Niederau has its own ski area, with valley run. There are practice slopes and 2 ski schools with children's area for the little ones. From the Markbachjoch and Lanerköpfel you have very nice runs to the village, especially red and a few black runs. In short, something for everyone and a real family ski area. Niederau also has everything: ski rental, après-ski, restaurants, shops etc. A week is over. If you want more than the ski area in Niederau, a gondola to the Schatzberg / Alpbachtal is nearby in Auffach, for even more kilometers of skiing.
If this is not enough then from Niederau it is very easy and just as fast as to Auffach also reachable the area of SkiWelt Wilder Kaiser-Brixental from Hopfgarten and / or the slightly further situated KitzSki-Kitzbühel / Kirchberg. You will need a slightly more expensive ski pass than just for Ski Juwel Alpbachtal
