The John Wayne Trail (also known as the John Wayne Pioneer Trail) has several sections. The section between North Bend, Washington, and Beverly, Washington, is the Iron Horse Trail, managed as Iron Horse State Park; this section is pretty much complete (with one or two short road detours to get around missing or unsafe railroad bridges). Part of this section is also part of the Mountains to Sound Greenway. At Beverly, the trail crosses the Columbia River on an old railroad bridge and runs to Warden, Washington, managed by the Department of Natural Resources; this section has a few detours on roads to get around unfinished sections. From Warden to Tekoa, Washington, the trail is again managed as a state park, and is under construction. Since there is a significant mountain range in the middle of the state, there is some climbing involved, although it is a converted railroad so the grade is not steep. Also note that the trail is at least partly covered in snow in the winter (a section near Snoqualamie Pass is groomed as a cross-country ski trail in the winter).
On the western end, you can connect this trail with the Snoqualamie Valley and Tolt River Trails.
