Rotterdam is showing off its best side this Tuesday evening. Clear sea air, clouds passing across the sky, now and then the sun peeps out behind them. The city in the east of the Netherlands stands for an eventful history, strong contrasts, the attached port – one of the largest in the world – and is also called "Manhattan on the Meuse" because of its exciting skyline. One could accuse Rotterdam of a certain coolness – which, however, considering its inhabitants, leads you completely down the wrong track. Exploring the city, getting to know its hidden corners and making new friends in the process: this is exactly what Ido set out to do years ago. At irregular intervals since then, he has been organising so-called city walks, which are not intended for tourists but for locals, and which also more so constitute hikes with added value. Together they experience the transit zone between city and countryside.
