X2 Ford Idaho and going to see/hike around Crater Lake.
Grants Pass isn't too far away and you can catch a ride down the Rouge River on a jet boat. This section of the Rouge River was where "Rooster Cogburn and The Lady" (John Wayne and Katharine Hepburn) was shot. I think you can also catch the jet boats going up river from Gold Beach off Hwy. 101.
DW and I were just talking about our honeymoon through Oregon and she reminded me of the gorgeous drive we took through the McKenzie River Pass. I'm pretty sure we went north out of Bend and caught 242 out of Sisters through the pass to Eugene. This was a long time ago and I'm not sure if that road is OK for an RV, but I do recall we loved the scenery.
In my motorcycle riding days my dad and I loved going up 101; as others have said it's hard to beat a drive up the Oregon coast. Chris and Cherie from Technomadia
have a whole bunch of posts of their tour of the lighthouses on the Oregon coast.
