naturum Kosterhavet, Kosterhavets nationalpark

To get to the main entrance of the national park on Sydkoster, you can take one of Västtrafik's Koster boats that depart from Strömstad. The journey takes about 45 minutes. On the way you pass through beautiful archipelago areas and over the deep channel of Kosterfjord.

The main entrance is in the National Park's information center - naturum - located at Ekenäs on South Koster. Here you will find knowledgeable staff and an exhibition that tells about the nature of the Koster Sea.
