Koster – a marine national park
Kosterhavet is one of Sweden’s 29 national parks. Inaugurated in 2009, it is the first marine nature park in Sweden. It is part of the Skagerrak sea and consists of the sea and shores around the Koster Islands. It contains coral reefs and a unique flora and fauna, making the park a great snorkelling site.
