Trail Description

The East Lake Sammamish Trail follows a historic railroad route along the eastern shore of Lake Sammamish within the cities of Redmond, Sammamish and Issaquah. Part of the “Locks to Lakes Corridor,” the trail is approximately 11 miles long and follows an off-road corridor along the lake and through lakeside communities. The existing “interim” soft-surface trail provides excellent views of the lake and Cascade foothills, and is popular with off-road bicyclists, joggers, walkers and other users. The ELST will be upgraded in phases to become a fully paved facility with soft-surface shoulders.

What's Happening on the Trail?

Sammamish Half Marathon

Sunday, September 18, 2016 - This year's Cycle the WAVE (Women Against Violence Everywhere) race was held on the East Lake Sammamish Trail. Cycle the WAVE, is a fully supported, non-competitive, deluxe all-women's cycling event in its 9th year. It is a bike event for women of all ages and fitness levels to experience camaraderie, increase awareness of domestic violence through visibility and to raise funds for domestic violence programs across Washington State.

Thanks to riders and supporters like you; the event has donated almost $700,000 to domestic violence related agencies and non-profits across Washington State since 2008!


Trail History

A trail 45 years in the making – For over 100 years, the East Lake Sammamish corridor existed as a railroad, used to move goods through the area. The King County Urban Trails Plan first identified the strectch of railbed between Redmond and Issaquah as a critical future link in the Regional Trails System in 1971.

Burlington Northern Santa Fe Railway ceased operations on the track in 1996. Cascade Land Conservancy acquired the corridor in April 1997 and King County purchased the property in September 1998. The following year, King County began a robust, region-wide community engagment effort to guide development of the Trail Master Plan.

Why is King County developing the East Lake Sammamish Trail?

The East Lake Sammamish Trail is currently an 11-mile “missing link” in a 44-mile-long regional trail corridor that will connect the Burke-Gilman trail, the Sammamish River Trail, the Marymoor Connector Trail, and the Issaquah-Preston Trail, linking Seattle to the Eastside and the Cascade Foothills.


A trail for the community – At the end of an eight year planning, outreach, and environmental multi-use process, a prefered alternative for the Trail Master Plan was identified and approved. King County began finalizing the plans on the type of use, location, alignment, and width of the trail to establish King County Parks regional trail standard. By 2008, design of the 11-mile link potion of paved trail had begun, and in 2011 the Redmond segment opened as the first paved stretch of the East Lake Sammamish Trail.

Design and construction of South Sammamish Segments A and B will continue to adhere to the agreements made in 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.
