Check out this stunning drone video of Turkey's Lake Salda, compliments of top contributor dronesantana007. Salda is a crater lake in Burdur, one of the provinces which makes up the country's Mediterranean (southern) region. The lake covers about 44 square km (around 17 square mi.) and it's quite deep - almost 200 meters (around 640 ft.) at its deepest point. The lake is a popular destination in southwestern Turkey, and its waters are believed to have medicinal value.
