Ellmau
If your are a beginner and/or on a budget then this is the place for you.
Obertauern
Until recently very few UK tour operators offered package deals here however, the year I went to Obertauern we stayed for 3 nights on a long weekend break which we organized ourselves.
St Anton
For me St. Anton offered the best week in the Alps I have ever experienced.
