The vineyard hike leads from Oberneunforn in the direction of Frauenfeld along the famous Iselisberg vineyard. The high-level trail offers a wonderful view of the Thur and, in good weather, you can even see as far as the distant Alps. The many vineyard cottages along the route are particularly beautiful. At the end of the hike, a stop at the popular Ittingen Charterhouse, the former Carthusian monastery, is a must. The old monastery walls now house a hotel, the Mühle restaurant, museums and a farm with its own cheese dairy, butcher, bakery, market garden, fish farm and vineyard. Delicacies are conjured up in the restaurant using the farm's own produce. A glass of wine from the Ittingen vineyards is highly recommended.
