I am a regular weekend skier at Whistler Blackcomb from opening date to late May. I skied at Valle Nevado from June 22-27, 2008. Compared to WB, VN has smaller terrain, significantly fewer runs and much slower chairs but virtually no line ups at the lifts and restaurants. The runs were wide and groomed and are quite long. However, the layout of the mountain is not very well connected, especially when low visibility, hard to know which rope tow /poma connect to which run. Also, there is only one fast quad chair (the Andes Express). The "black" runs are not really that difficult, more like "blue" runs at Whistler. None of the runs had moguls. I tried to ski off-piste away from the groomed runs. The scenery of Los Andes is beautiful and I can see Santiago from the distance buried under the black smog.
