The Harbour Tour is a cycling tour through the Rotterdam port area, with riders choosing 60, 80, 100, or 140 km. It is designed more as a communal experience ride than a competitive race, and a key attraction is accessing special harbour sites normally off-limits to cyclists.
The routes extend beyond the port to locations such as Zuidland, Vierpolders, and Rockanje. This offers a distinct contrast: industrial docklands, active port roads, and tranquil natural areas within a single day. The event embraces its maritime theme, referring to participants as road captains, helmsmen, and adventurous landlubbers in its unique terminology.
