I can't really say for vt except that Jay Peak is alright. Waterville Valley and Loon both have sick parks. Sugarloaf and sunday river also have great parks,(sunday river better then sugarloaf) But loon WV Sunday river and sugarloaf all have great parks
loon i was there today and they had like a small but fun jump, an escalator rail, a shotty rail, a flat box, an a-frame box, and a single baral urban. its a lot of fun and deff hikable so you dont have to ride the gondola
