Millstätter See is the second-largest lake in the Austrian state of Carinthia, spanning 12 kilometers in length. It is characterized by its deep, steep-sloping basin, reaching depths of up to 141 meters. The lake is known for its high water temperatures, which can reach 25°C in summer due to its sheltered position within the Nock Mountains. It is a glacial-origin lake surrounded by forested slopes and meadows. The area functions as a central hub for water sports, including sailing, rowing, and stand-up paddling. The surrounding landscape features the Millstätter Alpe, a high plateau providing panoramic views of the surrounding valleys. Unlike many other alpine lakes, the southern bank remains largely undeveloped and preserved as a nature reserve. The lake holds significant mineral content, and its microclimate is often described as Mediterranean-influenced.
