At the western end of the PTCT at Cedar Falls, the trail connects directly to the Snoqualmie Valley Regional Trail, which runs from Cedar Falls north through North Bend, and further north to Duvall. The Snoqualmie Valley Regional Trail in turn has connections to other King County trails linking to the greater Seattle metropolitan area. (For a more detailed map of the King Co. regional trail system and connections click here).The Snoqualmie Valley Trail (shown above) connects to the west end of the PTCT.In eastern Washington, the Columbia Plateau Trail State Park crosses over the PTCT connecting the Cheney area and TriCities. Currently there is not an easy connection between these two State Park trails but it is possible to scramble from one to the other. An improved connection is beingconsidered as a future developement.
Several years ago the Washington State legislature passed a resolution to support a cross state trail. The Palouse to Cascades Trail is only one part (albeit the longest) of a system of trails that could make up a complete Washington Cross State Trail eventually.In 2019 the national Rails to Trail Conservancy announced the roll out of the Rails to Trails Conservancy's Great American Rail Trail . The Palouse to Cascades Trail is a "gateway trail" in the Great American Rail Trail. This trail system is still far from complete, but someday the Great American Rail Trail sections currently in development may connect across Washington as below.
The Milwaukee Road corridor continues east through Idaho on private land and intersects with Idaho's Trail of the Coeur d'Alenes only a few miles from the end of the PTCT at the Washington-Idaho border. Remnants of the old Milwaukee Road can be found in Idaho and Montana as well. There are efforts in both Idaho and Montana to develop trails that link sections of this corridor with existing trails. Someday a trail network could connect the Pacific Coast with the Rocky Mountain region, an epic NorthWest system of trails!
