TripleBlackMont Ste marie got a bunch of new rails last year so the park might be a bit better than previous years, but still very small.
Lots of fun to be had on a pow day, and even the groomed runs are really nice compared to anything else in the area (and the lifts are very fast without long lineups). The park will disappoint you if that's what you're looking for but it's still worth the drive for the non-park terrain.
Never been to Ste Anne, but I'd definitely like to go some day, heard good things about it.
Ste Anne is very good. They have a lot of great rails. Even had a triple kink which I'd never seen at a hill until then. The only problem is/was they had no jumps which was dissapointing and I wasn't great at rails last year when I went so it wasn't as fun as it will be this year.From what their site says, this year they have 34 features, and you can hit 17 each park run without hiking. They have a hard and an intermediate feature beside each other. I really like that idea. The only thing about St. Anne is, the hill is so amazing that I don't want to ski park there as much but my friends make me.
