I haven't done much maintenance on this site recently, but most of the bus hikes in here should be doable although some bus routes may have changed. Check before you go!
There is an active bus hiking Meetup group in Seattle - check them out! They do some of the hikes described here.
The increasingly popular ride service Uber can fill in where bus service is lacking. I did a long hike from Marymoor Park to Sammamish State Park on the lakeshore trail, and rather then trying to return from Issaquah using the sparse and indirect bus routes, I used Uber. Worked quite well and the ride back was quick. If Uber is operating in the North Bend area, that would open up a lot of interesting hiking possibilities.
Added a new walk along Thornton Creek in north Seattle
