Katschberg and Obertauern are two mountain passes, normal stops on the road before the Tauernautobahn was built between Salzburg and Villach. Even if centers of both resorts are on approximately the same altitude and there is just about 20 km distance between them as the crow flies, the Obertauern gets a lot of snow and Katschberg is often barren.
So you have to wait for good snow conditions - patches of stone and flanks of ice are really a nuisance. On the slope of Tschaneck (2030 m) there are many runs but lie parallel to each other and are not much varied. On the other side of the pass there is a connection with St. Margarethen in the valley over the Aineck (2220 m). From the top of the mountain there is nice view but the resort itself does not give very mountainous feeling if you don’t count the often present cold wind. There are two or three nice long and a bit steeper runs here but the lifts are old and slow. Children run with all the animals is located just below the pass and is sheltered from the wind.
Resort itself is small and it is more likely to find accommodation in the Lungau valley - this way you can use whole ski region Oberlungau or Lungo (Oberlungau + Obertauern). Overall, me and my friends don’t like the scenery in Katschberg too much and rather drive for another 20 minutes to reach Obertauern…
