Wörthersee is a large lake in the Austrian state of Carinthia known for warm summer water temperatures and resort towns along its shores. The lake has been a popular leisure destination since the late 19th and early 20th centuries and still hosts extensive tourist facilities.

The water is noted for its blue-green colour caused by fine glacial sediments and seasonal clarity. Popular activities include swimming, boating, lakeside promenades and cycling around the shoreline.

The lake sits in a broad basin south of the Alps near the city of Klagenfurt and is ringed by resort towns such as Velden, Pörtschach and Maria Wörth, which serve as the main access points for visitors.

  • Recreational note: The lake is a warm, lowland Alpine lake favored for bathing and boating during the summer months.

What to See #

  • Velden: A long lakeshore resort town known for its casino, promenades and lakeside hotels; it is a primary tourist hub on the lake's western shore.
  • Pörtschach: A popular lakeside resort and transport hub with boat connections and access to walking trails around the lake.
  • Maria Wörth: A small peninsula and pilgrimage site with a 15th-century church that sits prominently on the lake and is a frequent photography subject.
