John B. Yeon Scenic Corridor honors a man who gave generously of his time and professional skills. He was one of the principal architects of the Historic Columbia River Highway (US 30); a major portion of the scenic highway joins I-84 westbound at Yeon State Park.Here is a hiker's paradise with a gentle rising trail that permits access to two of the most beautiful and secluded waterfalls in the Columbia River Gorge: (lower) Elowah Falls and (upper) McCord Creek falls. Elowah Falls is a 289 foot drop over basalt that must be seen to appreciate. The view of the falls and way the tall cliffs jut out at odd angles is nearly disorienting at the bottom of the trail. Most days, the trails are never crowded. The crisp air, easy access and accompanying scenery of this area offer some of the best hiking and viewing opportunities available in the Gorge.
