Photo: Johann Jaritz. Keutschach Hoeflein Rauschelesee. My family used to camp here in the mid 60s. At 15, I tried to swim across the lake. Got half way and turned back never thinking that I could have reached the other side in the time it took me to swim back. My parents would have picked me up on the other side! It rains in the summer in these areas - I have never camped since!
