The Palouse to Cascades State Park Trail
(previously known as the John Wayne Pioneer Trail/Iron Horse State Park) is located within a rail corridor that stretches more than 285 miles across Washington State, following the historic route of the Milwaukee Road from Cedar Falls to the Idaho border. Washington State Parks currently manages approximately 250 miles of trail within this corridor. 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 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.

Starting August-September 2022. Trail closures in Whitman County
The trail is closed along Rock Lake between Rock Lake Road and Hole in the Ground Road in Whitman County due to safety concerns. Starting September 6, the trail will be closed between Malden and Rosalia for improvements. There is no State Parks sanctioned bypass.

(Beverly to the Idaho border)

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.
