Schwägalp Pass, Mountain pass in Eastern Switzerland.

Schwägalp Pass is a mountain pass at 1,278 m between Nesslau-Neu St. Johann in the Toggenburg and Urnäsch in Appenzell Ausserrhoden; the road's highest point, 1,299 m, lies southwest in the municipality of Nesslau. The pass is flanked by the Säntis (2,502 m) to the southeast and the Hochalp (1,530 m) to the northwest. The valley station of the Schwägalp–Säntis aerial tramway stands at the road junction, and the 21 km pass road has a maximum grade of 12 percent.

The road over the pass opened in 1935 to connect the cantons of St. Gallen and Appenzell Ausserrhoden. This project improved access between the two regions and their communities.

Farmers use the high meadows to graze cattle and produce cheese during the summer season. The landscape shows traditional mountain farmsteads and the sounds of grazing herds are part of the daily rhythm here.

The road has steep sections with gradients up to 12 percent, so careful driving is important. Visitors can reach the area on foot, by bicycle, or by car depending on which route they choose.

The Säntisweg, laid out in 1872, climbs from the Schwägalp to the Säntis summit and is the shortest of the mountain's many ascent routes. It is an alpine hiking trail, not a road, and demands sure footing.
