Illerdamm circuit, mostly paved

From the resort, we first pass the Sonnenalp golf course towards Muderbolz. There, we turn left onto a section of the "Allgäu Bike Route" to Dietrichs. In the next town, Untermühlegg, we continue straight on to Obermühlegg.  From there, we go down to Obermaiselstein, past the hamlets of Ach and turn left at the town entrance over the "Hirschsprung" to Tiefenbach near O. We stay on the main road and ride to the left of the Breitach (on the bike path), past McDonald's and just before the Iller bridge we turn right under the B19 underpass onto the Iller embankment. We ride past the source of the Iller and stay to the left of the Iller until we cross the two tributaries (Schönberger and Weiler Ach). There, we turn left to "Weiler" (passing the nursery). We go under the B19 and then turn right to Weiler. From there, we continue straight through a climb into the forest area before Tiefenberg. In Tiefenberg, we follow the road to the Hotel Resort Sonnenalp.
