Crystal is the better option from Tacoma, especially for only a day. It will be a lot closer to you than White pass. It's true there is no park, but the terrain more than makes up for it. Plenty of natural stuff to freestyle off of. There's also a jib park if you're into that kind of thing. White Pass does have EPIC tree runs though. If it was me, I'd try to visit my sister for more than one day, or make more than one visit.
