The Tolt Pipeline serves as a major connection between Duvall, WA and the Sammamish River. This trail follows a water pipeline right-of-way and is not recommended for all trail go-ers. The majority of traffic on this trail consists of mountain bikers and horseback riders. Due to the many steep grades along the trail, as well as the gravel/dirt surface, bicyclists must be aware of the limitations of their equipment.
Conveniently, the Tolt Pipeline Trail's western terminus in Blyth Park intersects with both the Sammamish River Trail and the Burke-Gilman Trail. It moves eastward on an ungraded surface - making the many hill climbs exhausting. Additionally, the wide cut of the pipeline's right of way ( up to 100 ft) provides little escape from the sun. At West Snoqualmie Valley Road NE, riders can continue via street access to Duvall's portion of the Tolt Pipeline Trail at nearby Duvall Park.
