Chäserrugg Summit Restaurant at 2,262 m above sea level / Panoramic views of 6 countries Refined cuisine with panoramic views of 6 countries – the summit restaurant by Herzog & de Meuron offers unforgettable moments at 2,262 m above sea level, whatever the weather. Even during construction, the mountain station set an example: out of respect for the environment, all materials, with the exception of the crane, were delivered by cable car. Sustainability is essential for us, and we are committed to using regional and seasonal products. The entire restaurant is wheelchair accessible and easily reachable by cable car for people with reduced mobility.

In summer there's a coffee machine, in winter only Nescafé. But still.

A cold air pool often forms here, which meteorologists have used to proudly announce the lowest temperatures. It's a depression, and all photos showing a lake are incorrectly placed for this "tip."

This magnificent mountain ridge represents the last section before Mount Säntis. A steel cable has been installed for safety on some sections of the trail; sturdy footwear and a head for heights are therefore strongly recommended. However, no special equipment is required.

Berghotel Alp Sellamatt, Alt St. Johann For more than 60 years, the Lötscher family has run the renowned mountain hotel on Alp Sellamatt. Three generations live and work under one roof. Grandparents Hanni and Valentin Lötscher handed over the reins to their daughter Christiana and her husband Heinz on November 1, 2015. Christiana has followed in her father's footsteps. She trained as a chef and, by attending hotel management school, acquired the necessary skills to continue running the business. She cares passionately for the culinary well-being of hotel guests and day-trippers. She is also the mother of Severin and Michelle. Both attend school in Alt St. Johann and are growing up in the family business. Heinz works at the buffet and reception and is responsible for all technical matters, while Magdalena, Christiana's sister, comes to the Alp from Unterwasser two days a week to manage the accounting and various administrative tasks. Long-serving employees support the family in all areas. The mountain inn was built in the 1940s during the construction of the mountain railway. It was then called the Churfirsten Mountain Inn, and various innkeepers ran the inn before the "Lötscher dynasty" began, until Christiana and Magdalena's grandmother, Margaretha Lötscher-Jöhl, was able to buy the business in 1953 and, from then on, ran it with her son Valentin. Life on Alp Sellamatt was strenuous and time-consuming. At that time, a mountain inn had to be run without electricity or water. There was also no access road. Materials had to be transported from the valley to Alp Sellamatt by train or on foot. The effort paid off! Gradually, investments were made that made daily work easier.
