Travelling in Amsterdam by public transport is straight-forward and convenient. On the many trams and busses of Amsterdam, you can buy one-hour tickets. When you’re crisscrossing through the city for more than one day, this can be a bit expensive. In this case we advise you to buy the public transport chip card (in Dutch: OV-chip card), which you can buy and upload at the Central Station and in most tobacco stores.
