BDOS (Black Diamond Open Space) is east of Hwy 169, south of Henry's Ridge (separated by the railroad tracks) and north of Summit Ridge. Evergreen Mountain Bike Alliance, the Black Diamond Trails Club and King County Parks are currently designing and building a 5-10 mile trail network. Construction started in Jan 2015.

There are several older trails that are still rideable: Rte66, Masterlink, Kathleen, Spooky, Super Charger, etc.
