Koster Islands, situated 10 km west of Strömstad, Sweden, comprise an archipelago surrounding the two largest islands, South Koster and North Koster. The islands have a unique landscape dominated by smooth bedrock, bearing witness to volcanic activity and subsequent wear due to the Ice Age. The rocky coastline is broken by many sandy beaches, with the largest being Kilesand on South Koster's east side, overlooking the 200-meter-deep Koster Fjord. The islands are home to a permanent population of around 340 people and offer various amenities, including a school, sports hall, shops, church, and galleries. Visitors can enjoy activities such as sailing, fishing, and exploring the islands' trails and beaches. The Kosterhavet National Park, which includes the sea and shores around the Koster Islands, is home to Sweden's largest seal colony and over 6,000 marine species, making it a great destination for nature lovers and families

Highlights: The active and nature-loving kids loved the boat trip and exploring by bike. The viewpoint at Valfjäll was great for us adults, with its stunning views.
