The final segment of the East Lake Sammamish Trail is open, completing King County’s portion of the 44-mile paved Locks to Lake Corridor that connects Seattle’s waterfront in Ballard to Eastside cities and the Cascade foothills
The 3.6-mile final link completes the 11-mile trail’s connection to the Burke-Gilman, Sammamish River, Marymoor Connectors, and Issaquah-Preston trails, welcoming people of all ages and abilities to walk, ride, roll, and bike.
At a trail-opening ceremony, County Executive Dow Constantine noted the new lakeside link “allows residents from all across King County to use a safe, healthy, and accessible recreation path” that is 12 feet wide with two of gravel shoulders on each side. Construction crews also installed new culverts for salmon to swim underneath the trail to reach spawning habitat.
The trail follows the old BNSF Railroad along Lake Sammamish’s eastern shoreline. At its southern end in Issaquah, the trail links to Issaquah-Preston Trail. To the north, it connects to the Marymoor Connector Trail at Marymoor Park, which connects to the Sammamish River Trail and Sound Transit’s new Link light-rail stations in Redmond.
King County purchased the East Lake Sammamish corridor in 1997 and opened a gravel-surfaced interim trail in 2006.
The Locks to Lakes Corridor is part of the Leafline Trails network of more than 500 miles of paved, non-motorized trails across King, Pierce, Snohomish, and Kitsap counties.
