Columbia Plateau State Park Trail
WA · Washtucna / Eastern Washington Corridor
100 SW Main Street
The Columbia Plateau Trail is not a casual afterthought destination—it is a serious eastern Washington corridor with a wonderfully big, rugged personality. Running across the channeled scablands and down toward the Snake River country, the trail serves up immense skies, dry grassland, basalt cuts, and a powerful sense of geographic scale. It feels spare, remote, and confidently unsentimental in the best possible way.
Riding guide
Highlights
Vast, dry, and deeply adventurous, the Columbia Plateau Trail is for riders who want true long-distance character rather than a simple park loop.
Riding
At 130 miles, this trail rewards riders who value forward motion and space. It is less about looping and more about committing to a line through the landscape. Even the improved sections have a frontier-like feeling compared with more curated trail systems.

Trailer parking
Best staged from developed trailheads on the north end or selected access points near Washtucna; trailer logistics are section-dependent and require advance planning.
Horse regulations
Horses are allowed, but preparation is absolutely essential. State Parks warns that resources are scarce, some trestles are closed or undecked, temperatures can exceed 100 degrees, and a flooding washout closure remains in place on part of the trail.
Getting here
Because the trail is long and unevenly developed, the elegant way to approach it is by section. The north portion in Spokane County is more improved and easier to understand, while the southern reaches grow increasingly remote and should be treated like an expedition-style undertaking rather than a casual day ride.
Planning your visit
Choose your segment carefully, bring substantial water and navigation support, and resist the temptation to romanticize the corridor without respecting its seriousness. For strong riders who love real trail scale, though, it is magnificent.
Where to stay
There is no traditional horse-camp convenience built into the trail the way there is at a dedicated equestrian campground. The comfort here comes from smart shuttles, support vehicles, or nearby lodging, not from on-site hospitality. That is part of the trail's appeal.
