Tolt pipeline trail, Multi-use trail in Washington, United States.

The Tolt Pipeline Trail is a 100-foot-wide (30 m) unpaved route for equestrians, pedestrians and mountain bikers. It runs 12 miles (19 km) along the Tolt pipeline right-of-way from Bothell, Washington, to the Snoqualmie Valley Regional Trail near Duvall.

The trail was created as a corridor over a water pipeline that has transported water from mountain sources to valley cities for many decades. The infrastructure enabled suburban growth while today serving as a recreational path for the community.

The trail draws mountain bikers, equestrians, dog walkers, and hikers who form an active community of outdoor lovers in the region. You regularly encounter people moving at their own pace, creating a social rhythm along the path.

The trail is accessible from multiple points where parking is available, making it easy to start from different locations. Wear sturdy footwear and prepare for varying elevation changes, especially in certain sections that climb steeply.
