So what's there to do here?
Activities? Heck, lots to do up there. I lived there for several years. I still miss it.
You can dream about that big yellow warm thing you used to see in the sky, when you were a kid. I think it's called the sun, or something like that. Another thing you can do is participate in the
Pacific Northwest Freezing Rain Festival, it runs from January 1st to December 31st each year. The banana slug races are cool, too. Just don't lay odds & money on any contender named 'salty'. Bad luck, that one is.
Okay, seriously, there's quite a bit to do up there:
spring through fall, whale watching tours (orcas). Incredible experience if the conditions are good & your boat can get reasonably close.
Summertime: fleet week & hydro races. A friend of mine years ago used to build hydroplane boats, but he's retired now. The hydro races are a blast.
Winter sports are great, Snoqualmie isn't too far from where you are. Several smaller mountain towns do really cool tree lighting ceremonies each Christmas season.
All year 'round: Seattle waterfront. (I worked at two restaurants there twenty years ago; they're gone now, I think.) Great food everywhere, and the aquarium is amazing. Also, Pike Place Market.
