We highly not recommend to drive your own car to the mountain hotel Huggenberg because it's a steep mountain route.
Further it's very difficult to handle the shuttle service and the private cars on the way up and down in winter. It happens again and again, that private vehicles can't move up or down due to difficult conditions and so people park their vehicle somewhere along the street. Therefore it's not possible for the shuttle service to pass.
The operators of the toboggan run request to the guests that they should take in any case the shuttle service.
Thanks for your understanding.
