Thurgau is a canton in northeastern Switzerland bordered by Lake Constance, the Rhine River, and Germany to the north. Known as a winemaking area, it’s characterized by vineyards, orchards and hills. The town of Kreuzlingen shares a border with the German city of Konstanz, and marks the beginning of a lakeside road through towns full of half-timbered houses, such as Gottlieben, Steckborn and Berlingen.
