The Springwater Corridor is the major southeast segment of the 40-Mile Loop which was inspired by the 1903 Olmsted plan of a parkway and boulevard loop to connect park sites. The eventual developed trail will be over 21 miles long.
For the most part, the trail is well separated from the public road. The route is a scenic one, encompassing wetlands, buttes, agricultural fields and pastures, residential and industrial neighborhoods. Close to Johnson Creek, one of the last free-flowing streams in Portland's urban area, the trail criss-crosses the stream on its course to the Willamette River.
