I just came back from Ste-Anne, and make sure to get up early and go to the park... The rails are nice, the jumps are amazing, everything slides great, I just love the park at Ste-Anne, but make sure you get there early in the morning.
And Massif has like 1 rail, so don't go there if you only ski park. Other than that, the mountain is amazing. Best ski in Quebec, for sure.
