Mountain Biking Cheasty Greenspace Trails

The Cheasty Greenspace trail system sits just four miles from downtown Seattle, offering urban riders a quick dirt fix without the drive. The newest addition, the one-mile Trillium Trail, forms the North Loop alongside the 0.4-mile multi-use Ninebark trail and a short pedestrian connector. Trillium is a mountain bike-only, one-way trail that flows through dense forest. According to Matt Blossom, one of Evergreen's lead trail builders on the project, "The new Cheasty North Loop expands on the success of the South Loop, offering a longer ride with flowy lines and playful features that keep things interesting under a canopy of maples."

The North Loop connects seamlessly with the existing South Loop, which includes the Red Cedar, Cottonwood, and Snowberry trails that opened in 2022. Red Cedar and Cottonwood are both mountain bike-only, downhill-only trails. As Blossom explains, "The multi-use Ninebark trail was designed to make the whole Cheasty network more accessible. It connects the South Loop to the broader neighborhood—from Viewpoint Park up to Cheasty Boulevard—so riders and walkers can flow through the system without ever touching pavement."

This isn't a technical test piece or a massive jump line, but as Blossom puts it, "This project adds a much-needed boost for inner-city riders looking for quick, quality dirt. Cheasty is an awesome place to spin some laps and then hit one of the many nearby cafés, breweries, or food spots on Beacon Hill." The combination of purpose-built singletrack, smart trail design, and true urban proximity makes Cheasty a unique addition to the Seattle mountain bike scene.
