Back in the 70s I used to ride my Honda CL350 down to Corvallis to visit friends that were in college there and then ride over to the coast on highway 34. It's still one of the nicest motorcycle roads I know of. This is the way I went to the coast on my way to California. Here is a link to a short (not the whole 65 miles) video of the ride.
