Attractions for kids San Fran to Seattle

[Win]

HI,

I'm taking a road trip with my seven year old son from San Francisco to Seattle in two weeks and wondered if anyone could suggest interesting routes and especially any interesting sites/activities/destinations for kids on the way?

Driving through the huge drive-through Redwood in Redwood National Park

Riding dune biggies at the Oregon Dunes National Recreation Area

River rafting on the Rogue River

The Oregon Caves

The Oregon Vortex near Gold Hill, OR

Newport, OR: great aquarium, Ripley's Believe it or Not, Undersea Gardens

The Sea Lion Caves

Take wind-surfing lessons in the beautiful Columbia River Gorge...especially in the Hood River area

Mt. St. Helens

Museum of Flight in Seattle

Riding any of the ferries or harbor cruises in Seattle

Paddle a kayak or canoe in Lake Union in Seattle

Ye Olde Curiousity Shoppe on the waterfront in Seattle

Space Needle

These are just a few things most kids should enjoy off the top of my head. If you want more specifics, please let me know.

We just returned from a similar trip...last night, actually! I'm assuming you're taking the 101. If not, please do! We took the I-5 north, and man was it boring! The 101 is all kinds of interesting. Our favorite stops:

Trees of Mystery
Devil's Churn State Park, which we found quite by accident. The website says plan several hours, but we spent about an hour at high tide and that was sufficient.
Tillamook Cheese Factory; my 7-year-old son's top pick.

Have a great time!
