Oneonta Gorge

Oneonta Gorge is a narrow slot canyon on Oneonta Creek beside the Historic Columbia River Highway in Oregon’s Columbia River Gorge. Its best-known destination is Lower Oneonta Falls, a roughly 100-foot plunge into a pool near the upper end of the canyon. The tight walls carry bright lichen, giving the short gorge its vivid green look. Before the closure, reaching the falls meant following the creek bed for about 0.3 mile; that short distance hid a rough route through rocks, water and a large logjam. The Forest Service currently closes the area inside the gorge walls, from Highway 30 to Horsetail Falls, after the 2017 Eagle Creek Fire. It has published no reopening date. Do not enter or wade up the creek.

The closure is the first thing to plan around, because Oneonta became famous for the walk itself. This was not a paved waterfall overlook or an ordinary trail to a viewing platform. The historic route descended stairs from the highway crossing into the creek, then used the watercourse as the path. Pools could require swimming or chest-high wading, and conditions shifted with water levels and logjams. Lower Oneonta Falls waited about a third of a mile upstream. Those details explain both the appeal and the commitment of the old outing, but they are historical route details only; they are not instructions for reaching the falls now. Do not look for an alternate approach along the creek.

Oneonta’s other story belongs to the highway. The gorge was one of the original “beauty spots” chosen for the Columbia River Highway, whose first alignment and bridge here date to 1914–15. The timber-lined Oneonta Tunnel runs 125 feet through a 200-foot basalt outcrop beside the creek. A new bridge and bypass road were built in 1948, leaving the old passage out of the driving route. It reopened in 2009; the Eagle Creek Fire later burned through the tunnel and destroyed its timber lining. The creek, canyon, highway and tunnel form one layered landmark: a natural slot that helped shape a celebrated road, then a place whose access and structures were altered by fire.

Keep Oneonta Trail #424 separate in your plans: it is a different Forest Service trail, not a workaround into the closed gorge. For a photo, the historic tunnel and stone parapets work together; the rails show the opening’s scale. A current legal place to stop or walk for that view has not been confirmed, so do not treat the image or map pin as access guidance. The photograph shows the tunnel entrance, not the lichen-lined creek corridor or Lower Oneonta Falls. Check the current closure before traveling; until the Forest Service changes it, count Oneonta as a landmark to understand through the highway’s history, not a creek-bed hike to attempt.
