Wahclella Falls is a waterfall along the Columbia River Gorge in Oregon.The Columbia River Highway splits around exit # 40 that leads to the Bonneville Dam. The parking and access area for Wahclella Falls is slightly down the hill and to the right (for eastbound traffic) of the entrance to the dam.Wahclella is at the midpoint of the well maintained trail number 436 loop that forms a 1.8-mile (2.9 km) roundtrip. The United States Forest Service charges a nominal $5US fee for using the trail, although owners of a Northwest Forest Pass or similar recreation pass are exempted from this. 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 grey basalt.
