Start at the Multnomah Falls Trailhead. Hike to the top of Multnomah Falls and continue up Multnomah Creek. Turn left at the Franklin Ridge junction, and follow the trail through a variety of forest covers and seasonal wildflowers to the junction to Oneonta Gorge. After descending into Oneonta Gorge, follow Oneonta Creek past Triple Falls and to a junction. Here, you can decide to complete the hike one-way by taking the route to Horsetail Falls and Ponytail Falls, or continue on Gorge Trail #400 back to Multnomah Falls.
Lumber baron and philanthropist Simon Benson donated the land that the falls sit upon and funded the construction of the iconic Benson Bridge in front of Multnomah Falls, the tallest waterfall in Oregon and the Columbia Gorge's most recognizable natural landmark. Benson's generosity later helped citizens work with timber companies in the 1940s and 1950s to secure protection of some of the Gorge's most iconic waterfalls.
