Cedar River Pipeline trail/road

The Cedar River Pipeline road, or trail, leads from the Landsberg Trailhead of the Cedar River Trail northwest along the south bank of the Cedar River (the county's Cedar River Trail is on the north bank). The Pipeline Road from Landsberg Rd eastward is one of the main access points for the Danville-Georgetown Trails that lead off from either side of the road at various points along the first few miles of it, but the road itself continues and can be ridden for 3.5 miles before being blocked off by roads and subdivisions in Maple Valley. The road west of Landsberg Road is closed to the public.

Landsberg parking areas (blue marker) are located on either side of the Cedar River off of Landsberg Road.

From the west/south: Four Corners (between Maple Valley and Black Diamond, the intersection of Maple Valley Highway 169 and Kent Kangley Road/Highway 516), go east on Kent-Kangley Road and take the first left onto SE Summit Landsberg Road. Where it ends and joins Landsberg Road, turn left and proceed down the hill toward the river. The parking area south of the river is on the left at the entrance to the Cedar River Pipeline Road and holds only a few trailers; however, the parking area on the north side of the river, again on the left, has room for many more and is the entrance to the Cedar River Trail.

From the north: Landsberg Road is also known as Issaquah-Hobart Road/SE 276th. From route 18, go south on this until the road turns and the name changes. The parking areas (see above) will be on the right side of the road.

Alternate parking (yellow marker) for a trailer or two can be had where the Cedar River Pipeline crosses SE 248th St.
