Not too big, but very family friendly. And a walhalla for ski mountaineering and Freeriding
Glacier Ski area so snow is guaranteed. Mostly red and black slopes, including the famous Black Mamba. Also some very nice freeride routes.
Home of the famousHahnenkammrennen. Large area with lots of variation. Accessable within 15 minutes from Hollersbach or Paß Thurn
Large resort with lots of variation. Some very nice and wide beginners slopes at the Areithbahn.
Nice Family ski area. Longest illuminated toboggan run in Europe.
A bit further away but with 270km of slopes definately worth a visit.
