The Tualatin River has its headwaters in Oregon's north Coast Range and flows through Washington County, one of Oregon's fastest growing and most populated counties.
Safe put-ins and take-outs are in Hillsboro, Tigard, Tualatin and Lake Oswego. Its confluence with the Willamette River is in old West Linn, about a mile upstream from the Oregon City/Willamette Falls. The park at the mouth of the river has an excellent launch area, however, a rock garden in the first mile of the Tualatin makes an upstream trip impossible even for the hardiest of paddlers.
