From my trip there last spring:
1) Beaux Freres: yes, it is possible to get in. If you are in the biz, very easy (I am not). However, I was there there while somebody ITB was there, so managed to get the tour and tastings with Mike Etzel. Send them an email to inquire.
2) For scenery: If you head down south to Eugene, definitely hit King Estate. Absolutely beautiful.
3) For scenery: In the W Valley, Elk Cove.
Archery Summit is beautiful too, I now understand why they charge so much.

Also, though I did not get to visit them, I heard a lot of wonderful things while there about Domaine Drouhin, Domaine Serene, and Willakenzie.
And not a single place charged a tasting fee. I was there in late April. Very laid back everywhere I went. My favorite question was "what wines do you like to drink when you are not drinking your own." Their favorite question seemed to be "is there anywhere you would like to get a tour that you have not been able to get into?" The folks at Archery Summit and Beaux Freres were particularly friendly and helpful in that respect. But nobody could get me into Ken Wright... I since have acquired a contact out here that may be able to help next time.
Hope this helps a little.
