A little nature, a little urban, a little old town? Marble combines everything in one trail. In the outer Tiefenau district, the trail leads through the forest and down into the idyllic Felsenau district. Then it goes along the Aare to the Bremgarten tunnel and from there back to the city center. The urban part of the trail takes you on foot across Waisenhausplatz and to Altenbergsteg. After a walk through the old town, you will arrive at Kornhausplatz, where the end of the trail is approaching.
