From Trogen, head down into the Goldachtal valley and follow its course until you reach Zweibrücken. The steep climb towards the village of Rehetobel will be rewarded with unbeatable views across Appenzellerland and the Alpstein. At the turn of the 20th century, this village was a hub for small-scale textile manufacturing. Carry on via the Kaienspitz viewpoint with its sweeping panorama, past Lake Constance and into the Alpstein mountains before going down into the Biedermeier village of Heiden.
