What I found very appealing about this area, is the many, many bathing lakes (as opposed to the usually frigid lakes in the Alpine regions) ideal for families and children. Seems the most popular are the Wörthersee (See means lake in German), Millstätter See, Ossiacher See and Faaker See.
Klagenfurt, the capital of Carinthia, and Villach are the largest towns in the region and can be used as a home base for exploring other lakeside villages. Most train connections will come through Klagenfurt or Villach. There are also medieval towns like Friesach and Gmünd nearby if you prefer to station yourself in a smaller, more charming place. Besides sunny beaches on crystal-clear bathing lakes, in Carinthia you can explore cathedrals (Gurk or Maria Saal), abbeys (St. Paul's, Millstatt or Viktring), castles and palaces (Hochosterwitz, Griffin or Porcia).
