They do many of the bus hikes described in this guide.
Here's an active Seattle transit hiking Meetup group:

The new Snoqualmie Valley Transit service, run by the Snoqualmie tribe in conjunction with Metro, offers a dial-a-ride bus that can take you to a number of trailheads near North Bend, including Mt. Si, Twin Falls, Rattlesnake Lake, and Snoqualmie Point Park. They also have a scheduled bus that runs up and down the Snoqualmie River valley to Duvall. Check out their website or call them at 425-888-7001.
I've added a new hike located in Snoqualmie Ridge in east King County.
9/21/2013: Major changes are coming to bus service in the Snoqualmie Valley on September 28, affecting access to a number of hikes in the area. The Metro 209 bus is becoming a peak-only bus, with all-day service to North Bend being provided by a new route, the 208. This bus will take a new route between Preston and the town of Snoqualmie through the Snoqualmie Ridge development. Service along the river valley between Duvall and North Bend will be provided by a private bus line, Snoqualmie Valley Transit. The Metro 224 route starting from Redmond will be truncated in Duvall.
All this means that access to hikes near Carnation, Fall City, and other points in the valley may be slower and more complicated, depending on the level of service provided by the new Snoqualmie Valley Transit. Reaching the famous Snoqualmie Falls will now require a mile or more of walking from the new 208 route.
On the plus side, the trails on Snoqualmie Ridge will be easier to reach, and it may be possible to walk to the vast DNR logging road network on the west slope of Rattlesnake Mountain. The travel time from Issaquah to North Bend on the new 208 route will be significantly faster, too.
