Personally, I would go north on I5 and shoot of to hit Crater Lake, staying at Valley of the Rogue State Park, unless you can get into Crater Lake. Maybe a trip over to Bend. Definitely a couple days in Portland and Seattle. Then head back south on the 101 in Washington. We love staying at Fort Stevens State Park in Astoria. There are a number of other really great Oregon State Parks on the beach, like Harris Beach State Park in the south. I've always wanted to stay at Beachside State Park in Waldport, but haven't had the opportunity. They have a few spots where you can literally back your rig up to a perfect view of the ocean 30 ft. away. Then hit the Redwoods for a few days. If you head south on the coast, you will get the benefit of a little better view, but if being that close to a cliff makes you nervous, reverse the order.
