"BDOS offers lots of singletrack and variety, but is mostly based around XC,” according to EvergreenMTB.org. "There’s sic a few freeride and downhill trails here and in the nearby Summit Ridge & Henry's Ridge, but by NW Washington standards, BDOS is pretty flat."
This massive, complex trail system includes mile upon mile of interconnected non-motorized singletrack. In total, there are at least 64 different named trails in this trail system, plus numerous connections to other nearby trail systems.
You can easily construct a ride of any length and any difficulty in the Black Diamond Open Space—from a quick couple-mile jaunt in the woods, to this meandering 22-mile loop, or an even longer ride if you start connecting every single possible trail option that you pass. If you’re looking for a respectable pedal, try out this recommend trail combination, and then continue adding or subtracting trails from here!
Mostly stable trail tread with some variability featuring larger and more unavoidable obstacles that may include, but not be limited to: bigger stones, roots, steps, and narrow curves. Compared to lower intermediate, technical difficulty is more advanced and grades of slopes are steeper. Ideal for upper intermediate riders.
