Columbia River Highway, Oregon
As the first scenic drive in the U.S. to earn National Historic Landmark status, the Columbia River Highway was considered an engineering feat when it was built in 1913. The route was designed to emphasize the natural beauty of the area by winding its way to the top of 900-feet cliffs overlooking the river and valley below. Visitors who follow this drive will encounter the fiery hues of fall alongside brilliantly colored wildflowers, dramatic waterfalls, and deep gorges.
Not to be missed: Hiking the 620-foot-tall Multnomah Falls, located along the route about 35 minutes outside of Portland.
