On the west coast of Sweden, on the border to Norway, the first marine national park in Sweden is established. It is easy to get to the various parts of Kosterhavet National Park. Take the train along the Bohusbanan line or the bus from Gothenburg or follow E6 north towards Strömstad by car. If you are coming from Oslo (Norway), follow E6 towards Strömstad.
Kosterbåtarna/the Koster Boats depart year-round from Strömstad. The trip takes about 45 minutes. En route you pass through beautiful archipelago areas and cross the Koster fjord’s deep trench. Resö, Rossö, Tjärnö and Saltö also afford excellent views of Kosterhavet, and there are road connections to them.
At Västtrafik you can find information yourself on connections and timetables to the Koster islands, Resö, Rossö, Strömstad, Tjärnö/Saltö and other places.
