About Kosterhavet National Park

Kosterhavet National Park is Sweden’s first marine national park, offering a rich underwater world and unique coastal landscapes ideal for kayaking, diving, and wildlife observation.

Wilderness Landscape & Natural Heritage

Located off the west coast of Sweden in the province of Västra Götaland, Kosterhavet National Park was established in 2009 as the country's first marine national park. It encompasses the Koster Islands and the surrounding sea area, extending to 4,000 hectares of protected marine and coastal environments. The park’s geography is characterized by a combination of granite bedrock, shallow fjords, and deep trenches, which creates varied habitats including rocky shores, kelp forests, and nutrient-rich waters. This environment supports a remarkable diversity of marine life, harboring over 6,000 marine species, including rare sponges, sea anemones, and vibrant fish populations. Kosterhavet is also significant for its population of harbor seals and seabirds.</br></br>Visitors are drawn to Kosterhavet National Park for its extensive opportunities for marine recreation. Snorkeling and scuba diving are popular activities due to the clear waters and biodiversity. Kayaking around the archipelago offers scenic views of rugged coastlines and marine fauna. Hiking trails on the islands provide exploration options of coastal meadows and forests. The park also includes several small fishing villages that highlight the cultural heritage of the region. Throughout the year, wildlife viewing including birdwatching and seal spotting remains a key attraction. The combination of coastal and underwater environments offers a distinctive nature experience that balances conservation priorities with sustainable recreation.
