It's a lovely place to go for a walk. However, the main path is a combined cycle and footpath, so you can't really walk side by side as there are always cyclists on the road. That's a real shame.

For the Siegauen you should actually take some time for flora & fauna. Coincidence or not, I even saw a couple of storks in the meadows.

Especially in the morning it is very nice to cycle in the Siegaue. The paths are well developed and the floodplain itself is very well maintained.
