As of Sept 4, 2017 the landslide blocking the trail west of Concrete had still not been cleared. Try as we might we were unable to find a trailhead with a portapotty in the vicinity of Challenger Crossing. There's supposed to be one there.

The trail is quite flat and the scenery is lovely, so for those two key elements it is an excellent trail. But the surface condition is so bad that it detracts from the enjoyment. It would take very little effort to correct most of these problems. Maintenance on this county trail seems to entail throwing down piles of loose gravel. Even the widest tires will sink into loose pea gravel with no stone dust, so you have to be constantly alert to these wide areas. It doesn't help that these areas occur more frequently at road crossings. Also, the barricades at road crossings are unneccessarily enormous and positioned in a way that you cannot easily get around them. riding around the outside can be done at alot of them, but it's not consistent. The barricades could be unlocked and opened just a little more so a cyclist could ride through, while still blocking road traffic. As it is, there are too many crossings to have to stop and walk through 2 of these at every side street. The area at mile 4.8, near Minker Creek, is abominable. The ladt straw for us was how rough the trail got as we approached Hamilton. We finally gave up and turned around before we got to town. We typically ride 12 to 14 mph on good stone trails, but we were reduced to 8 mph for this trail.

talked with a Skagit Parks employee last week, and he said that the landslide blocking the trail west of Concrete is due to be removed in the next week or two

I really enjoyed this bike trail; It has a breathtaking view and my bike ride was refreshing! The trail was short but I biked it twice. I can't wait to go again!

I think without this map it would have been hard to follow this trail when it is on the surface streets. While the trail is in the green belt it is a nice afternoon walk.

Rode this trail over Memorial Day weekend. The weather was lovely, but sadly the trail was blocked about 1/2 mile east of Challenger Rd. There was a landslide and a large tree is blocking the trail. You can't go over ,under or around the tree. Apparently, you can ride up Challenger Rd and get back on the trail. Check a map, before you. do this. Trail needs a bit of cleanup. lots of horse pucks in the middle of the trail.

Did the entire trail in both directions plus the extra six miles to match my age of 67. It was a wonderful experience, relatively quiet even when the trail ran adjacent to roads. Loved the scenery, met some very nice people, and the discovery of Nutty's Junk Yard and Grill was worth the 20 mile ride to get there. The deep fried mushrooms and burger did a great job of replacing the calories I burned on the ride. The northbound leg was a bit slower than coming back south so I would recommend starting in Snohomish. Would definitely ride this trail again.

My wife and I recently rode this trail and found a little too rough for cyclo cross bikes the scenery was indeed spectacular but switched over to SR20 on the way back which was much better. The road has a nice wide shoulder and we felt safe.i would imagine that horseback riding or cross country skiing would be much better. When in Sedro Woolley you should pop in to the market store on Metcalfe street. They have a little bit of everything

As a round-trip, this makes a beautiful metric century ride. There is parking at both ends as well as many spots along the way. The trail is wide and in great condition. While the area around Arlington runs along a busy street and through light industrial sections, most of the trail is Royal and quite scenic.
