The new Olallie Trail provides a challenging long distance mountain biking trail experience (also available for hiking & equestrian use), offering several viewpoints of the Snoqualmie Valley and surrounding mountains along the way.  The trail winds through older forest stands, along ridges, and up segments of abandoned logging road and grade-to-trail conversions – gaining approximately 2,700’ elevation.  

Predominantly managed by the Washington State Parks & Recreation Commission—which designed and managed the project in conjunction with Washington State Department of Natural Resources—the trail was constructed by Evergreen Mountain Bike Alliance Trail Crews & the Mountains to Sound Greenway.  

Evergreen trail builders constructed approximately 4.9 miles of the western section of trail (with some volunteer support), while the Mountains to Sound Greenway Trust developed approximately 4.3 miles of the eastern trail segment.  The City of Seattle Cedar River Watershed and the United States Forest Service (the eastern upper elevation 0.5 miles of the trail ends on USFS land near Change Lake) also provided project support.  

The new trail opportunity is the culmination of the Olallie Area Mountain Bike Trail Study, which began in 2002, and resulted in reconnaissance, feasibility studies, and the ultimate vision for a future trail network spanning more than 15,000 acres of public lands. 

We invite you to celebrate the additional 9.2 new trail miles towards this vision, which currently provides a 22+ mile out-and-back (when combined with the Iron Horse Trail), starting from Cedar Falls Trailhead.  Future trail expansion to the east of Olallie Trail will continue to be explored—and potentially implemented—if funding sources are secured.

Funding for this project was provided by a grant awarded to the Washington State Parks & Recreation Commission through the Washington Wildlife & Recreation Program administered by the Recreation & Conservation Office. 

Visitors can most easily access the new trail by parking at Cedar Falls Trailhead and travel the Iron Horse Trail east for two miles to reach the trail entry.  As an alternative, visitors can also leave Homestead Valley Trailhead traveling west along the Iron Horse Trail for three miles to begin the ascent up Olallie Trail.  As the winter season approaches with more consistent precipitation and potential for snow on upper elevation trail segments, we request that visitors carefully consider the weather and trail conditions before embarking on this trail adventure.
