Contributor hamed.razzaghi created this stunning drone video from an island in one of Sweden's best known lakes. Visingsö is an oblong shaped island in the southern part of Vättern Lake. The lake, which resembles a finger, sits in the south central part of the country. With a surface area of 1.9k square km (about 740 square mi.), it's the second largest lake in the country (after Lake Vänern), and the sixth largest lake in Europe. It's also quite deep, with a max depth of just under 130 meters (430 ft.).
