The NDSM-veer is one of the 3 free ferry connections, that shuttles between Amsterdam Central Station and the NDSM-werf.
This is also the ferry to use to get to the Amsterdam Marina and the urban beach Pllek.
The ferry is free to use, and you can bring your bike or moped.
Please note: it does not go during the night (after midnight you must use the Buiksloterweg Ferry).
On Friday and Saturday nights (between midnight and 3am) you can use the Nachtelijk Westveer, which connects NDSM with Central Station.
