Oberalp Pass ( or Cuolm d'Ursera; ) (2044 meters above sea level) is a high mountain pass in the Swiss Alps connecting the cantons of Graubünden and Uri between Disentis/Mustér and Andermatt.
In winter, a ski area extends to the Graubünden side, connecting the pass well into the Tujetsch territory to Dieni, near Rueras.
Source of the Rhine
The major European river Rhine springs from a source nearby (Lai da Tuma), which can be accessed by hiking two hours from Oberalp Pass. A multiday trekking route is signposted across Oberalp pass and along the young Rhine called Senda Sursilvana.
Oberalpsee is located 20 m below, in the direction of Andermatt.
