The run right from the mountain bar "Jazz Hütte" at the top of the "Jazz Quattro" lift is a pretty short run, but offers technical terrain.
This area is also used by swiss speedriding schools to train beginners. A good place to meet other pilots. And because its all right next to the lift, you can do up to 60 runns a day.
