The Säntis is the high point of the Alpstein, 2,502 metres of limestone that rises almost out of nowhere above the rolling hills of eastern Switzerland. The road that gets you to its foot is the Schwägalp pass, which climbs from Urnäsch in Appenzell Ausserrhoden to a high saddle at 1,278 metres and then drops toward the Toggenburg. At the saddle, a cable car carries people up the last steep stretch to the summit in a few minutes, and a famous weather station sits at the top.
That weather station has a long record and a short temper. The summit is exposed to everything the north can throw, and winter storms have buffeted the building and the tower for generations. On clear days, the view takes in six countries, according to the local boast: Switzerland, Germany, Austria, Liechtenstein, France and Italy. You do not need to go to the top to feel the mountain's presence, though, because from the pass the north face looms above the meadows like a wall.
The ride is the main event for many. Coming from Urnäsch, the road climbs steadily through pasture and spruce, with a mix of tight bends and relaxed stretches, and the surface is generally good. Cattle roam in the high meadows, and the clank of their bells carries on the wind. Plan on Appenzell or Urnäsch, and fill up before the climb.
In summer the pass is busy on weekends, with cyclists, motorbikes and sightseers, and the car park by the cable car fills early. Weather is the other variable. The Säntis creates its own, and a morning of sun can turn to cloud by noon. In winter the road is generally kept open, but snow and ice can make it tricky, and the north-facing hairpins stay in shadow. A clear autumn morning, with the first snow on the summit and the meadows still green, is the best of all.
