The ferries run year-round from Arsta Havsbad Pier and during the summer months even from Stromkajen in downtown Stockholm. If you are taking the ferry from Arsta Pier and have your own car take Highway 73 towards Nynashamn taking the exit marked Forsvarsmakten Berga- Arsta Havsbad and follow the signs to Arsta Brygga. Once at Arsta Pier there is parking for about 50 SEK per day payable by credit card at the ticket machines located in the lots. The trip takes approximately 30 minutes from central Stockholm when traffic is running smoothly.
If you are travelling with public transportation take the shuttle train, pendeltag, from T-Centralen to Vasterhaninge changing there to Bus #846 which will take you all the way to Arsta Pier.
