The moving attractionVilkynė is the only motor ferry across the Nemunas in Lithuania.
It carries pedestrians, bikes and cars seasonally, usually from May to November. That is not merely transport. Put the car on a boat once and an ordinary road trip suddenly remembers it is beside a river.
And then Louis Armstrong enters the story.
Near the waterfront is an Armstrong square, created in memory of the musician and his adoptive parents, who came from Vilkija. Add the Juška ethnographic museum, Jewish heritage traces and the viewpoint, and the little town has far more narrative density than its size suggests.
The ferry timetable is allowed to defeat your plan. A seasonal boat is not late; your spreadsheet was overconfident.
