Southern ontario is 3 main hills.
Blue Mountain
Mount St. Louis Moonstone
and Dagmar is on the up because of the park hype
If your looking for park, Blue's is ok for rails and stuff, haven't seen the jumps for a couple weeks now. Mount St. Louis' park is always awesome, only checked out dag once, its alright, I wouldn't go as far as "pretty good", especially compared to MSLM.
Blue Mountain
Pros
-Size
-Lots of other runs
-Good park with a dedicated lift
Cons
-Lots of gapers, especially outside of the park
-No aerials allowed
-Expensive
Mount St. Louis
Pros
-Huge park
-Two different parks
-Less gapers
-Aerials
-Not as expensive as blue, if I remember correctly
Cons
-I dont like it much for anything but park
-Thats all I can think of, idk there resort food sucks too
Dagmar
Pros
-Cheapest lift tickets
-Solid park for size of the hill
-I found the park really chill, not intimidating at all (maybe just me)
Cons
-Hill is super small
-Not great runs other than park, mainly due to the vertical
Just my opinions , tried my best but could maybe still be a little biased but if you need anything else PM me.
