Oneonta Gorge is a scenic gorge located in the Columbia River Gorge area of the American state of Oregon. The U.S. Forest Service has designated it as a botanical area because of the unique aquatic and woodland plants that grow there. Exposed walls of 25-million-year-old basalt are home to a wide variety of ferns, mosses, hepatics, and lichens, many of which grow only in the Columbia River Gorge. Oneonta Gorge with its 50 species of wildflowers, flowering shrubs and trees has been described as "one of the true dramatic chasms in the state." The Oneonta Gorge Creek Bridge is listed on the National Register of Historic Places.

The Historic Columbia River Highway is an approximately 75-mile-long (121 km) scenic highway in the U.S. state of Oregon between Troutdale and The Dalles, built through the Columbia River Gorge between 1913 and 1922. As the first planned scenic roadway in the United States, it has been recognized in numerous ways, including being listed on the National Register of Historic Places, being designated as a National Historic Landmark by the U.S. Secretary of the Interior, being designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers, and being considered a "destination unto itself" as an All-American Road by the U.S. Secretary of Transportation. The historic roadway was bypassed by the present Columbia River Highway No. 2 from the 1930s to the 1950s, leaving behind the old two-lane road. The road is now mostly owned and maintained by the state through the Oregon Department of Transportation as the Historic Columbia River Highway No. 100 or the Oregon Parks and Recreation Department as the Historic Columbia River Highway State Trail.
