First of all, the trail map posted here doesn't reflect the actual difficulty levels.
For example, trail no. 9 is blue (here red) and is indeed blue except for the final section. Meanwhile, the trails at the highest point on the right/upper side of the map are red. Trails no. 10 and 13 aren't super difficult, they're quite reddish. I don't know about the remaining trails, unless you count the fact that they're closed and the snow isn't packed enough for freeriding, so you can fall and kill yourself on regular carving slopes (been there, done that). And that's a shame, because trails no. 1 and 4 were closed and unprepared. I basically did everything in one day with the kids, so after three days of fun here, we changed our spot to Kals am Grossglockner, even though we had 1 hour (70 km) there and 8 minutes here. But it was also a bit of a challenge to ski different places.
