Bike riders, walkers, joggers, and others enjoy traveling the 11.8 miles of paved surface. This trail is a joint project between Snohomish County, the cities of Everett and Lynnwood, and Public Utility District No.1 of Snohomish County. While most of the trail is separated from motorized traffic, there are several places where the trail is a designated bike route on the road shoulder. Follow the Interurban logo signs along the route. Horses are allowed on the Snohomish County link of the Interurban; however, horses are not allowed on the segments of the trail maintained and operated by the cities of Lynnwood and Everett. Use of horses on the trail is not practiced very often because of the asphalt surfacing, as well as the several breaks between runs with crossing traffic to get to the next leg.
