Bike Trip: Portland to Cascade Locks (with a little gravel and a side of corned beef hash)
Joyce Park stashed this in Bicycling
This is one of the classic Oregon bike touring overnights, featuring ease of access -- you can take public transit to the starting point! -- lovely views, and food at the end. This particular writeup features some dirt (aka gravel) roads for a little changeup to the main highway.
This tour is so Oregon! Everything from the cycling to the views.
