Before climbing the Lägerngrat, it's worth taking a break at the Schartenfels Castle Restaurant 🍽️🏰. With its sunny terrace and magnificent views over the Limmat Valley, it's the perfect place to refuel with a coffee or light lunch—in style and with a view—before heading up the narrow ridge path.

Habsburg Castle is the cradle of the Habsburg dynasty. This is where it all began. Today, the castle is home to a great restaurant that takes up most of the castle's rooms. The complex is therefore open all year round and can be visited free of charge. However, you won't find an extensive museum or dozens of rooms here. Only the palace (tower) and the outdoor area, including the outer castle ruins, can be visited. A small shop at the sod fountain offers the opportunity to buy souvenirs, books and the like. You can even rent VR glasses that show the viewer virtually what the Habsburg once looked like. The view from up here is breathtaking, by the way. Autumn in particular has its colorful advantages. The castle can also be easily reached by car. There is a sufficiently large parking lot. Anyone who is out and about as a hiker or biker will get their money's worth in terms of the route.
