Tolt Pipeline Trail

The Tolt Pipeline 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 in an east-west direction along most of its length, with few bends or turns. It has sections of variable difficulty, ranging from flat in the Sammamish River valley to the brief but Mailbox-esque incline of Hollywood Hill (nicknamed “cardiac hill”) in Woodinville.
