Belchenflue

The Belchenflue is a mountain of the Jura, located on the border between the Swiss cantons of Basel-Landschaft and Solothurn, south of Eptingen. The nearby Belchenflue Pass links the two cantons.

The mountain is also known as the Swiss Belchen and is part of the so-called Belchen system, a group of mountains with the name "Belchen" that may have been part of a Celtic sun calendar.
