I'm planning a loop with a start off of Amtrak in Salem then out to the coast down to Jedediah SP and across to Klamath Falls to catch Amtrak back to Portland and home. Klamath Falls is on a route that requires boxing and does have a baggage stop. I wish there was a stop closer to the coast so I could make use of some of my days in the northern coast section instead of heading so far East to KF.

I rode Tillamook to Newport a number of years ago and I agree with damselfli that Cape Meares is worth it as is the detour off 101 from Neskowin to Otis.
