I give 5 stars to what has been completed. It is definitely an urban trail, but I love that it stops by parks along the way. It is so much nicer to be able to have a trail to not only take walks but to travel between areas to shop. I look forward to its continued development. I hope that all the cities involved do a better job of keeping pedestrians in mind as they plan for the future.

Late October 2019 Started in Bellingham on the South Bay trail to Fairhaven which connects easily to the Interurban Trail, about 9 miles total each way... very nice ride with fantastic views of Bellingham Bay and some of the San Jaun islands. Most of the trail is flat and well packed but you do have to descend into and climb out of a couple of gorges where there were once rail bridges now long gone. Historic Fairhaven is a beautiful spot for lunch, lots of options. Will definitely do this one again!

Did the 10.1 mile trail ride starting in Carnation and stopping at the Tokul tunnel yesterday, Oct 14. The trail is in great condition and fall colors magnificent. First time on this section and found the elevation gain very easy to handle. Hope to get a few more rides on this trail before weather window closes. Highly recommend

My entire family has enjoyed using this bike path for many years. The views are beautiful, especially near sunset. The path is heavily used by walkers, joggers, cyclists and rollerbladers. Always using proper trail etiquette, passing "on your right" and this should reduce the possibility of any mishap.

I've ridden the entire length of this trail once by myself and twice with my wife, who is new to riding. We both enjoy the ever changing scenery as the trail hugs the Green River. There are some iffy spots, mostly late in the day, due to some homeless encampments under some of the bridges/overpasses. On those portions of the trail, I usually take lead with her riding close by.
Bikers we've encountered are generally friendly folks.

I ride this trail twice a week from Everett to work in Mountlake Terrace and mostly love it. The areas in which you actually ride on the trail are wonderful. That means the sections from about Lynnwood Park & Ride thru Everett. I often am alone on those sections of trail, and I love to look over at stopped traffic on I-5 and feel smugly secure that I'm getting to work faster and with better exercise than those people.

The negatives of this trail are as people described: it starts and stops and sometimes there are sketchy people. There are several streets in which the trail stops and the rider has to cross streets -- 128th Street, 164th Street, approaching the back side of Alderwood Mall, and most of Mountlake Terrace including 220th Street. Those aspects of the trail are frustrating because they break the riding flow and make bikes feel like second class transportation. I especially hate the uphill/downhill approaching the mall, as it required riding on the road up a hill. It's a shame the city of Lynnwood couldn't widen that bridge to allow for bikes. Near 128th Street, the trail ends at an apartment complex and you have to ride through an area congested with kids in the afternoons, requiring weaving through people. Then on the other side of 128th, towards Everett, there are occasionally sketchy people who you can just bike away from.

Despite these frustrations, I love my Interurban Trail and am happy to ride it frequently. It's been improved over the years, especially thru Lynnwood, and riding it is a great way to start and finish the day.

The trail was fantastic. The road noise from construction going on the street above was very scary for me and my dogs. We parked at Blyth Park, well maintained park area and easy access to the trail. It was a HOT day and it was nice to find a place where the dogs could jump in the water and kool off.

Nice trail a little bumpy in places and overgrown with grass. The Darrington end starts by the airport and is near the IGA. The trail runs behind the Bluegrass festival grounds which gives great views of Whitehorse mountain. There is a wash out in one section near the river. It’s ok for bikes to ride by, or walk past. The trail is in the woods or in people’s back yards to Fortson Mill. The old mill is off in the woods and there is a parking lot. I went another mile west until there was a bridge marked closed. I had previously tried from the Centennial end, but the landslide still was blocking the trail. Hopefully more will open soon.

1. People use this trail as their daily commute.
2. Very well maintained.
3. Not much bumps but there are quite few.
4. You can turn off your mind and just bike on this trail.
