I just completed the London to Paris ride three weeks ago. We covered a lot of beautiful farm country in Normandy, France. I'd love to ride there again.
Ditto to OP, generally anywhere in Europe.. Though I have had an urge to simply pack up and head to Italy for quite some time. If only it were that easy.
I don't know about Western Europe, not that exotic. I'd like to try Africa or this, shot in Tenerife, coolest video I've ever seen. If that doesn't make you want to ride nothing will.
