Boat excursion from Rotterdam to Kinderdijk and back. Leaves daily (05/04 – 05/10) from the centre of Rotterdam with one of our luxury passenger ships, where service and customer friendliness come first. Sailing over the Nieuwe Maas and the Lek Rivers, guided tours in several languages will inform you of all the sights you are passing. After about a 1-hour sail, the ship ties up at Kinderdijk, a historical location known for its 19 traditional windmills, which is now a United Nations global cultural monument. The passengers have 60 minutes to visit one of the windmills. After this interesting and educational hour, you sail back to Rotterdam.
