UNESCO World Heritage Kinderdijk is the main attraction of Rotterdam.
It's a half-hour ride on Waterbus.
Unlike Zaandijk, Kinderdijk is less commercialized with views on windmills. There are also museums showing how these windmills worked.
Back to Rotterdam, we visited Markthal, an indoor marketplace opened in 2014, with supermarkets, shops, restaurants and small eateries.
Right next to Markthal, is the famous Cube Houses, where it is like walking into a forest in the city.
