Suggestions between Portland and Seattle

Mt St Helens Visitor Center
Mt Ranier Park
on the Oregon coast before you leave: Tillamook Cheese and Ice Cream Factory!! They have a cafe there and you can have lunch but save room for ice cream!!
Go north of Bothell to Mulkiteo and take the ferry over to Whidby Island and drive to the north end of the island to Deception Pass, then take the bridge back to the mainland and back to Bothell.

Actually going on Alaska Cruise 5/30 on Princess lines for a week

Thanks for the suggestions

We rode a steam train in Chehalis.

If I understand you correctly... you have 2 weeks until you leave Portland and then once you leave Portland, you have 3 weeks until you need to be on a ferry heading to Alaska out of Bothell, WA.

Before you leave Portland, I hope you get a chance to see Multnomah Falls
south of Portland in the gorge. It's not hard to find at all.

Head south out of Portland to McMinnville and spend two days at the Evergreen Air and Space Museum. There is a Good Sam CG there but we've been able to overnight in the parking lot of the museum (boondock-no hookups). This is where the Spruce Goose is ... and that alone is worth going to see.

Between McMinnvelle and Lincoln City is one of my favorite buffet's and it's inside Spirit Mountain casino (and you can boondock in their parking lot.)

There are others that can give better info on the camping between Lincoln City and Astoria. Lewis & Clark NP ...Ft. Clatsop...

Astoria,OR, ... Astoria Column ... seals sunning on the docks ... drive across the bridge and spend some time on the beach... miles and miles of beach.

From Astoria, take hwy 30 east to Rainier, Oregon and cross the Columbia River via the Lewis & Clark Bridge.... then go out to Interstate 5 and head north toward Seattle until you get to Hwy 12... go east on hwy 12 and take in a bit of Mt. Rainier. You might have time to see both the west and the east side. I think hwy 410 is open already. Snow pack was very low this winter but they are getting a foot of snow in some of the passes right now.

From Mt. Rainier ... go to NORTHWEST TREK. Northwest Trek Wildlife Park is a 723-acre wildlife park located near the town of Eatonville, Washington.

and then head to your ferry.

If your just looking for a place to stay along the way then Columbia Riverfront RV Resort in Woodland Wa. is a nice place to spend the night or a couple of days.
It's just off the freeway (far enough to be quiet) and near shopping.

Let me know if you need anything during your stay here in Bothell.

Scott

On the very north tip of the Oregon Coast: Astoria, Fort Canby/Fort Stevens (Lewis and Clark), oyster beds at the Long Beach (WA) Peninsula, and then cut over at Montesano or head north through Aberdeen to the Hoh Rain Forest. Lots to see in that area.

Mt Rainier, Olympic Pennisula, Victoria BC from Port Angeles

Other than a trip around MtStHelens there is not much between Portland and Seattle except three hours of boring freeway. As an alternative I would take 26 out of PDX and follow US101 north around the Olympics, maybe take a day trip to Victoria from Port Angeles.
