The Green River Trail runs about 12 miles through Tukwila and Kent, Washington. Parts of it have yet to be completed, so in those sections you have to ride on streets.

We’d rate this a 5, especially the southern part. The river is almost always in sight, and the scenery varies from light industry to housing developments, parks, golf courses, open fields, and finally farms (an endangered species in this sub-urban area). Always, however, you are in a little strip of a park with trees, grass, flowers, and of course the river. Frequent places to rest (benches, parks.) You can make a really nice loop by crossing the river at the bridge before the intersection with the interurban trail, and riding along a quiet road (Frager), next to strawberry farms, golf course, some open land, a few houses. Some of this is a road and some was a road that is now closed to cars. There are several bridges that allow you to cross back to the Green River trail (we crossed at S200th St, but it looks like you could even go to the next bridge.
Another nice loop is to start at Fort Dent and go down the Green River trail and back the interurban trail, along bike paths the entire way.
Could not find contact info, but wanted to let you know our site has a new url, please make necessary updates. Specifically for this page http://www.kingcounty.gov/recreation/parks/trails/regionaltrailssystem/greenriver.aspx
Thank you
Thanks for the update! I think I’ve found and fixed all the links.

Problems with the Howard Hanson Dam upstream from the trail, will result in some or all of the Green River Trail being covered in giant sandbags. The sandbags are intended to raise the height of the river bank and prevent flooding in the valley. Recent news reports say the trail will remain open to foot traffic only, not bicycles or trikes!! No word on when or if the sandbags will be removed.

The southern entrance onto the Green River trail from the Interurban trail heading north near S. 259th ST in Kent is closed about 1/8 of a mile up the trail.
It looks like the Green River could be closed in places for up to 5 years.

I finally rode the last segment of this trail north out of the Starfire Sport Complex near I-405 in Tukwilla. The trail essentially follows the river with segments that run on a widened sidewalk before it eventually comes to an end just southeast of South Park. But the rider can pick up the Duwamish River Trail shortly after by following the bike signs and riding through the back roads in South Park. It eventually does return to a dedicated bike path, it is also possible to make your own street path by simply staying close to the river before you locate the path trail head again.
While not the most beautiful terrain I’ve seen — basically an industrial park and urban development along a once pristine river — I still found value in this ride… particularly with it’s ending. The true gain comes from circumnavigating the city skyline and intersecting with the Alki trail for some great waterfront riding. In fact, I just kept going and continued another 3 miles or so around Alki Point to the Fauntleroy ferry terminal. These local streets along the beach take the rider through Lincoln Park before hitting the terminal.
Avoid the mayhem of a business day and do this on a weekend and you’ll find the roads to have low volume.
