About This Park
Duthie Hill Mountain Bike Park covers 120 acres of evergreen forest on the Sammamish Plateau, managed by King County Parks in partnership with Evergreen Mountain Bike Alliance. A six-mile network of one-way singletrack forms a four-leaf clover around a central clearing with three pump tracks and a practice area with drops. Inside each cloverleaf are downhill-only freeride trails with berms, jumps, and progressive jump lines, while four flowy cross-country trails link into a roughly five-mile loop. The park connects to Grand Ridge and Soaring Eagle parks; a 74-vehicle lot sits off SE Issaquah-Fall City Road.
