The Willamette Valley is a fertile mix of urban, rural, and wild stretching from Portland at the north to Cottage Grove at the south. It is bordered by the Cascade Range to the east and the Coast Range to the west. The Calapooya Mountains border it to the south and the mighty Columbia River runs along the north. Running north and south, Interstate 5 connects communities throughout the valley. In the mid-1800s the Willamette Valley was the destination of emigrants on the Oregon Trail, and today is home to about two-thirds of the state's population. The Willamette Valley is 150 miles long and up to 60 miles wide, which makes it Oregon's largest wine-growing region.
