Whouuu... that would be a real Viking raid !
Starting from Norway, sail your way down south to the Straits of Gibraltar, enter the Mediterranean Sea, then sail eastwards along the shores of Spain, then France, until you reach the mouth of the Rhône River - easy to spot : lots of flamingos over here. Then sail northwards, upstream the Rhône, until you reach the confluence of the Rhône and the Saône. There you are !
*OR* sail upstream the Rhine up to its source. Carry the boat across the mountains for a few miles until you reach the source of the Rhône. Then sail gently downstream, across Switzerland and the Geneva Lake, and keep sailing downstream until you reach your target
