The entrance fee to the castle is 11 Swiss francs. It mainly introduces wine and the history of the castle. You can enter or not. It's not bad to see the grape fields around the castle. If it is winter, the surrounding hills are covered with snow, and the castle against the snow-capped mountains is enough.
In the Swiss Alps, the castle is a meter high on the mountain, very big and old. The old castle that existed in 1100 has a very long history. If you have the opportunity, you must visit it. Only 47 kilometers southwest of Lausanne
