KONUS - The Alpirsbach Guest Card
KONUS – guest card plus free public transportation
You are entitled to freely use busses and trains in the Black Forest area during the duration of your stay in Alpirsbach.
And that's how it works:
As soon as you register with your host, you'll receive the Black Forest guest card. The guest card is provided with the KONUS symbol which allows you to freely use public transportation. You'll just pay the tourist tax.
The KONUS guest card is valid during the period of your stay in all participating transportation services such as bus and train (except for ICE, IC, EC, and mountain railway).
