Find out fall foliage timing predictions for the year. Peak foliage times for both Washington and Oregon begin in late October and last until the beginning of November, though color will probably start to peak in mid-October in the highest parts of the Cascades and along the Idaho border.
Try Mount Hood in Oregon as a base for exploring fall color, with the drive along the Hood River Valley as a high point. Mount Hood also has a Harvest Fest one weekend in October, including a train ride to view foliage in neighboring orchards and farmlands.
Take a good drive on Highways 2 and 20 through the Cascade range; allow time for side trips and hikes.
Consider a brief respite in Seattle as a lively starting point for a day trip or a weekend visit.
Visit Wenatchee, Washington, for a quieter location. It is an excellent base for exploring the eastern side of the Cascades.
