Transportation
The PNT has a fantastic page on getting to and from the Termini.
I used Clallam Transit to get to the Western Terminus. They offer very well priced travel over much of the Olympic Penninsula.
How to Get to Cape Alava from Seattle:
Take the ferry to Bainbridge
Take the Clallam 123 Straightshot bus from Bainbridge Ferry to Port Angeles
Take the Clallam 14 Forks bus to Sappho
This is the last public transportation service to the trailhead.
Hitchhike from Sappho to Ozette
