Tucked away in the iconic Columbia Gorge Recreation Area of Oregon, Oneonta Falls is not just a swimming hole—it’s a portal to a world of natural wonder. Located an easy drive from Portland and Gresham, this breathtaking oasis is fed by the serene waters of Oneonta Creek, which carve their way through a dramatic gorge adorned with moss-covered basalt walls. The gorge itself is a botanical treasure trove, housing an array of rare aquatic plants, ferns, and lichens unique to the Columbia River Gorge. These 25-million-year-old basalt formations serve as a living gallery of geological history, captivating visitors with their intricate textures and towering presence.

Best Time to Visit Oneonta Falls for Swimming and Hiking

Seasonal variations play a crucial role in the experience at Oneonta Falls. Spring brings an explosion of wildflowers, painting the gorge in vibrant hues, while summer offers optimal swimming conditions. Fall unveils a tapestry of golden foliage, creating a picturesque backdrop for photographers, and winter transforms the area into a quiet, frosty haven for solitude seekers. Each season offers its own charm, but late summer and early fall are generally regarded as the best times to visit for swimming and hiking due to milder water flow and comfortable temperatures.

How to Get to Oneonta Falls from Portland and Gresham

Accessibility to Oneonta Falls involves a short drive followed by a moderately challenging hike. From Portland, take I-84 East to the Ainsworth State Park Exit 35, then turn west onto the Historic Columbia River Highway and continue for 1.5 miles to the Horsetail Falls Trailhead parking lot.

Be prepared for wading and scrambling as the trail merges with the creek.

What to Expect on the Oneonta Falls Trail
