Through the Slot: Exploring Oneonta Gorge’s Wet, Wild Short Hike
A narrow, wet slot canyon that rewards the curious — get your feet wet and your camera ready.
By the time you spot the notch in the basalt, the air changes: the sun softens behind a ribbon of ferns, and a cool steam of spray carries up the gorge. Oneonta Gorge announces itself not with a wide-open vista but with a sudden intimacy — a narrow, green-walled corridor where water has bored a living seam into ancient lava. You step down into ankle-deep water and realize the hike will be measured in splashes as much as in miles.
Trail Wisdom
Start early
Parking along the Historic Columbia River Highway fills quickly—arrive before 9 a.m. to secure a spot and avoid crowds.
Expect stream crossings
Plan on multiple creek wades; neoprene socks or waterproof boots and a trekking pole make them safe and comfortable.
Check trail closures
Access to the gorge can be restricted for safety or restoration—confirm current conditions with Oregon State Parks.
Protect fragile habitat
Avoid stepping on moss-covered ledges and pack out all trash to preserve the gorge’s delicate plant life.
Local Knowledge
Hidden Gems
- •Oneonta Tunnel viewpoint — the old highway cut gives a different vantage on the gorge
- •Short roadside pullouts nearby have intimate fern coves and small cascades often missed by tour buses
Wildlife
American dipper (river bird often seen near waterfalls), Black-tailed deer
Conservation Note
The canyon supports delicate mosses and rare lichens; stay on durable surfaces, avoid trampling vegetation, and observe posted closures to limit erosion and protect habitat.
Oneonta sits along the Historic Columbia River Highway corridor, the first scenic highway in the U.S., designed in the early 1900s to connect Portlanders with the Gorge’s waterfalls.
Seasonal Guide
spring
Best for: Peak waterfall flows, Lush moss and ferns, Cool, dramatic light
Challenges: Cold creek water, Slippery rocks, Increased trail closures for safety
Spring brings the most dramatic flows and the Gorge at peak green; footwear and caution are non-negotiable.
summer
Best for: Milder creek crossings, Warmer weather, Longer daylight
Challenges: Lower waterfall flows, Higher visitor numbers, Sun exposure on road stops
Late summer offers easier crossings and clearer footing, though the falls are less powerful.
fall
Best for: Autumn color on ridge trees, Crisp air, Fewer crowds
Challenges: Unpredictable rain, Quickly cooling creek water, Shorter days
Fall balances quieter trails with cooler conditions—dress in layers and be ready for rain.
winter
Best for: Moody, storm-swept scenes, High water volumes, Photography of dramatic skies
Challenges: Icy footing, Very cold water, Possible access restrictions
Winter makes Oneonta dramatic but more hazardous; only go if you have appropriate gear and experience.

Common Questions
How long is the Oneonta Gorge hike?

Do I need special permits to visit?
No special permit is usually required for day visits, but access can be restricted for safety or restoration—check Oregon State Parks updates before you go.
Will I get wet on the trail?
Yes; the trail requires multiple creek crossings and often involves wading through cold water, so plan on getting at least your feet wet.
Is Oneonta Gorge suitable for children?
Older children who are comfortable with slippery rocks and water crossings can do the hike; younger children may struggle with the logjam and balance required.
Can I combine Oneonta with other waterfalls in a day?
Yes — many visitors combine Oneonta with stops like Multnomah Falls using tours such as the Half Day Columbia River Gorge Waterfalls Tour or full-day options for a broader itinerary.
Are there restroom or food facilities at the trailhead?

Did You Know
The Columbia River Gorge’s steep-walled canyons, including Oneonta, were dramatically deepened by the Missoula Floods at the end of the last Ice Age — giant, repeated floods that shaped much of the region’s topography.
