In the highest part of the Oberhalbstein valley is Bivio (1,776 m/5,827ft; pop. 250), so called (Latin bivium, "roadfork") because a busy medieval road, now represented only by a bridle-path, branched off here and ran over the Septimer pass (Pass da Sett, 2,311 m/7,582ft). In Bivio four different languages are spoken: German, an Italian dialect
from the Val Bregaglia, Ladin and the Surmeirian dialect.
Bivio is a town with numerous year-round outdoor activities available such as skiing, skating, snow boarding, fishing, hiking or hunting.
