The Oneonta Gorge is in the Columbia River Gorge with a unique set of aquatic and woodland plants.
This popular adventure up Oneonta Gorge is extremely unique. You can visit Oneonta Gorge any time of year, but you dare only hike up it when the water is very low, because UNLIKE ANY OTHER HIKE ON THIS WEBSITE, you must actually walk up the river, there is no trail.... the river is the trail.
From I-84, take Exit #35/Ainsworth and head west on the Historic Columbia River Highway for approximately 2 miles. Just east of the Oneonta Tunnel on your left/south is the Oneonta Gorge. Parking is limited.
