If you go hiking, and you are just outside the winter season, on many tracks still snow or ice is present. And many off the tyracks are next to a ridge, so if you fall, you will scrape you off rocks, so be extremely carefull. And always have someone know which track you will take.
There are sometimes avelances, when I was there a little one occured, don't know if anybody got hurt or not. Most off them are caused by boarders who go off piste, so iff you see them, kick their asses big time.
And just listen to the avelance report every day.
It can be dangerous with thousand off people on the slopes, and the most dangerous ones are the beginners. And with that I mean beginners who think they already know it and just go down as maniacs. So always be carefull and watch other people.
The second group off people that are hazardous are the apre ski ones that fill them up with alcohol and go down the slopes, if they hit you you probably will break a leg or so, and they will have just a scratch, that is ironic, I know.
