Another techy double black, but definitely not the most difficult double black on the mountain.

Flow Map

Flow is yet another rocky double black diamond trail in the Mammoth Mountain Bike Park. A few booter-style jumps provide air opportunities in the midst of a chunky, brutal descent. Some sections of the trail feature cascading log drops followed up by trenched-out eroded sections.


While Flow gets a double black diamond rating on the trail map, it’s definitely not the most difficult double black on the mountain.

Very steep, difficult, narrow singletrack with widely variable and unpredictable trail conditions. Unavoidable obstacles could be 15in/38cm tall or greater, and unavoidable obstacles with serious consequences are likely to be present. Obstacles could include big rocks, difficult root sections, drops, jumps, sharp switchbacks, and more. Ideal for expert-level riders.
