Staying or living nearby? Cycling is most certainly the best and quickest option for you. Follow the bicycle signs to the festival, and park your bicycle in the designated areas.
At Hoofddorp Station, you can borrow an OV-bike which you can rent for only €3,85 for 24h. After the festival, simply return it at the station. Super convenient, but make sure you are on time – there is only a limited number of bikes available!
