Welcome to Sweden’s first marine national park.
Visit Sweden’s one and only marine national park. The National Park lies off the coast in northern Bohuslän and stretches from the town of Strömstad in the north to Grebbestad in the south. These are the most species-rich waters in Sweden.
The national park’s main information centre – “naturum” – in Ekenäs on South Koster, offers expert help. Check out the interactive presentations and films about Kosterhavet and don’t miss the aquarium where you get to see and touch various species.
A nature reserve is created to preserve habitats, flora or fauna, which gives you the opportunity to experience untouched archipelago nature. The Park adjoins a few nature reserves with unique nature and they provide excellent opportunities for outdoor recreation.
The Koster Islands and the surrounding Kosterhavet National Park offer amazing opportunities for kayaking. All the way from Ramsö and Ursholmen in the south to Saltholmen in the north are lots of small islands and rocks with inviting channels, rocky bays and beaches to explore.
