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.
Beginning of trail construction along the north segment is anticipated for summer 2018.

The Green to Cedar Rivers Trail, much like all of our Regional Trails System trails, is a work in progress requiring constant management and upkeep. We always welcome constructive suggestion about trail maintenance, or safety from our users. Be sure to let us know if you see something on the trail that you think we can improve.
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.
Project Information by Segment:
Location: 3 miles beginning at the Cedar River Trail to SE Kent Kangley Road
Construction update: Connecting the Cedar River and Green River in south King County, the full, 11-mile trail is set to be developed as a paved, shared-use regional trail to accommodate a variety of users. While the project experienced delays over the past year, King County Parks is moving forward with this important trail project and is currently selecting a design team for the north segment of the trail. Parks anticipates the design process to start at the beginning of 2017.
The design team for the north segment of the Green to Cedar Rivers Trail has been chosen and is awaiting initial community outreach.
