Wahclella Falls is a waterfall along Tanner Creek, a tributary of the Columbia River, Multnomah County, Oregon, United States.

[clarification needed] Wahclella is at the midpoint of the well maintained trail number 436 loop that forms a 1.8-mile (2.9 km) roundtrip.

[2] The falls are divided into upper and lower segments with a combined height of 350 ft (107 m), the upper section is not completely visible while the fully visible lower segment stands 60 feet (18 m) in height as it thunders out of a narrow gorge carved through dark gray basalt.

[2][3][4] The plunge pool has a picturesque quality due to the surrounding natural walls that form a semi-circular rotunda extending from the falls to the main vantage point.

However, because Tanner Creek is sourced primarily by an underground spring, the flow is never dramatically affected by adverse weather.
