"The Cedar River Trail makes a beeline on its way out of Renton across the valley toward the foothills of the Cascades. It’s no wonder. This popular rail-totrail path follows the route of the Chicago, Milwaukee, St. Paul, and Pacific Railroad, whose highballing silk trains historically rushed that precious commodity on the final leg of its transport from Asia to East Coast markets."

"Do you ever, on a flat and open stretch of trail, just tune out your surroundings and listen to your body working with your bike? Legs operate like pistons, heart churns like an engine. Try this on the Cedar River Trail’s flat, open route, and you might get a feel for the trail’s first use: as a railroad. The trail, paved from Renton to Maple Valley then continuing to Landsburg as gravel, began life as a part of the Milwaukee Railroad. Reappropriated by the government through the “railbanking” mechanism, it’s a great jumping-off point for exploring the cusp of rural lands in south King County. The three-hour ride is at times loud and busy, but the exploration of the charms still existing in May Valley make it a worthy ramble through the civilization happening southeast of Seattle. And once you see the maze of suburban roads emanating from the trail, you’ll ?nd other rambles to explore."

Great road biking trail. It's busy on the weekends, so be prepared for rollerbladers, people who like to talk and walk in the middle of the path, and other bikers.

While the initial ride was comfortable and nice we found once we reached Maple Valley the trail was closed for construction, so took a small detour around it and found a nice little eatery with an excellent lunch. The trail was also under construction further down the road so we veered off onto the Lake Wilderness trail. Would like to do again when the construction is completed.

This is fine for what it is. I only jogged about an hour on it, so I haven't yet covered the whole thing. Parking near 405, and jogging from there west toward the water, it abruptly ended after about a half mile (though it had appeared on the map to go all the way to the water). So I turned back around and headed the other way. Going away from 405 (heading east) it is a nice, paved, shaded path for a couple of miles and then it cuts close to the highway, so it's kind of loud and not very peaceful. Flat. If you need a path to jog in the city, this works well esp. if you're meeting a running partner since it's so close to 405. I would never choose this as a place to take a great outdoor walk though as it's near the highway and noisy (at least the 3-mile stretch nearest 405).
