The north lies fairly isolated from the rest of Amsterdam, but luckily, there is a free GVB ferry from Central Station in the Old Center. Instead of just being a way to get in, the ferry ride is an attraction in itself. It gives a great view over the urban harbor-front, and shows the diversity of the north's residents. Large signs show when the next boat is departing, and when it does, expect masses of locals getting on with their bicycles. Getting on just before the boat leaves seems to have turned into a sport here. You can take off at different piers, the NDSM shipyard being the most notable. If you want to do some further exploring, be sure to bring a bicycle and a decent map.
