What's the best place to go skiing during late April in the northwest?
At this point you might as well go to Oregon, Mt Hood Meadows or Timberline have easily affordable spring passes. You can camp 4 dayz and get your money's worth in only 1 or 2 days of shredding at either resort. Some stay the entirety of the spring pass, some go for just a week and its pretty good deal. Both have parks that are on fire during spring, both have good terrain (You just have to look for it at Timberline but it's there). Only deal with Meadows is the offset corporate vibe that they have. They will most likely treat you as inferior compared to their winter crowd (rich loaded Californians). Timberline is a more family fun, and local fun vibe. They love all their guests from dirtbags to loaded Californians... so long as you pick up your trash and keep your camp clean.
Spring is pretty good on east coast, especially Sugarloaf Maine for reggae fest, hella dope, hella fun, hella good skiing
