By car:
Use the motorway A7 Ulm - Kempten up to the motorway end, exit Lachen
From there you come after approximately 10 km over Hopferau to Hopfen am See. In addition, you can use the federal highways B309, B310 and B17, which brings you directly to Hopfen am See. If you have time enough we recommend the B17, a romantic road from Würzburg to Füssen.
By train:
For your travel planning with the train we recommend the server of the Deutsche Bahn. Enter there as destination „Füssen“.
