It is a contemplative route with well-paved paths through the Wertachau forest and on Wertachdämmen. A shorter section leads over slightly narrower forest roads, but even there senior citizens ride sovereignly on their e-bikes. It is certainly a bit soggy with rainy soil. At another point you drive over bumpy old tar road (so at the height of Bobingen) - so nothing for speeding with heavy luggage.
As a small search task: Who finds the nutcracker on the track? Tip: There it is particularly bumpy ;-)
