Willamette Falls is the second largest waterfall by volume in the United States, featuring a 42-foot-high and 1,500-foot-wide horseshoe-shaped cascade. Located on the Willamette River, it is a significant historical and cultural site, marking the end of the Oregon Trail and a major industrial hub. The falls are surrounded by viewpoints along Highway 99E and Interstate 205, offering scenic views of the surrounding bluffs. Features include the oldest continuously operating multi-lift lock and canal system in the U.S. and plans for a riverwalk to enhance public access.
