I live in Kempten and the Iller is definitely not wild, not in any season. I used to be a raft guide in Austria for 4 years and navigated the Sanna and the Ötztaler Ache in borderline conditions (whitewater 5). The pictures from HP show the average or boring water level (whitewater 2) during a rubber dinghy tour. I have also attached some pictures from the 1994 Rafting World Championships on the Zambezi at Victoria Falls in Zimbabwe. Of the approx. 50 teams, one participant drowned during a 2-hour training tour. I reached 8th place with a German team. Maybe Gimmi will change his text to "cozy Iller" and bububaer will end his endless rainy tours because the sun mostly shines.

As Kempten residents, we long avoided it, but the path is beautiful along its entire length from Ahegg to Weitnau. I now use the "Protective Wax" from Dynamic and nearby I discovered a pressure washer at the gas station. On the way, I also spotted a hummingbird hawk-moth. Very small but not a hummingbird. https://youtu.be/V8FgTsvxtio

I am not a fan of country roads and really enjoyed the cycle path. It offers much more scenery than expected and the rare opportunity to cycle many kilometers without climbs in the Allgäu. From Rotkreuz via Ermengerst, Wiggensbach and Buchenberg to Weitnau. From Weitnau there is a cycle path to Missen.

Mostly directly along the Iller and the floodplain areas, it is pleasant to ride and there is much to discover with constantly great views of the Alpine panorama.
