I'm curious what a brisk yet comfortable pace would be for such a trip? The plan is to take 101 to Santa Rosa, then hug the coast all the way up to Astoria, head east to St. Helens, and then zip up to Seattle via 5. I had hoped 3 days would be OK, but I'm starting to think otherwise.
As a separate question, any "must see" attractions in addition to the ones I've already planned? So far I'm hoping to make stops at some coastal parks in California, the Redwoods, Astoria, and Mt. St. Helens. Thanks.
