Naches Trail, Historic road in Mount Baker-Snoqualmie National Forest, United States.

The Naches Trail runs from the Naches River in Eastern Washington across Naches Pass in the Cascade Mountains to the Greenwater River in present-day Pierce County. It was never paved; as of 2017 it carries United States Forest Service forest roads popular for off-roading. Since the 1930s the route has been proposed as Washington State Route 168.

The Naches Trail began as a route used by the Yakama and Interior Salish peoples. Lieutenant Robert E. Johnson of the Wilkes Expedition made the first written record of a crossing of Naches Pass in 1841. In 1853, the Longmire Party crossed with wagons, lowering them down the Naches Trail Cliffs with ropes; road construction was then judged infeasible because of dense forest on the west side.

The path served as an important travel route for Yakama and Salish peoples who used it to move through the mountains for generations. Later, settlers relied on it as a crucial way to cross the Cascade Mountains region.

The trail welcomes hikers, mountain bikers, and off-road vehicles, though some sections are set aside only for walkers. Knowing which segments are shared helps you plan and prepare before heading out.

The path remains popular with travelers who want to follow the same mountain crossing that the Longmire Party pioneered. Hikers still discover traces of that 19th-century journey along the way.
