Dear Visitors

In the Laufental valley near Basel, in the Kaltbrunnen Valley and Brislachallmet region, an "Educational Karst Trail" has been created by the local speleologists' association. The trail leads from Zwingen to Grellingen. Similar to a nature trail, this trail brings interested visitors and hikers closer to the local themes of karst, caves, cave dwellers (humans and animals), archaeology and the protection of the karst landscape.

If you are interested in further information in advance, you are welcome to contact us at the addresses below.

We also offer guided tours for interested groups. More information here.
