Geo-Route: Stage 1

From Romanshorn, the route takes you through the enthralling Oberthurgau region. The landscape here is dotted with gentle, rolling hills, born from ice-age glaciers eroding the rocks. Along the way, you’ll see why we also have those glaciers to thank for today’s wine industry. Passing through Sulgen, the route reaches the rich gravel and groundwater reserves of the Thurtal valley.
