If you can find the green one ! We've just got back and we skiied all over looking for it eventually found it and it had a big no entry sign across the star! We were told that it's a path made for walkers which they are/have made wider for skiiers.
Having read other postings here, it looks like we were just unlucky, that it was closed, so we'll be looking for it again when we go back on 4th Feb!
