Top wine regions for river lovers

From Ancient Lakes to Zamora, there are countless regions where you can explore both wine and riversides to your heart's content. If your taste leans towards the New World, follow the Columbia River as it traverses the Pacific northwest, through Washington and Oregon states. If Europe is more your thing, the Duoro is a natural guide to the many varied wine regions of northern Iberia or go truly multinational, and follow the Danube's path through Austria, Croatia and Serbia.
