It is situated at 3,260 metres (10,700 ft) above sea level, a few kilometres south-west of the town of Zermatt in the canton of Valais in Switzerland.
In 1911, the municipality of Zermatt built a hut directly next to the Hotel Belvédère (also Berghaus Matterhorn).
It offers 130 beds (in a total of 34 8-,6-,4- and 2-person rooms) and an enlarged kitchen, modernized sanitation with showers and electricity from solar energy.
The new Hörnli hut became the first mountain shelter in Europe to purposely limit the number of beds.
From the cable car station of Schwarzsee (or from Zermatt) a marked trail leads to the ridge and then to the hut.
