Duthie Hill Park

Location: Issaquah, WA
Chapter: Statewide
New Mileage: 0.25 miles
Status: In Progress
Projected Completion: Summer 2024

Evergreen’s biggest and highest profile mountain bike park project, King County’s 130 acre Duthie Hill Park is located at 27101 SE Duthie Hill Rd., on the Sammamish Plateau, 30 minutes from downtown Seattle. It includes six miles of cross country bike trail, two miles of free-ride trail with jumps and built features, a central clearing with a shelter, a kids’ biking area, opportunities for skill building, and more. Trail users range from tots on push bikes and first-time riders to expert mountain bikers.

The park was built through a partnership between the non-profit Evergreen Mountain Bike Alliance and King County. It officially opened for mountain biking after the completion of Phase 1 construction in 2010, and has since seen approximately 100,000 rider visits per year. Phase 2 was completed in May of 2012.

Funding for Duthie comes from a combination of grants and overwhelming community support including $225,000 of private donations and thousands of hours of volunteer labor. The Washington State Recreation and Conservation Office also funded a portion of the initial construction and also helped fund the much-needed parking lot that was completed in November 2013.

In 2018, Evergreen will add a new access trail, including a modified blue trail conversion to enable access for people with disabilities and rebuild all three pump tracks in the park.

In 2021, Evergreen is primarily working on maintaining existing trails and making sure the park stays in great condition for the throusands of annual visitors.

In 2022-24, we will be building new access trails so you won't have to ride on the road! There will be a new descent trail on the northside of the clearing drops down into Ryan's line (about 200 ft long). We will be widening Bootcampfor the use of adaptive mountain bikes, and re-working many of the jump lines. We will be hosting weekly work parties all year, so be sure to check out the events schedule and we'll see you out there!

Duthie’s trail system is connected to trails on more than 2,000 acres of public open space, including King County’s Mitchell Hill Forest, and Grand Ridge and Preston Ridge parks.
