Great trail. Looking forward to the continuation at 72nd ST E and Waller Rd E into South Hill.
I had not been on this trail for over a decade. I was in the area so decided to try it again. This time I made a nice loop route connecting the Green River Trail with the Interurban trail to add some nice mileage. I took the trail on 4/11/25 on a Friday morning from the Starfire Sports Complex. There was very low traffic on the trail and I enjoyed meandering along the river with it's curves. This is a peaceful journey through a high metropolitan area. It's a great break from the road traffic. At every crossing of a major street there are signals to use. I highly recommend trying out this trail and using connections for a decent bike route.
Good paved bicycle path that is separated from 4 lane road by a strip of grass. It goes uphill from in the north direction so you can get a good leg burn on the way up and then cruise downhill afterwards. Scenery is a mix of vegetation, homes , and businesses that are typical of this area.
I can’t wait for this trail to be completed!
It's a nice trail. I've walked it a few times. Areas to sit. Safe crosswalks. It's got a few greenbelt areas that are interesting to explore. Pretty safe. Great for a bike ride too, I have biked it. Had to review it. It's worthy of a hike.
One of the things that stands out to me is how well people take care of this trail. After a storm, I often find that the trail is cleared, branches (big and small) are removed, and other obstacles are taken care of. I often see signs of saws or chainsaws to deal with larger trees or branches that have blocked the road. Good job, volunteers and clean-up crews!
We started in Akron and rode about 18 miles north. Loved it!!!
I was on the Yelm - Tenino trail today when about a dozen riders on E-Bikes and E-scooters came down the Chehalis Western trail to where it meets the Yelm trail. Is there some exception for E-bikes? I thought they would be considered "motorized" vehicles. What were they doing on the trail? So outside of the irritation I felt about that, the trail itself was great! I'm just getting back to riding after knee replacement so a relatively level trail out in the country that I could do some easy distance on was perfect!
My trailhead is always the lot at 423 Washington Av SE, Orting; heading east to Buckley from there avoids the majority of urban and traffic.
But the Spiketon Ditch Bridge 9 miles on (1.6 mi past S. Prairie) is currently closed, as "structurally compromised." Trail is blocked. It's a turnaround.
I do truly love the 9 miles that are open, sections along the Carbon River, others lined with woods, through farmlands, in and out of the small town of South Prairie, views of Mt. Ranier, ...
Scenic and the natural restoration is very well done, especially the interpretive signs and benches. Signage along the parkway to trailheads was lacking as were trail/milage markers along the way as was drinking water. If you go solo, take the time to investigate and plan a route.
Much of the asphalt is severely buckled in the miles heading toward Bothell. So many that you cannot avoid or bike around big sections of long and high ridges and cracks. The bumps cover far more area than smooth pavement. There is also a stretch of very large rock gravel on a narrow, elevated path near where the path intersects with 405.
