OBERSTDORF Radtour von Oberstdorf über Fischen nach Sonthofen , zurück über Altstätten

A relaxing bike tour. The route follows the Trettach River to the source of the Iller. The Iller accompanies us to Fischen and Sonthofen. For the return trip, we chose the high-altitude road via Altstätten and Rubi. The weather cooperated; we enjoyed a pleasant 23°C.
