In Ybbs an der Donau, two completely different bodies of water meet. While the mighty, navigable Danube dominates the cityscape to the north, the much wilder and more natural Ybbs flows into the river here. You can often see a difference in color in the water. The Ybbs brings cool, clear mountain water from the Eisenwurzen, while the Danube usually has a more greenish-gray color.
