Western Switzerland’s most important river originates in the Gotthard Massif – where the rivers Rhine, Reuss and Ticino also originate. On its westward course, the country’s best vineyards accompany it for a large part.

Geological trail through the Zügen gorge

An insight into the geological development in the Zügen gorge, between Davos-Monstein and the "Bärentritt". Old valley road closed to motorcar traffic, set in cool shade due to the narrow, deep valley cutting. Above us, the Rhaetian Railway, which negotiates the gorge across viaducts and through tunnels. Carries on towards Wiesen, then continues on the nature trail to Filisur.

People who are familiar with stones and rock formations will walk through the mountains as if they were reading a book on geology.

Naturalised River Thur

Beavers, frogs and butterflies, white willows and orchids: now the region at the confluence of the Thur and the Rhine has been returned to nature, wildlife is flourishing again.


The Thur is Eastern Switzerland’s predominant river. Coming from Toggenburg, the river flows in a large arc beside the rich cultural and scenic landscapes of the Cantons of St. Gallen and Thurgau and parts of the Canton of Zürich.
