The Willamette Valley AVA encompasses the drainage basin of the Willamette River. It stretches from the Columbia River in the north to just south of Eugene in the south, where the Willamette Valley ends; and from the Oregon Coast Range in the west to the Cascade Mountains in the east. At 5,360 square miles (13,900 km2), it is the largest AVA in the state, and contains most of the state’s wineries.
