Most routes from Germany lead to Ulm before carrying on along the A7. Take the Allgäu junction over a section of the A980 to the Waltenhofen junction, then take the 4- lane B19 via Sonthofen and Oberstdorf to Kleinwalsertal. From Austria (Vorarlberg) and Switzerland you reach the Kleinwalsertal via the Bregenzerwald (Hittisau) – Riedbergpass – Fischen – Oberstdorf. From Tyrol the fastest route is over the A7 to Kempten carrying on along the B19 direction Oberstdorf. A motorway vignette is not required to reach the valley.
A parking area (fee required) is located close to the starting point.
