- Tolt Pipeline Trail (wta.org)
The Tolt pipeline provides water to the City of Seattle and runs from the Tolt Reservoir in the Cascades to the Lake Forest Park Reservoir. The pipeline passes though Seattle’s northern Eastside suburbs, and the pipeline’s 100-foot-wide right-of-way has been converted in part to a non-paved, multi-use trail for equestrians, dog walkers, mountain bikers, joggers, and hikers. The trail runs 12 miles from Duvall to Bothell.
