John B. Yeon State Scenic Corridor, State park in Columbia River Gorge, United States.

John B. Yeon State Scenic Corridor is a protected natural area in the Columbia River Gorge featuring interconnected hiking paths to two waterfalls. The main attractions are Elowah Falls, which drops steeply over dark rock walls, and Upper McCord Creek Falls, which cascades through lush vegetation.

The park is named for John B. Yeon, a leading architect and construction manager of the Historic Columbia River Highway, built between 1913 and 1922. Oregon acquired the land through purchases between 1935 and 1956. In 1935 the Civilian Conservation Corps built a bridge over McCord Creek and laid out a footpath.

The park is named for John B. Yeon, a leading architect and construction manager of the Columbia River Highway, built between 1913 and 1922. In 1935 the Civilian Conservation Corps built a bridge over McCord Creek and laid out a footpath, work still followed by today's trail. Entry to the park is free of charge.

The area sits about 35 miles east of Portland and is easily accessed via Interstate 84, with marked parking areas at the trailheads. The hikes are moderate and well-maintained, with clear paths and enough room for visitors throughout the year.

The park was assembled from land the state of Oregon bought between 1935 and 1956. In 1935 the Civilian Conservation Corps built a bridge over McCord Creek and cut the footpath that hikers still follow to Elowah Falls and on to McCord Creek Falls.
