Wahclella Falls, Waterfall in Columbia River Gorge, Oregon, US

Wahclella Falls drops about 350 feet (107 m) in two segments on Tanner Creek, a Columbia River tributary in Multnomah County, Oregon. The fully visible lower tier falls 60 feet (18 m) out of a narrow gorge cut through dark gray basalt. Its plunge pool sits in a semicircular rock rotunda between the falls and the main vantage point on trail 436.

Wahclella Falls was named in 1915 by the Mazama mountaineering club after a nearby Native American village. The falls lie on Tanner Creek, a Columbia River tributary, just above its mouth in the Columbia River Gorge. The trailhead sits near Exit 40, the Bonneville Dam exit off the Columbia River Highway.

The Mazama mountaineering club named the falls in 1915 after a nearby Native American village; the sources do not record the village's language or the meaning of the word. Hikers today pass the name on trail signs along the 1.8-mile loop.

The hike starts from the Bonneville Dam exit on Interstate 84 and is short enough for most people to complete in half a day. Parking is available at the starting point, and the trail itself is well-marked and maintained throughout.

The falls sit at the midpoint of trail 436, a 1.8-mile loop, and the plunge pool is enclosed by natural walls forming a semi-circular rotunda that runs from the falls to the main vantage point. Because Tanner Creek is fed mainly by an underground spring, its flow is never greatly affected by bad weather.
