From Hanover we had a 7 hour drive to Grossarl. The motorway/interstate goes until Salzburg. From there it is just about one hour through the valleys...
Our pension was near the slope, so we could start skiing from there. If you live away from the slope you always can take the Ski bus. I'ts running twice every hour.
