FATMAP difficulty grade
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.
