Southeast of Zurich and west of Chur, the Obersaxen Mundaun ski area has 30+ pistes served by 18 lifts accessing a maximum vertical descent of 1,000m.
The Obersaxen-Mundaun ski area is located southwest of the town of Ilanz. It is slightly up on a plateau and accessible via ski bus. There are several base areas including Sasolas, Valata, Misanenga, Chummenbuhl, Meierhof and Vella. While snowboarding here, watch out for the runs off Piz-Sezner summit (#46/#47) -- some lead to Areass with no return lift.
After a long morning of snowboarding, try the Berghutte Piz Mundaun, Restaurant Wali and Berggasthaus Triel.
