Enjoy a brisk cycle through the verdant floodplains of Thur, followed by the neat little old village of Bischofszell and tranquil green plateaus in the Fürstenland, with its deep gashes carved out by streams. The area around Gossau is alive with agriculture. After pedalling through the industrial belt and over the Sittertobel ravine, this leg ends in the hermitage city of St. Gallen.
