I have to agree with John about the Ski Welt, it is an interesting and wide area. John and I both stay at the same end of the village, and it is an easy journey into a good choice of access points. I ski there every season, and most years, jump off into Kitzbuhel to catch some of the Hahnenkamm action.
I know John likes Westendorf, as do I. I also like some of the small areas on the Welt such as Going. I always seem to make it back to Niederau for the final run of the day, though!
It is also easy to drive through the Welt to St Johann and the other local villages.
I also have yet to have a good day in Alpbachtal, I guess it just depends on the day you go.
