The Tolt Pipeline Trail serves as a major connection between Duvall, Washington, and the Sammamish River in Bothell. The trail follows a water pipeline right-of-way and is not recommended for all trail users. The majority of traffic consists of mountain bikers and horseback riders. Due to the many steep grades along the trail, as well as the gravel and dirt surface, bicyclists must be aware of the limitations of their equipment.
Conveniently, the Tolt Pipeline Trail's western terminus in Blyth Park ends very close to both the Sammamish River Trail
and the Burke-Gilman Trail
. It moves eastward on an ungraded surface, making the many hill climbs an intense workout. Additionally, the wide cut of the pipeline's right of way (up to 100 feet) 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. Just to the west of the park, the trail directly connects to the Snoqualmie Valley Trail
Parking for the Tolt Pipeline Trail can be found at the Northshore Athletic Fields on NE 145th Street/State Route 202 in Woodinville. Alternatively, park at the Kathryn Taylor Equestrian Park on 232nd Avenue NE in Redmond.
