Further information The famous "Belchenflue" viewpoint was used as an observation post in World War I and was blasted into its current form. The Belchensüdstrasse between Ifenthal and the Belchenflue commemorates the troops involved in the construction with numerous coats of arms, which immortalized themselves in the rock after the work was completed.

Since the Wiesenberg is in the forest, this observation tower makes sense. It takes hikers above the treetops and allows a 360-degree panorama. There are panorama boards. The climb is worth it.

The path to the Gwidmenflue requires sure-footedness on both sides, but is easily doable with the necessary caution and concentration. Particular caution is required when it is wet as the rocks become very slippery. Once at the top, you can explore the old military facilities and enjoy the wonderful view.

During the Second World War, this tower was used as an air observation post. The forest grew higher and higher, making it necessary to expand the tower. In 1953, it was increased by 6 meters and in 1987 by a further 9.5 meters.
