This viewpoint is located on the highest point of the Swiss Belchen on the border between Baselland and Solothurn and is best reached on foot. There are no public transport stations nearby. A car park is available 5 minutes on foot below the Chilchzimmersattel. From there it is a 15-minute hike to the Belchenfluh. 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.

The wooded 1041.8m high Lauchflue is a somewhat independent peak in the Upper Basel area. To the north it has a rock face up to 80m high, which gives you a beautiful view of the Ergolz Valley and the Black Forest. To the southeast lies the slightly higher Schällenberg (1064m), which is separated from the Lauchflue by the Lauch saddle (1014m). The Lauchflue is easily accessible via hiking trails (T1), and on the summit there is a military observation facility from the time of the First World War (Fortification Hauenstein). Trivia: The lid of the observation post comes from the boiler of a steam locomotive. https://www.hikr.org/wiki/post10006.html

A real highlight after a hard climb, for example from the Waldenburg ruins. The climb is a level T2 with a few trial passages in T3. So be sure to bring good shoes and sufficient fitness.

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.
