The Palouse to Cascades State Park Trail (previously known as the John Wayne Pioneer Trail/Iron Horse State Park) is a rail trail and linear Washington State Park following the historic route of the Milwaukee Road across Washington State. From the wheat fields of eastern Washington's Palouse region, through central Washington's Channeled Scablands and agricultural Columbia Basin, to the evergreen forests of the Cascade Mountains, this approximately 285 mile long recreational trail showcases Washington's diverse landscape. This website was developed in response to a need for updated MAPS and INFORMATION for trail users and is not affiliated with Washington State Parks.

Detail on the 7 mile Lower Crab Creek detour east of Beverly - Going west to east, leave the trail 4 miles east of Beverly to Lower Crab Crk Rd. Return to the trail directly east of H Street west of Smyrna (This is the detour signed by State Parks). However, we advise continuing on Lower Crab Creek Rd to Smyrna rather than use the trail because of the many goat head thorns (puncture vine) on the trail just west of Smyrna.
