In our area cross country skiing is a common alternative to downhillers.
In Langenwang are slopes as well. There are made by the municipality as soon as there is enough snow. Then you can reach it easily from the Gästedorf.
For longer and more challenging slopes you need your car to reach them.
Try for example the track on the Alpl. It is very beautiful!
More on cross country skiing in the region is put together here.
