Pas de la Casa has an excellent English-speaking ski school and wide, sunny slopes on which to learn; so it's a good choice for beginners. Once those first turns have been mastered, there are numerous easy green runs on which to totter around. The largely easy-to-ride high-speed detachable chairlifts or walk-in gondolas take beginner skiers back up the slopes without needing to master the dreaded drag lift too early on.
Progressing on to the wider Grandvalira area, roughly two-thirds of the terrain is in the form of wide, fast blues and reds above the treeline, which are perfect for confident intermediates.
Experts, meanwhile, have more than two dozen black runs, including the toughest run, the 2km-long (1.2 miles) Avet No Fifteem. Accomplished skiers can also try heli-skiing, or an off-piste powder course with the ski school when snow conditions are right.
Despite its southerly latitude, the high altitude of the Grandvalira ski area, its mostly north-facing slopes, and its extensive snowmaking have been proven to provide snow cover over much of the terrain even in poor snow years. The ski season in Pas de la Casa typically runs from early December until late April.
Grandvalira and the other Andorran ski area, Vallnord (which covers three resort bases at two other ski areas), participate in the Ski Andorra lift pass, which is valid at any ski area in the principality.
