I've been up to avila, and there park is insane. very nicely built jumps that are big, boxes and rails set up nicely, definetly worth the trip up. If buy snowpass u mean park pass, its 10 bucks at Axis and it lets u in the park for the year.
You only need a pass to get into the park on the avila side, the park at Sauvuer doesnt need anything and all u do to get the pass is fill out a form, ure suppose to be 18 but to my knowledge they dont id
they do not id.. it is 10$, worth every penny.. very nice set up this year, lastnight the pipe was good to go with the dragon... sick booters and very nice jibs
