This hike was done less than a week before the Eagle Creek fire. We don’t know how bad this trail has been damaged. Hopefully the damage was minimal and we’ll be able to see all three of the waterfalls on this hike again soon!
Directions: Take I-84 East to the Ainsworth State Park (exit 35) and follow the Old Highway left towards Horsetail Falls.
We decided to do this hike in the opposite direction that we went the last time we visited, which was a couple years ago. To see that post click here.
Park in the Horsetail Falls parking lot and take the trail just to the left of the waterfall. You’ll be heading up long switchbacks that take you up above Horsetail Falls. The trail levels out a bit as you round a corner and start hearing Ponytail Falls. The waterfall itself pours out of a crack in the basalt shelf and dumps into a small pool below. The trail takes you behind the waterfall and continues on the other side.
Not far after the waterfall you’ll pass a slide area and come to a side trail that takes you to a great view of the Columbia River and nice views of the Gorge to the east. Back on the main trail it continues to stay pretty level for a bit and then you hit a few more switchbacks as you head down into the Oneonta Gorge area. You’ll cross a bridge and get a nice view of Middle Oneonta Falls and the Gorge itself. If you’re here on a warm day you’ll probably hear the crowds of people at Lower Oneonta falls below.
After crossing the bridge the trail heads uphill to a trail junction. Go right here and the trail switches from being level to heading uphill, but nothing too steep. There is another small slide area and you’ll pass another side trail that takes you to a viewpoint. Soon the trail starts heading downhill as you make your way down to the old highway.
Go right on the should of the highway (be cautious, there isn’t a lot of room here) and pass Oneonta Gorge and go through the Oneonta tunnel, about a quarter of a mile later you’ll be back at Horsetail Falls.
Distance: 3.5 miles (easy)
Elevation: 650 feet (moderate)
Pet Friendly: Yes
Good For: This depends on how comfortable you are with hiking. There are a decent amount of switchbacks on this trail and places you could fall (there was a death on this trail last year). You’ll also be walking along the old highway for a short distance. Be cautious and make sure you’re surefooted and you should be fine.
Parking Fee: None
Warnings: Falling and walking along a narrow road.
