The second gorge after the Devil's Gorge. Not quite as spectacular, but still very beautiful.

Although not quite as spectacular as the lower part, it still offers a beautiful and peaceful hike. The path leads through shady forests and past impressive rock formations that create a special atmosphere. After rainfall, the waterfalls and small streams in the upper gorge are particularly worth seeing.

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.

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.

Barbecue area with a beautiful view. A few meters further up, the officially highest point in the canton of Baselland (1169 m). For an even better panorama, be sure to visit the Chellenchöpfli (with panorama boards)
