Torstein Hagen, chair of Viking.
