Very nice place to ski. Just 2 hours from Zurich. Arosa is connected to Lenzerheide, which gives you plenty of slopes. The slopes are from beginner level to challenging. I was not able to find any really difficult or extreme slopes. The longest runs took 20 minutes. I would go here with my children 9 and 12.
Awesome ski resort, easy access and many ski pistes
Very nice infrastructure, but buying single tickets for winter hikers (downhill summit to valley) is an issue. Often retour tickets are sold instead of single tickets and no refund is given on retour tickets used only in one direction.
Nice ride with cable rail way
Great slopes, nice walking routes
