Observatory by Randolins

Our historic observatory dating back to 1924 on top of the Chesa Margna has been redesigned in spring 2020 and has become a very special hotel room. The dome can be opened in good weather and offers a fascinating view of the Engadine mountains, the Lake of Champfèr and Lake Silvaplana and at night the starry sky.

You can look forward to an experience that probably no other hotel - at least in Switzerland - can offer.

Overnight stay under the starry sky

The observatory by Randolins is part of the resort-like Randolins mountain hotel and is located high above St. Moritz on the world-famous Suvretta slope. Bike- and hiking trails start almost behind the house, in winter the next entrance to the Corviglia ski area is only about 300 meters away.

In the former observatory at 2000 meters above sea level, a unique sleeping experience awaits you with a direct view of the starry sky and the Engadine mountains. The historical observatory has its origins in 1924 and was converted into an observatory room in 2020. In addition, you benefit from all the amenities of the three-star hotel, such as the breakfast buffet, the wellness area with Finnish sauna, bio sauna, steam bath, whirlpools and infrared cabin, the hotel's own outdoor parking and the free shuttle service (according to our timetable). On request, we will gladly reserve a table for you in our a la carte restaurant Stüvetta or during the day also on the sun terrace.

By the way: It is worthwhile to stay with us a little longer. Because starting with two consecutive overnight stays during the summer season, the mountain railroads and public transport in the Upper Engadine to the Bergell are already included in the room price!
