Rotterdam – Erasmus Bridge

In the summer and winter, Waterbus Line 20 runs from Dordrecht’s Merwekade to Rotterdam’s Erasmus Bridge. There’s a departure every half hour, and you can travel from Dordrecht to Rotterdam in under an hour. Waterbus Line 20 is a popular route for commuting to and from work. For students, Waterbus is also a pleasant way to start the day. Bring your bike along and grab a quick nap before class or your lecture begins.

There’s plenty of space both inside and outside our boats. You can take a seat inside on our comfortable chairs, or you can choose to sit outside and enjoy the fresh air—a great way to start your day, just the way we like to do it here at Waterbus. Planning a day trip to the UNESCO World Heritage Site of Kinderdijk? Starting October 6, 2025, Line 21 (Rotterdam–Kinderdijk) will be converted into a tourist line:the WaterShuttle. The trip from Rotterdam to Kinderdijk takes about 30 minutes.
