Green to Cedar Rivers Trail

The Green to Cedar Rivers Trail is currently in design. Once completed it will be a north-south connection for cyclists, pedestrians and equestrians, weaving through the best of an exceptional landscape connecting south King County communities to rivers, lakes, creeks, and natural areas. This 11-mile trail will improve a section of existing soft-surface trail to a full standard shared-use trail and eventually extend it, connecting the Cedar River Trail to Flaming Geyser State Park on the Green River.

Trail History

A trail from Seattle to Flaming Geyser State Park

The vision for the trail was originally proposed in the 1992 King County Regional Trails Plan as the “Maple Valley-Flaming Geyser Trail”. The County has been in discussion about the trail vision with the cities of Black Diamond, Maple Valley, and Covington, as they are primary stakeholders within the corridor. In 2012, King County conducted a feasibility study for the trail corridor that identified key opportunities and constraints for future development. Funding for the preliminary design of the entire corridor and construction of the North Segment was proposed as part of the 2014-2019 King County Parks, Trails, and Open Space Replacement Levy.

Why is King County developing the Green to Cedar River Trail?

The Green to Cedar River Trail is part of a larger vision of mobility and access to all residents of King County. Not only does our Regional Trails System provide a connection between locations, it also connects people to healthy living, recreational opportunities, mental health, stress reduction and much, much more.

A trail for the community

By 2018, design of the 3.3-mile north segment portion of the paved trail is expected to be approved, and in the years following, the southern portion of the trail along Black Diamond to Flaming Geyser State Park is anticipated.

Design and construction of each portion will continue to adhere to the agreements made during the early planning phase to provide a safe, multi-use regional trail for bicyclists, pedestrians, joggers, skaters, strollers, wheelchairs, and users of all ages and abilities.
