Kärnten is known for its ski resorts as well for its scenic lakes and mountains hiking, climbing. If you are travelling in summer try out one of these lakes:
Carinthia
Wörthersee - Austria's biggest lake, a popular resort for German tourists and the location for various German and Austrian film and TV-series productions. Prices tend to be higher than elsewhere in Carinthia due to its importance to tourism.
WeiÃensee
The highest-altitude swimming lake in the alps 930m above sea level with crystal clear water, beautifully situated in a fjord-like valley.
Skiing resorts include Nassfeld at the Italian border, Turrach at the border with Styria, Flachau and Katschberg both bordering Salzburg. Skiing is a bit cheaper than in Tirol and Vorarlberg.
