The West Fork flows for in an easterly direction from its origins at Red Box Gap, in the San Gabriel Mountains, eventually reaching San Gabriel Reservoir where it is bridged by SR 39 just above its mouth. The major tributaries of the West Fork, from upstream to downstream, are Devil Creek, Bear Creek and the North Fork San Gabriel River. A large portion of the watershed is situated in the San Gabriel Wilderness, whose southern boundary is formed by the West Fork.
