To the left of the ridge is the main valley, the Cercle d'Arcalis, which is bowl-shaped and is well populated on its left flank with trees. It also contains most of the lifts, which fan out from the base lodge. These are long blues and reds which run down the second valley, the Cercle de la Coma, which is tree-free. These runs return to the base station around the end of the ridge. Snow reliability is good.
Artificial snow covers the base area and some pistes leading into it.
The height of the area, which starts a good 400m higher than Arinsal, also adds to the length of the season. Of all the resorts in Andorra, Arcalis has the most to offer experts. The black run that leads from the ridge back down towards the base is steep, and often mogulled, while the red run it connects to starts from the top of the main chair, going through a spectacular gulley before widening out. There is also plenty of space between runs for off-piste forays, especially in the Cercle de la Coma. Intermediates are well catered for, with smooth, long blues and reds being the main feature of Arcalis's slopes.
