Cedar River Trail

Route Description for Cedar River Trail

Cedar River Trail is a multi-use pathway that connects Renton and Landsburg. The trail closely follows the Cedar River from Lake Washington to Landsburg, offering pretty views at multiple points along the route. The trail is frequently used by walkers, runners, and bikers. You can pick it up at many points along the way and just take it as far as you prefer to go.

While you can pick your own adventure on the trail, we’ll describe it from the Renton trailhead. Bikes aren’t permitted on the first 1.0 km of the trail from Renton, but you can take Nishiwaki Lane and then hop on the trail later.

There is parking near the lake, but note that most of the spots here have a 4-hour limit. If you plan to stay longer you may need to park further away.

Walking alongside the river, you’ll notice that it’s not always very obvious which side to cross each bridge on. We recommend staying on the north side of the river for about the first mile and a half.

Crossing the road safely can be challenging near Bronson Way N. We recommend going left at Houser Way for 46 m. Use the crosswalk to cross, then head underneath I-405 on the underpass. Cross the river on the bridge and then continue east.

At 4.8 km, you’ll meet the south side of the Maple Valley Highway. There’s a bit of road noise here. Cross under the road after another 1.4 km. You’ll stick close to the highway for the next few miles. Watch for Natural Areas along the river as you go.

You’ll reach the end of the paved path at 20.4 km. There is a junction with the green to Cedar River Trail here. Keep going along packed gravel.

It’s about 7.6 km from here to Landsburg, where the trail officially ends.

Trail Highlights

Cedar River

The 72.4 km long Cedar River flows from the Cascades to Lake Washington. The Cedar River Watershed provides drinking water for Seattle and the surrounding area. Care for the river was taken on by the Friends of the Cedar River Watershed in 1996. This group organized community involvement and spearheaded plans to protect the river's salmon, restore riverside habitats, and promote environmental stewardship. The first and second-growth forest along the river is home to a variety of species and the waters themselves contain three kinds of salmon and one species of trout.
