The Les Praeres pass, meaning "meadows" in Spanish, is a beautiful crossing point for the surrounding peaks. There's also a bar and restaurant with a mountain atmosphere. As if that weren't enough, there's a deer, rescued as a puppy by the bar's owner, who freely roams the area like a pet.

It's a beautiful place and a dreamlike landscape. What a shame the shelter isn't working. These politicians we have don't do a single thing right.

Always check the forecast before you go.
