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

What a beautiful section of trail I started at Rattlesnake lake road up and through the pass tunnel and back nice hard packed gravel.

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.

My wife and I finally rode this trail over the weekend and we couldn't be more thrilled at the great workout it provided us. Trail started out through a quiet section of Renton, but got louder as it followed a busy road. The trail provided a lot of chances to see the Cedar River. We stopped and turned around at the end of the paved trail and just raved at the views and the total experience. We will definitely come back and ride the whole stretch.

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.

Rode the whole trail first 12 1/2 miles paved too bad it is so close to road. The last part which is a hard packed gravel is very pretty all in woods crossing back and forth over river

Road this from Ellensburg west for 26 miles with 38mm tires. nice smooth trail going through history. met some gravel riders riding from North Bend to Cle Elum 50 miles and back for a gravel century in a day.
