Typically one can expect the Willamette Valley peak color change to happen during the third week in October.
The higher you go in the Cascade Mountains the earlier the color change. Road passes often peak 10 days to two weeks earlier than the lower elevations.
The earliest fall color display happens in the Wallowa Mountains and northeast region of Oregon, peaking the first part of October.
I found this blog, Oregon Fall Foliage Report, and from Labor Day through November, their goal will be to let you know where to find the best and brightest colors throughout the state. Visit or call the Fall Foliage Hotline at 800.547.5445.
Begin planning your Fall Foliage Tour, first by choosing a region, then by calling an Oregon Bed and Breakfast Guild inn and asking when the peak near them will occur. We may not hit it right on but since we live and play in our regions we have a pretty good idea what's happening around us.
The Oregon Bed and Breakfast Guild has 90 quality assured inns throughout Oregon.
From the coast to the Willamette Valley. From the Cascades to the high altitudes of Eastern Oregon you'll enjoy the crisp cool days of fall and come home to the warmth of a unique Oregon Bed and Breakfast.
