There are plenty of parking places in around the old Zuiderpark Stadium.
However, as this stadium is now only used for training sessions, the best way and the easiest way to the stadium is by using public transport.
Take tram 9 from Centraal Station or Station Hollands Spoor / Stationsplein, direction Vrederust. It is approximately 10 minutes from Centraal Station and 5 minutes from Hollands spoor.
There are two tram stops, firstly Moerweg, then Zuiderpark/Melis Stokelaan, which is the closest to the stadium. From Melis Stokelaan walk into the park and keep to your right hand side, this will take you directly to the stadium in 5 minutes.
