The German-Luxembourg Nat'Our-Route is a cross-border hike in the Luxembourg Nature Park Our and the German Nature Park Südeifel. After a steep climb to the plateau of Wahlhausen, you are rewarded with a beautiful view of the Our valley. The descent to Gëmund goes through the Aketscht nature reserve over narrow paths on a ridge. On the German side, the walk takes you through the beautiful valley of the river Irsen, which is also known as the valley of the 1000 butterflies.
