Chiemsee is a municipality in the district of Rosenheim in Bavaria in Germany, named after the lake Chiemsee.
In the film we see a Hang Gliding training center, which is a sport, hobby or even a profession in which a pilot flies a light, non-motorised foot-launched heavier-than-air aircraft called a hang glider.
The trainees, as we see, first practice on low sloping hills, where they are taught the basic techniques of the aircraft. In the second stage, having learned how to handle it, they are transported by cable car to the highest point of the hill, from where they start flights at a higher altitude. They enjoy the experience and practice landing.
