The Kiel Canal, located in Kiel, is the longest and busiest artificial canal in the world. It stretches 100 kilometers from the Baltic to the North Sea. The canal can be cycled in its entirety or as part of a day excursion; the bike route runs alongside the water, providing an up-close encounter with massive container ships. The route is well-suited for bicyclists, with plenty of lodging options, points of interest, and eating establishments along the way.
