I live in Kempten and I crossed the Illerradweg off my list a long time ago; it's just boring and leads through the forest most of the time. What difference does it make that the Iller flows there? None. The paths on both sides of the canal and the Iller can be a bit confusing. The Illerradweg only becomes beautiful towards the south from Ferthofen and Kardorf onwards, thanks to the hilly roads.

My brother from Memmingen and I have crossed the bridge off our list. The 2-step staircase is quite a workout with a 30 kg e-bike and/or panniers. The bridge path is rather narrow, and with mirrors and panniers, it can get tight when there is oncoming traffic. So, pray that no one is coming.

My date from 2025 was total nonsense, my brother and I cycled in 2026 towards Buxheim to the construction site when the construction workers had finished for the day. Do not ride during the day under any circumstances, it is far too dangerous. The detour via Heimertingen still exists and probably also until next year. It could become really beautiful when it is finished, whenever that may be.
