From Den Helder station, take bus line 33 to the boat. This bus leaves 12 minutes past every hour and is coordinated exactly with the schedule of the boat. You will be dropped off at the ticket counter for the TESO ferry. You can then board the boat after you buy a round trip ticket. Want to continue with a bus when you reach Texel? Then leave the boat on the right-hand side. Travelers for Den Burg and De Koog can take bus line 28. If you have another destination, then you can take a Texelhopper mini-bus. These buses have to be reserved in advance (www.texelhopper.nl).
Attention: The OV-chip card is not valid on Texel. In order to cross over with the ferry, you have to buy a separate ticket at the TESO ferry ticket counter in Den Helder.
