I have walked the centennial trail in several places, mostly in the Lake Stevens section, but also some Snohomish and Arlington as well. The trail is mostly flat, although you do encounter the occasional small hill. Parts go past Little Pilchuck Creek with some little trails that allow access and it goes along the Pilchuck river in areas as well. Further north it passes Lake Cassidy with a dock that you can walk out on to see the lake...idk if swimming is allowed here, but I wouldn't recommend it anyway, the lake is gross. The whole trail is paved and wide, which is nice as it can get fairly busy. I recommend the Machias trail head park if you are walking with kids because the park there is fun, especially for around toddler age. There are picnic tables and grassy areas along the trail if you want to have lunch. I don't know why this website says you can camp, I have never seen camping along the trail, but I suppose it could be in an area I haven't walked yet. Everywhere I have walked has also been very clean and well taken care of...the only section I dont particularly like is the spot that runs along Old Hartford Road in Lake Stevens because it goes next to a sanitation business and it stinks to high heaven...other than that, it's great for a daily walk so long as you be sure to keep yourself safe in the areas that are really secluded!
I have only walked the centennial trail from downtown Arlington North and back but this section is very well maintained and it is paved with the exception of the horseback trail. Heading north out of Arlington you pass Haller Park (which has public restrooms and river access) and cross the Stillaguamish River. After a fairly short distance the horseback trail branches off and the main trail starts to mildly incline. there is a couple of picnic tables after 1.5 miles or so. At just over 3 miles you reach the Bryant Store (which has a beer garden but allows all ages to sit together if you are a family in need of a cool down). The trail is used by everyone from day time walkers to experienced cyclists and can be fairly busy. Everyone is friendly and welcome from horseback riders, cyclists, dogs on leashes, moms with strollers, runners and everyone in between. Part of the trail is somewhat secluded so those who are walking or running alone please use due caution, be aware of your surrounding and don't turn music devices up loud enough that you are unable to hear anything else. Happily for cyclists there is now a bike shop on Olympic Ave in downtown Arlington if you run into any mechanical issues.
I find this to be a very peaceful and relaxing section of trail and would invite all to come experience the area. this is a nice section of trail no matter what the weather.
