The hike to Wachlella Falls on beautiful Tanner Creek in the Columbia Gorge is one of the most popular hikes in the Oregon side of the Gorge. The hike is roughly one mile in length with approximately 300 feet elevation gain, so it is accessible to almost all. Water from Tanner Creek is so pure that it is chosen to supply the nearby Bonneville Dam Fish Hatchery, a major hatchery for Salmon. The Falls is named for an ancient Chinook Indian village near this site. This image shows the late spring foliage of the forest, the volume of spring runoff, and the delicate wisp of the upper falls tributary. Click on image to enlarge.
