The Northwest’s biggest waterfall by volume sits 26 miles from Portland, and the best views are from the road

The biggest waterfall by volume in the Northwest is wedged between a highway, a dam and a former paper mill, and most people drive right past it. That’s Willamette Falls, a roughly 40-foot curtain of river stretching about 1,500 feet across, just 26 miles upriver from Portland.

It doesn’t have a trailhead or a gift shop. What it has is raw scale, and a few spots where you can see it for free.

Where to see Willamette Falls without a tour

Your best bet is the signed viewpoint on Highway 99E in Oregon City. Cross the Oregon City Bridge, turn right onto 99E, and it’s about 1.2 miles to the pullout. My pick: start here, because the falls fill the whole frame.

Heading north on I-205? There’s a scenic wayside at Exit 7 with a view down to the falls, but it’s northbound traffic only. The Oregon City Bridge also gives you a distant look, which works better as a quick photo stop than a destination.

Why you can’t just walk down to it

Industry kept people away from the falls for well over a century. Right now there’s no public path to the base, and the walkway has been open only through private guided tours. It’s one of those places where the best seat in the house is still behind a gate.

The falls matter far beyond the scenery. Salmon runs drew tribes here to fish and trade long before Oregon City existed, and tribes still harvest ceremonial salmon and lamprey today. Pretty humbling, right?

A big piece of Oregon history in one spot

The Willamette Falls Locks opened in 1873 so boats could climb past the drop, and they ran until 2011. In 1889, a power line from here to Portland became the first long-distance transmission of electricity in the U.S. Not bad for one riverbank.

Paper mills operated at the falls from 1866 until the last one, Blue Heron, closed in 2011. Today the Willamette Falls Trust calls the chance to secure public access a once-in-a-generation opportunity.

What’s coming next

Planned features include walkways, viewing structures and spaces for ceremonies, with direct river access. No opening date has been announced, so treat a riverwalk as a “someday” rather than a “this weekend.” That makes a visit now feel a little like seeing something right before it opens up.

If you’re already out chasing waterfalls near Portland, this one is a fast add-on. Pair it with the rest of the 17 waterfalls near Portland for a day that goes from classic Gorge drops to a river-wide wall of water.

Will you stop for the view, or are you holding out for the day the riverwalk opens?

Trip tips: grab a rental car to get out here, or lock in your hotel before the good rooms are gone.
