We went snowboarding in Saalbach, Austria (next to Zell am See, which is great too) this spring. The spring was early so there was only snow on top of the mountain, but it was still great.
I went there couple of years ago during winter, and it was awsome.
Might not be the best place, but I sure like it.
There's couple of snowboard parks, natural half pipes and jumps, lots of cool forest to board in, off-pist, and great after-ski
I will definitely go back there this winter again.
