Mittelallalin, Mountain summit above Saas-Fee, Valais, Switzerland

Mittelallalin is a 3,456-metre summit below the Allalinhorn above Saas-Fee, with a dark rock face cutting diagonally across its snowfields. A rectangular building with a dark pitched roof and a row of windows stands on a rocky ridge in the foreground, supported above the snow on a small platform.

The Metro Alpin funicular, the highest in the world, has run from Felskinn to the Mittelallalin summit station since 1984. It made the 3,456-metre summit reachable without climbing, and the revolving restaurant Allalin, seating 200 and turning once an hour, is part of the same complex. The summit also holds a memorial to mountain guides at about 3,500 metres, among the highest in the Alps.

The station at the top houses the world's highest revolving restaurant, where guests can enjoy traditional Swiss alpine food while looking out over surrounding peaks.

The journey to the top uses a combination of cable cars and the Metro Alpin funicular, all starting from the base station in Saas-Fee. Bringing warm clothing is essential since the temperature drops significantly at this elevation.

The glacier cave lies inside the Fee Glacier beside the Mittelallalin station, cut into the ice rather than formed by nature. The revolving restaurant above it seats 200 people and completes one full turn every hour. On clear days, Milan lies only 120 km away in a straight line, and its lights can be seen from the restaurant.
