The tour leads right into an interesting section of the Donau-Auen (European protected area). You will pass an old fort surrounded by an oval moat and standing on an artificial island. There are waterfowl and beavers. Parts of the trail may be flooded after prolonged rainfall. In places, the path narrows to a narrow path, over which fallen trees lie and which is lined on the left and right by vegetation, some of which is tall. Long pants and tops with long sleeves and sturdy shoes are therefore recommended, also because of the many mosquitoes. The atmosphere is jungle-like. You should have very good local knowledge or a working navigation system (battery!), otherwise you can get quite lost.
