This trail is excellent from Snohomish up to Armar. Once it enters Arlington, it is mostly a glorified sidewalk and definitely not fun to get through. But once you do get through Arlington, the last bit north to trail end at the Nakashima barn is excellent as well. Too bad there is that ugly stretch in the middle.
