The beautiful Koster Islands are Sweden's most westerly populated islands with only around 300 year-round inhabitants and almost no car traffic. Sustainability and ecology are key values here and visitors flock to the islands’ sunny climate and natural attractions. The surrounding archipelago, with its seal colonies, skerries, and rocky isles, is a unique environmental treasure. The islands’ focus on sustainability and local traditions is especially evident at Koster Gardens on South Koster, operated by a collective of environmentalists dedicated to inspiring its visitors toward a more sustainable lifestyle. The prize-winning restaurant was built with materials such as straw and earth and is open year-round, serving lunch and fika (coffee break) from the best ingredients available from the garden and sea. Guided tours are arranged on foot, by bike, or kayak.
