Viking River Cruise passenger average age is 61 years old. The youngest passengers are two, and the oldest is 84. Most people take their first trip at ages 30-39, but there's no minimum or maximum age to travel.  It is also good to ask for clarification before booking since different cruises have age activities that vary from ship to ship. For example, some ships offer dinner while others do not. Also, some ships may include excursions in which children can take part while others don't. It’s best to check what kind of activity options are included when booking so you know if they fit into your family’s schedule.
