Passes through Lake Wilderness, "4 Corners" area of Maple Valley and takes Old Railroad Grade through the west side area adjacent to Black Diamond Open Space (BDOS) mountain bike park. Mostly good quality public gravel trail, with just a little singletrack below the Toy Tree trail, to transition to gravel roads down to Lake Sawyer. Lots of opportunities to venture onto singletrack at BDOS.

Tried to find the rest of this trail today. Went through a neighborhood then to a non existent bridge…did I miss a turn?

I couldn’t find this today. Just took me to a non existent bridge.

We made this into a loop by taking neighborhood streets around Lake Sawyer, and rejoining our outward path where it crosses 241st Ave SE, near 169 and BDOS.
