Sammamish River Trail

The Sammamish River Trail succeeds by making an ordinary suburban valley feel spacious. For 10.1 official miles—about 16.3 kilometres—it stays close to the river while moving from Marymoor Park through downtown Redmond, protected farmland and Woodinville to Bothell. The riding is technically easy, yet the surroundings keep changing enough that the route feels like a small journey rather than a fitness loop.

Start at Marymoor Park, one of King County’s great all-purpose public spaces. Before turning north, you can watch activity around the velodrome, gardens, sports fields and river launch, or simply use the park’s open lawns to organise the group. Marymoor Village light rail now provides unusually convenient car-free access, which makes a point-to-point ride far more practical than it once was.

The Redmond section mixes civic life with river ecology. Dudley Carter Park is a particularly worthwhile pause: its Haida House replica and the story of centenarian woodcarver Dudley Carter bring art and cultural history into a corridor that could otherwise be read only as transport infrastructure. Nearby trestle and trail connections recall the river and railway systems that shaped Redmond’s street pattern.

North of the city, the valley opens dramatically. Sixty Acres Park and surrounding agricultural land create long views toward the Cascade foothills, and the trail’s gentle grade invites conversation rather than concentration. This is the most memorable section on a clear day: cyclists, runners and equestrians share the corridor while working fields preserve a sense of rural space within the metropolitan region.

Woodinville changes the mood again. Wilmot Gateway Park supplies lawns, river access and a practical rest, while nearby wineries, breweries and cafes make it easy to turn the ride into a social outing. Commercial stops require a small detour and current-hours check. If alcohol is part of the day, keep it modest, eat, hydrate and remember that the trail remains a busy public route.

Beyond Woodinville, vegetation closes in around quieter river bends. Restoration areas tell an important environmental story: the Sammamish was straightened as part of a federal flood-control project completed in 1966, and contemporary work now tries to recover floodplain and salmon habitat within that altered system. The ride becomes a lesson in how cities renegotiate waterways over time.

Park at Bothell Landing makes a satisfying finish. Historic buildings, the pedestrian bridge, lawns and riverside spaces reward a final walk around before transit or return arrangements. The Sammamish River Trail also connects directly with the Burke–Gilman, so stronger riders can continue toward Lake Washington and Seattle; this guide deliberately ends in Bothell to keep the ride approachable.

Practical limits matter. This is a popular shared trail, not a private cycleway, and its flatness can tempt riders to carry too much speed. Flooding can affect low sections near NE 95th Street in Redmond, wet leaves and frost can reduce grip, and seasonal maintenance may appear with little notice. King County did not list a specific active closure on the official trail page at this review, but riders should check current alerts immediately before departure.

King County publishes the official length and surface but no definitive total-ascent figure for this exact route, so no elevation number is invented. A verified GPX, Strava, Komoot or Ride with GPS route is not supplied here; use King County’s official trail map for current navigation and do not confuse the separate 2026 East Lake Sammamish Trail culvert closure south of Marymoor with the Sammamish River Trail itself.
