We pre-booked this trip with TripAdvisor and met the crew by the boat almost next to the Magere Brug. They welcomed us on board with a safety brief and off we went. The trip took us peacefully meandering through a maze of canals, stopping at Anne Frank's House to collect some more passengers and we were given 10 minutes to hop off and take some pictures. Drinks are included in the trip, although this is not self-service but the crew are very good at keeping you topped up. The guide had very good English and pointed out a reasonable number of sights as we were touring, although this could perhaps have been a bit more detailed.
The boat does not have a roof and so if it does start to rain you will get wet! We sat at the front of the boat and enjoyed the comfy cushions. There is also a toilet on board (no.1 only!!). The tour lasts 75 minutes and drops you off at the same spot you board at.
Lovely way to see the city and great value.
