Lake Ossiach (Ossiacher See) is another wonderful stretch of water worth visiting and is famous for its outstanding natural beauty. 

Just 10 kilometers northeast of Villach, the lake is 11 kilometers long and one kilometer wide and reaches depths of up to 47 meters, making it the third largest lake in Carinthia after the Wörther See and the Millstätter See.

Surrounded by wooded hillsides and mountainous peaks, including the Ossiacher Tauern in the south, this warm lake has long been a popular holiday spot, thanks in part to its many quaint lakeside villages with facilities for water sports such as rowing, waterskiing, sailing, and windsurfing.
