Awesome! I love it up here, you'll have fun.
I would recommend some of the following places to visit:
Portland
VooDoo donuts(I'm not from there, only went once, it was awesome!)
Seattle (This'll be a long one)
Pike's Place Market (If you've never been, it's awesome to see at least once)
Mt St Helens (It's definitely off the beaten path, but is a cool sight to see if you are willing to jump off the freeway for a while. It's one hour from I-5, at the point of turn off, so it's definitely a bit of jog, but if you're really interested in that kind of stuff, it's definitely neat.)
Space Needle/EMP (Both somewhat expensive, but cool to see in person)
Museum of Flight (This is the far south edge of Seattle, but is pretty cool. Some of the planes they have are pretty cool to see in person, highly recommend.)
Ballard Locks (I've never been, but I've heard they're pretty cool)
Chinatown (I've also never been, maybe briefly passed through, but it's a pretty neat area from what I've heard. Almost as old as Seattle itself, dates back to the 1880's.)
You should make a point to ride the SLUT. Just to say you did, because why not! It's the South Lake Union Transit, :lol:.
There's also some great food in Seattle, though I only know a couple districts:
Downtown(Or maybe Queen anne?) -
Lowell's (Breakfast, in pikes place, always packed, some of the best breakfast you can get!);
Ivar's Seafood (Down on the pier, legit and fresh)
Capital Hill -
Elysian brewing (Great beer and food. They have other locations, the food is not as good in the other locations);
Li'l Woodys (Great burgers!);
Top Pot Donuts (Staple of Seattle, so good!)
Georgetown -
Via Tribunali (The best pizza I've ever had! Authentic Italian pizza, the owner studied in Italy, knows fluent Italian, and even had the wood fired brick oven shipped over from Italy; shit's legit!);
Slim's last chance (fantastic chili!);
Fonda La Catrina (Authentic Mexican food, not that Azteca crap!);
Alki -
Salty's (Fantastic Seafood!)
I could probably keep going on and on, but I'll end up making this post waaaaayyyy too long :bellyroll:
I'll post up on our facebook group too and point some of the guys here, maybe some of them will want to meet up so you can check out the local VW scene.
I work in the Georgetown district, love the area
Edit 1: You said you like scenic routes, here are some good ones up here. The 101 along the coast is great (south west WA coast). Snoqualmie falls is always neat to visit. I've heard the Chukanut drive is really cool, it's north of seattle quite a ways though, you'd have to look into that one more.
Okay I'm done now until you ask for more :lol:
