HI, you may have all the info you need on this now but as we are new to the forum, we will add out bit. Grandvalira area (Pas de la Casa, Soldeu & El Tarter) have 3 snow parks one in Pas, one in El Tarter and a newer evening floodlit park called Sunet Peretol which is between Soldeu and Pas. All are included on the normal lift passes.
We are based in Andorra so any other questions, we will try and help with. Gemma
