Tastes differ and that's a good thing, but as a Kempten resident I have struck the Illerweg from Hegge via Martinszell to Stein from my list because it leads a lot through the forest and the mountain view is limited. I don't need to go to the beautiful Allgäu for routes through the forest. The route to Martinszell is one of my favorite routes.

There are people who use the path as an everyday cycle path. Every day, in all weather. If you only cycle in the best weather, you will certainly not have any major problems with the path. If you want a change in mobility here, you also need the appropriate paths for it, suitable for everyday use, suitable for all weather, and we don't have them.

Really sad, Bububaer only publishes rain pictures, best to ignore him. Worldwide many dirt roads are "muddy" in the rain and they will dry again.

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.
