There are a couple, one in Grau Roig just over the mountain from Pas, and another over in Soldeu which is a bit further - you need to ski/snowboard to them. It's as it sounds, an igloo where you can get drinks! They also have an igloo hotel where you can spend the night!
To find them go to our piste map, then open the interactive map and you can click to display the igloo bars and hotel.
My girlfriend asked me to do some looking around for something called an Iglu bar?! I don't know if this is in Pas or what it entails, so any information would be great and i'd be extremely grateful.
