Visual Characteristics

The trail is predominantly flat, with a paved surface measuring approximately 8 feet in width. It is bordered by mature deciduous trees, primarily cottonwoods and alders, providing significant canopy cover. The Cowlitz River is visible along the western edge of the trail, with water color varying from brown to grey depending on recent rainfall and sediment load.

Historical & Ecological Origin

The trail was constructed in the early 2000s as part of Longview's urban trail system development. Its purpose is to provide recreational access to the Cowlitz River corridor.
