National Geographic Travelさんのインスタグラム写真 - (National Geographic TravelInstagram)「Photo by @justin.jin My twin nine-year-old girls, Jasmine and Sienna, balance themselves on rocks on a beach in North Koster Island, a protected reserve off Sweden’s west coast. The Koster Islands are situated 10 kilometers (six miles) west of Strömstad and comprise an archipelago surrounding the two largest islands, South Koster and North Koster. North Koster has an area of four square kilometers (1.5 square miles). The landscape, dominated by smooth bedrock, bears witness to volcanic activity and subsequent wear due to the Ice Age. The rocky coastline is broken by many sandy beaches. This picture was shot near midnight, as the sun sets late in Scandinavia during the summer.
