I went to Chile this summer on a ski trip. I skied Valle Nevado and Portillo. Cool mountains with lots of snow for a south pole winter. They even had a decent park at Valle Nevado with a good size halfpipe. It was better than what my local mountain(Avila, Qc) offers me park-wise even after 3 month of snow fo sure....
And as I noticed, in Chile, skiing is pretty much only for the rich and famous...
