Two former mills - the Harspelter and the Lützkämper Mühle - can be seen along this leisurely loop, both of which are located on the Irsen. In the Irsen valley, traces of the 2018 floods are still clearly visible in places.
The blown-up bunkers and humps (anti-tank barriers) of the Westwall are also impressive. For a few meters you are also on the Westwall hiking trail Islek.

Please note: The Islek paths are not marked or signposted. Please follow the directions given or the gps navigation!
