I sent for this handy booklet and found it to be an excellent resource for scenic byways in Oregon. For each byway, it includes a comprehensive description, a map, photos, and information on nearby attractions. Not only does it describe byways listed with National Scenic Byways, but also other Oregon tour routes. A nice addition is a handy little state map with the byways color coded.
You can get this driving guide by visiting Travel Oregon. Oh, I forgot to mention, this booklet, other travel guides, and Oregon road map are FREE!
If you plan on riding in Oregon, make room for this guide in your saddlebags.
