· Washington State/lower British Columbia: Late October, with a few patches possible in mid-October.
· Oregon: Late October, but best will likely be the first week of November
· Northern California: Nothing for the coast, but in the north eastern bit of California, expect to see color come in around the third week in October, through the first week of November.
· Rocky Mountains: Early October, with the chance of late September depending on your elevation
CN Traveler's destination guide from 2011 still holds up, but remember that the Northwest is home to much flora that doesn't turn color at all, so fall foliage isn't as plentiful as in the Northeast, but it's worth a weekend away.
