The tour starts at the GEOMuseum of Radein, near the parking space behind the church. We follow the road "W", called Zirmersteig, to the Lahnerwiesen. On the way you can enjoy wonderful views into the GEOparc Bletterbach canyon. Following the forest road through mountain pines and across boulders we reach the top of the Weißhorn. 360° astonishing view to the tops of the Dolomites, the Sarntaler Alpen, the Brenta-mountains and the Texler-mountains.

After the break a road in the south goes down to the Jochgrimm, from there we follow the road 7 over fresh meadows back to the start point.
