This Oregon waterfall plunges 226 feet, and there’s no pool at the bottom to catch it
Most Oregon waterfalls end in a pool you can wade into. Proxy Falls skips that step entirely — the water drops 226 feet down a basalt cliff, hits the ground, and just disappears.
No creek flows out the other side. It sinks straight into porous lava rock and keeps moving underground, which is part of why this loop in the Three Sisters Wilderness pulls hikers in from both Eugene and Bend.

Where the water actually goes
The valley here was carved by glaciers, then partly filled in by lava from nearby cinder cones. That lava rock is porous enough to swallow an entire waterfall, so instead of pooling at the base, the water just sinks into the ground and keeps flowing underground.
Upper Proxy Falls, a short walk from the main falls, does the exact same disappearing act. Stand at either one and you’ll notice there’s no outlet, no stream leading away — just rock.

The hike itself
Proxy Falls Loop Trail is 1.6 miles round trip with about 164 feet of elevation gain, rated moderate on AllTrails — and that rating is about the scrambling near the falls, not the distance. Plan on 30 to 60 minutes if you’re just doing the loop.
The first stretch crosses an old lava field with zero tree cover, then drops into mossy old-growth forest that feels like a completely different hike. We’ve done this loop more times than we can count, and the shift from bare lava rock to dripping green forest never gets old.
Getting close to either waterfall means picking your way over logs and slick rock with no official trail. Sturdy shoes with real traction are worth it, and it’s smart to skip the scramble if the rock looks wet and you’re not steady on your feet.
Getting there, and what it’ll cost you
The trailhead sits nine miles east of McKenzie Bridge on Highway 242, and getting there depends entirely on that road being open. OR 242 only runs June through October — it’s closed for the winter every year — and it reopened for the 2026 season on June 15, per the Oregon Department of Transportation.
There’s a vault toilet and picnic tables at the trailhead, but no potable water, so pack your own. Parking runs $5 per vehicle, and a Northwest Forest Pass covers it too.
We’ve got a full trail guide to Proxy Falls if you want turn-by-turn detail on the loop, and if you’re coming from the east side, Sisters makes an easy staging point before the drive over the pass.
Lower Proxy or Upper Proxy — pick a favorite if you can. We still can’t, and we’ve been going for years.
Trip tips: grab a rental car to get out here, since there’s no other way in, and lock in a hotel in Sisters or Bend before the good rooms are gone if you’re making a weekend of it.
