Route and access notes

A primarily gravel-packed Columbia County trail connecting Scappoose and Vernonia, Oregon, along a former logging corridor through rural forest and foothill landscapes.

Planning this route

The refreshed connected geometry is 35.1 km, matching the mapped 22-mile line and the county's approximately 23-to-25-mile description as access and endpoint connections develop. It links toward the Banks-Vernonia trail network but is a separate named route.

Access and source limitations

Columbia County manages the corridor for cyclists, pedestrians and equestrians and prohibits unauthorized motor vehicles. Short road and unknown-surface connections in the mapped line require local-sign and traffic awareness; conditions can be rougher than a paved rail trail.
