Wife and I rode this and it is paved w/good surface, well kept, clean, good sight lines, benches and trash cans. Protected by fences. Only downsides I noticed was a lot of private driveways that cross over and lots of people’s houses right at trail edge which can be a bit much. Some nice views of the lake, lots of trees. Fun to go from Issaquah to Redmond! Overall we were impressed and lots to offer.
This trail, while very long, is only on rail corridor for a small percentage of time. When riding this trail, you need to keep in mind that the only goal of this trail construction was to have a peninsula wide trail. There was never any intention of creating a good riding experience. So when you have areas that are 10%+ grades, get suddenly turned out on a road, or just question the wisdom of route decisions, remember the one and only goal and enjoy the good parts. If you want a real rail trail experience head out to the Spruce rail trail in Olympic NP. The best part of the trail is from Port Angeles a few miles east towards Sequim, which is rail trail until you hit the 10% grades.
I turned around early in fear of getting lost! I had to stop a few times to figure out where I was so eventually I just navigated back to my car. The spots I rode were great though!
Agree with Hodge Podge as to the structure of the trail. Goes off old rail line on numerous occasions, has numerous road crossings and is very narrow is some areas. A large portion of all sections travels through private property with barking dogs and junk all over the place. Too bad trail could not have followed original rail line
A fun walk through an urban Beacon Hill neighborhood safely winding through the center of a wide median. Trees provide scattered shade and plenty of benches to tie that loose shoestring. No sign of any bikers, but passed a few friendly faces including a Mom with a stroller, grandmother and grandson, and an elderly walker listening to audible music on his phone. Plenty of street parking near Ferdinand street. We found a shady quiet spot to park. You can walk 30 minutes and use the restroom at the community center if needed.
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.
Ok section, kind of dull. Agriculture & cows. Found a bit of shade by a grain elevator for lunch. Several washouts filled with tumbleweeds as you get closer to Lind.
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.
