Lewis and Clark’s legendary expedition would not have been possible had they not been able to navigate some of North America’s longest rivers. Today, the officially designated water trails of the Lewis and Clark National Historic Trail are an exciting and iconic way for you to explore the region much as Lewis and Clark themselves would have.
Willamette River Confluence is a High Potential Historic Site on the Lewis and Clark National Historic Trail.
Lewis and Clark had twice unknowingly passed the mouth of the Willamette River (called Multnomah by them); first while outbound on November 4, 1805, and again on March 30, 1806.
